#lithium ion Battery

[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.”

A few more photos to explain how badly designed a cheap vape pen is.

First off the pressure sensor that activates the heat for the vapour is very sensitive, it's at the opposite end to your mouth, once dropped and broken open - as this one was - just gentle pressure on the white button activates the heating element (and some LEDs).

Then you've got this hell battery.

A well-designed lithium-ion battery looks a lot like the Energizer one: a solid metal casing, caps at either end to stop electrical overload underneath the casing, if you sawed open the casing (basic wire cutters or a hand saw would take you at least 10-20 minutes to get into it) there'd be the densely wrapped "jelly roll" of graphite on thin plastic layers drenched in solvents like you can see in the next to last photo (I pried open the foil - don't do this).

This battery is not only barely covered with some tape and foil, it has metal bits going right into it, where the solvents can wick out or water can wick in. The solvents smell like nail polish remover (not quite like pure acetone, sweeter). They're toxic in high doses, in water or in an enclosed space but they're not the primary danger.

The stuff in the densely packed layers likes to ignite, violently, when in contact with the water in air. If you toss water on it or it gets waterlogged: the fire gets worse. Now imagine it gets crushed in the rubbish compactor and the firefighters get out the hose.

This uncased battery design will probably not stay legal for long but until legislation kicks in: if you see dropped or binned vape pens, bag them or put them in a pocket without other items (don't open them up like this idiot) and take them to any battery deposit place: your local supermarket should have special drop off bins.

Can Lithium Ion Batteries Leak?

Lithium ion batteries are highly efficient energy storage devices, and they have revolutionized industry in many ways. It is important to understand the potential risks associated with these batteries, including their propensity for leaking.

Leaking of a battery can be caused by several factors, such as overcharging or prolonged use at high temperatures.

When lithium ions escape from the cells, they may cause damage to surrounding objects or people.

The good news is that modern lithium-ion batteries are designed with safety features that help reduce the chance of leakage occurring.

These include temperature sensors that cut off charging if it reaches an unsafe level and pressure valves that act as a release mechanism should too much gas build up inside the cell.

Additionally, manufacturers typically provide warning labels on products containing lithium-ion batteries informing users about proper usage and cautioning against overcharging or exposing them to excessive heat.

By following these guidelines, the risk of leaking can be greatly reduced.

"It seems like a new Silicon Valley startup could change the face of the battery industry forever by utilizing 3D printers to print solid-state batteries.

Solid-state batteries have advantages over lithium-ion because they aren’t flammable, they’re more easily recycled, work in extreme cold, and have greater energy density.

Solid-state batteries have traditionally been difficult to machine manufacture. But by using 3D printing arrays filled with powder, Sakuu systems can make these batteries not only using 40% less material, but in almost any shape the customer might want.

An electric bike could be powered by a battery that hugs a section of the central chassis, or a smartphone’s battery could run all the way around the frame of a circuit board. These unorthodox shapes are just one of the many advantages that Sakuu believe they can offer.

“Many people have built cells in the lab, but they have not been able to scale,” Sakuu CEO and founder Robert Bagheri told Fast Company. “Our vision started with that scalability in mind.”

The array, known as a Kavian, is much smaller than the traditional, “roll to roll” battery manufacturing methods, and because the powder loaded into the 3D printers can be extremely precise, there’s a 40% reduction in materials usage—a huge cost savings over competitors.

The batteries they print can be charged to 80% in just 15 minutes.

Because they can be printed in any shape, all kinds of clever innovations are possible, in all kinds of industries from e-mobility products to wearables and small devices. The company is even working with an aviation company that wants solid-state batteries for their aircraft with holes