A well written explanation involving Lithium Ion Batteries. 👇

Understanding Thermal Runaway in Lithium Ion Battery Fires. Thermal Runaway Explained:

Thermal runaway is a chain reaction within a lithium-ion battery that can lead to catastrophic failure, resulting in fires or explosions. Here’s a step-by-step breakdown of what happens during thermal runaway:

1. Initial Trigger: Thermal runaway can be initiated by several factors, such as physical damage (e.g., puncturing or crushing), overcharging, manufacturing defects, or exposure to extreme heat.

2. Internal Heating: Once triggered, a part of the battery starts to overheat. This can be due to an internal short circuit or a chemical reaction within the battery.

3. Chain Reaction: The heat generated from the initial trigger increases the temperature inside the battery. This heat can cause other parts of the battery to react, generating even more heat.

4. Rapid Temperature Rise: As the temperature rises, the electrolyte inside the battery—a flammable liquid—starts to vaporize and decompose, producing gases. This further increases the internal pressure and temperature.

5. Gas Release and Ignition: The increasing pressure can cause the battery casing to rupture, releasing flammable gases. These gases can then ignite, leading to a fire or explosion.

6. Propagation: If the battery is part of a larger battery pack, the heat and flames can spread to adjacent cells, causing them to undergo thermal runaway as well. This can result in a large, intense fire that is difficult to control.

Key Points: - Difficult to Extinguish: Thermal runaway fires require massive amounts of water to cool the batteries and stop the chain reaction. Traditional fire extinguishers are often ineffective.

- Toxic Gases: Burning lithium-ion batteries release toxic gases such as hydrogen fluoride, which can be harmful if inhaled.

- Reignition Risk: Even after the fire appears to be extinguished, there is a risk of reignition. The battery cells can remain hot and unstable for hours or even days.

Safety Measures:

- Distance: Establishing safety distances to keep people away from the danger zone.

- Continuous Monitoring: Using thermal imaging to monitor for any signs of reignition.

- Specialized Response: Firefighters need to use specialized techniques and equipment to handle lithium-ion battery fires safely.

Understanding thermal runaway helps in appreciating the complexity and danger of lithium-ion battery fires, highlighting the importance of safety precautions and effective response strategies. 🤔

[In February, 2023], a small warehouse in the English city of Nottingham received the crucial final components for a project that leverages the power of used EV batteries to create a new kind of circular economy.

Inside, city authorities have installed 40 two-way electric vehicle chargers that are connected to solar panels and a pioneering battery energy storage system, which will together power a number of on-site facilities and a fleet of 200 municipal vehicles while simultaneously helping to decarbonize the UK’s electrical grid.

Each day Nottingham will send a combination of solar-generated energy — and whatever is left in the vehicles after the day’s use — from its storage devices into the national grid.  The so-called “vehicle to grid” chargers deliver this energy just when it’s needed most, during peak evening demand, when people are home cooking, using hot water or watching TV. Later, the same chargers pull energy from the grid to recharge the vehicles in the wee hours of the night, when folks are sleeping and electricity is cheaper and plentiful.

“We are trying to create a virtual power station,” says Steve Cornes, Nottingham City Council’s Technical Lead. “The solar power and battery storage will help us operate independently and outside of peak times, making our system more resilient and reducing stress on the national grid. We could even make a profit.” ...

After around a decade, an EV battery no longer provides sufficient performance for car journeys. However, they still can retain up to 80 percent of their original capacity, and with this great remaining power comes great reusability.

“As the batteries degrade, they lose their usefulness for vehicles,” says Matthew Lumsden, chairman of Connected Energy. “But batteries can be used for so many other things, and to not do so results in waste and more mining of natural resources.”

The E-STOR hubs come in the form of 20-foot modular containers, each one packed with 24 repurposed EV batteries from Renault cars. Each hub can provide up to 300kW of power, enough to provide energy to dozens of homes. One study by Lancaster University, commissioned by Connected Energy, calculated that a second life battery system saved 450 tons of CO2 per MWh over its lifetime...

Battery repurposing and recycling is set to play a massive role over the coming years as the automobile industry attempts to decarbonize and the world more broadly attempts to fight waste. The production of EVs, which use lithium-ion batteries, is accelerating. Tesla, for example, is aiming to sell 20 million EVs per year by 2030 — more than 13 times the current level. In turn, 12 million tons of EV batteries could become available for reuse by 2030, according to one estimate.

“Over the next decade we are going to see this gigantic wave,” says Jessica Dunn, a senior analyst at the Union of Concerned Scientists. “Companies are recognizing this is a necessary industry. They need to ramp up infrastructure for recycling and reuse.”

PSA ABOUT ELECTRIC VEHICLES

IF YOU OWN AN ELECTRIC VEHICLE AND ARE IN THE PATH OF AN ONCOMING HURRICANE AND CANNOT EVACUATE

DO NOT PARK YOUR CAR IN YOUR HOUSE

heavy hurricanes like helene and milton will bring floods of saltwater with them. saltwater is corrosive towards the lithium ion batteries found in ALL ELECTRIC VEHICLES and can cause the batteries to short-circuit, fail, or even explode. lithium ion fires take THOUSANDS more gallons of water to put out than normal electrical fires. they can and will burn houses down even during hurricanes.

PARK YOUR ELECTRIC VEHICLES ON THE STREET.

Serbian activists arrested after mass protest against lithium mining

A mass protest against lithium mining ended with the arrests and sentences of three environmental activists, Ivan Bjelić, Nikola Ristić, and Jevđenije Julijan Dimitrijević.

Bjelić was sentenced to a 40-day detention, while Ristić and Dimitrijević received a 30-day arrest for “disturbing public order and peace,” according to the first instance judgement, which legal experts called “draconian.”

The activists were arrested in the early hours of 11 August at one of the two Belgrade railway stations blocked by protesters. Thy were convicted, however, not for blocking the railway, but for disrupting public order by verbally abusing a journalist from pro-government Informer television who was reporting on the scene, according to local media.

The Higher Public Prosecutors Office in Belgrade announced on 11 August that all those who blocked the railway would be prosecuted. Lawyer Rodoljub Šabić, former Public Information Commissioner of Serbia, called the sanctions “draconian” and an intimidation attempt. The lawyer of the arrested activists Marko Pantić stated:

It is alleged that they obstructed the journalist’s work, surrounded her and shouted. In our opinion, this action must be concretised. What did they shout, where did they surround her, how did they disturb her? If they shouted ‘child poisoning’, it was not directed at that journalist personally. I believe that no one thinks that the journalist poisons children, but that it refers to the Jadar project and the whole story for which the protests were organised.

Railway blockade

The blockade of railway stations lasted several hours and ended after police intervened. Interior Minister Ivica Dačić said on Sunday that the police acted without using coercive measures and that no one was hurt. President Aleksandar Vučić declared:

The blockades and protests are not the solution. I will talk to the people about the fear of lithium mining and with those who think differently.

Zlatko Kokanović, an environmental activist and one of the organisers of protests against lithium mining, said that environmental organisations would not give up their demands for a ban on lithium mining in Serbia.

We want to send a message, you can arrest us, but we continue, we are not afraid, we are heading towards victory, to the end.

Prior to the railway blockade, some 30,000 people took to the streets of Belgrade on Saturday night to protest against the re-announcement of the opening of the lithium mine of the international company Rio Tinto in the Jadar River valley in the west of the country.

The protest was organised by the Association of Environmental Organisations of Serbia. Speakers claimed that they would not allow the mine to open due to concerns that the lithium mine would pollute water sources and seriously jeopardise public health.

Lithium for EU electric vehicles

A series of protests began following the Serbian government’s decision in mid-July to continue a project to open a lithium mine in the Jadar Valley, which was halted by state authorities in 2022 also due to large-scale protests.

On 19 July, the Critical Raw Material Summit was held in Belgrade. The meeting was attended by German Chancellor Olaf Scholz, European Commission Vice-President Maroš Šefčovič, and President Vučić. It concluded with the signing of a Memorandum of Understanding between the EU and Serbia on sustainable raw materials, battery value chains, and electric vehicles (EVs).

The EU has been expressing interest in Serbian lithium reserves in the context of reducing dependence on the critical raw material and transitioning to a green economy. Germany also showed appetite in recent years, with lithium batteries being a key element in the production of EVs.

According to the Rio Tinto plan, the Jadar project will produce around 58,000 tonnes of lithium per year, enough for 17% of Europe’s EV production. According to recent statements by the Serbian authorities, led by the Serbian Progressive Party, the mine will open in 2028 if the company complies with environmental regulations and obtains the necessary permits.

In recent years, many experts and environmental associations in Serbia have argued that lithium mining could have serious negative consequences for the environment. Widespread mistrust in Serbia’s state institutions, which would be responsible for enforcing environmental standards, has also been emphasised.

"Cobalt Red": Smartphones & Electric Cars Rely on Toxic Mineral Mined in Congo

The Democratic Republic of the Congo produces nearly three-quarters of the world's cobalt, an essential component in rechargeable batteries powering laptops, smartphones and electric vehicles. 

But those who dig up the valuable mineral often work in horrific and dangerous conditions, says Siddharth Kara, an international expert on modern-day slavery and author of _Cobalt Red: How the Blood of the Congo Powers Our Lives_. 

In an in-depth interview, he says the major technology companies that rely on this cobalt from DRC to make their products are turning a blind eye to the human toll and falsely claiming their supply chains are free from abuse, including widespread child labor.

 "The public health catastrophe on top of the human rights violence on top of the environmental destruction is unlike anything we've ever seen in the modern context," says Kara. "The fact that it is linked to companies worth trillions and that our lives depend on this enormous violence has to be dealt with."

hi this is your local car enthusiast reminding you that if you want to drive in a sustainable way, the best thing you can do is maintain your current vehicle for as long as physically possible, and if it dies on you, buy a used car with decent-to-good gas mileage. if possible, learn manual.

EVs are usually powered with lithium ion batteries, which is of debatable environmental friendliness and rife with human rights abuses. needless to mention that the US already produces an insane amount of waste and people buying new, expensive EVs en masse will make this issue even worse. simply put, in the vast majority of cases, you, as an individual, will produce less waste and pollution by keeping your current vehicle as opposed to buying a new EV.  EV sales are dependent on well-intentioned people who care about the environment not researching what they’re buying. governments & companies are advertising them and making laws in favor of them because they’re making money, not because they’re good. do not fall victim to consumerism. they are banking on you not knowing any better.

Revealed: how US transition to electric cars threatens environmental havoc

"The US’s transition to electric vehicles could require three times as much lithium as is currently produced for the entire global market, causing needless water shortages, Indigenous land grabs, and ecosystem destruction inside and outside its borders, new research finds.

"It warns that unless the US’s dependence on cars in towns and cities falls drastically, the transition to lithium battery-powered electric vehicles by 2050 will deepen global environmental and social inequalities linked to mining – and may even jeopardize the 1.5C global heating target.

"But ambitious policies investing in mass transit, walkable towns and cities, and robust battery recycling in the US would slash the amount of extra lithium required in 2050 by more than 90%."

EVs aren’t about saving the planet – their purpose is to save the car industry!

Battery Thermal Management: The Crucial Role of Temperature Control

In modern electric vehicles (EVs), the lithium-ion battery module pack takes center stage, influencing an EV's performance, range, and safety. However, these crucial power sources are sensitive to temperature extremes. Like people, batteries have their comfort zone, typically operating optimally between 15°C and 40°C. Yet, the reality of automotive environments exposes batteries to temperatures ranging from a frigid -20°C to a sweltering 55°C. What's the solution? Give the battery an air conditioner, and you get battery thermal management, which accomplishes three essential functions: heat dissipation, heating, and temperature consistency.

Heat Dissipation

When temperatures soar, batteries can experience a dramatic loss of life (resulting in capacity degradation) and an elevated risk of thermal runaway. Thus, effective heat dissipation is vital when the battery becomes excessively hot.

Heating

Conversely, when temperatures plummet, the battery's capacity may be reduced and performance weakened. Charging the battery in this frigid state can even pose a risk of thermal runaway due to potential internal short circuits. So, it's crucial to warm up or insulate the battery when it gets too cold.

Temperature Consistency

Think back to the old air conditioner in your childhood home. It would blast cold air upon startup and then take a break. Most modern air conditioners now use frequency conversion and even airflow distribution to maintain temperature consistency. Similarly, power batteries strive to minimize spatial temperature differences, ensuring minimal variance in cell temperature. Temperature consistency is paramount to battery performance and safety.

Effects of Low Temperatures on EVs and Batteries

As the heart of an EV, the power battery has a profound impact on its performance, affecting aspects such as range, acceleration, and service life. Safety is also a top priority. Battery performance is deeply intertwined with temperature, and cold climates can significantly hinder an EV's operation.

For instance, electric vehicle owners in colder regions often notice a significant drop in mileage during winter. In some cases, the range can plummet to as low as 70% of its usual capacity. Many drivers resist using cabin heaters to conserve mileage.

Low temperatures not only reduce an EV's battery capacity but also inhibit its discharge capabilities. At extremely low temperatures, the electrolyte inside the battery may freeze, leading to a severe reduction in power output.

Lithium-ion batteries are particularly susceptible to temperature extremes. At lower temperatures, the chemical reactions within the battery slow down, resulting in decreased performance and range. Charging in freezing conditions can also lead to the formation of lithium deposits on the battery's negative electrode, potentially puncturing the battery diaphragm and causing a short circuit. The safety implications of charging batteries at low temperatures are significant.

Battery Thermal Management: A Technological Solution

Battery thermal management is the solution to many of these challenges. This technology aims to maintain battery temperature within the ideal range. The approach includes both heating and cooling, to optimize battery performance.

There are several methods used in battery heating:

Battery Natural Heating: The heat generated during battery operation, discharging, or charging can increase the battery's temperature. However, this method can be slow and is rarely used in modern electric vehicles.

Blower Heating: Blowing hot or cold air into the battery pack through an external air conditioner is another method. This approach demands a carefully designed air duct and can result in uneven temperature distribution within the battery pack.

Heating Elements in the Battery Pack: These are composed of heating elements and circuits. Two common heating elements are the Positive Temperature Coefficient (PTC) and Heating Film. PTC offers advantages like safety, high thermal conversion efficiency, and rapid heating.

Circulating Liquid Heating: Liquid-cooled battery packs have become the mainstream option. This method offers uniform heat distribution, safety, and reliability. It usually features a system to facilitate heat dissipation, ensuring even temperature rises throughout the battery pack.

Conclusion

Battery thermal management is not just a luxury; it's a necessity for modern electric vehicles. In a world of varying climates, maintaining optimal battery temperature is a key factor in enhancing performance, ensuring safety, and prolonging battery life. As technology continues to evolve, battery thermal management will continue to play a crucial role in advancing the electric vehicle industry, offering the promise of efficient and reliable clean energy transportation for the future.
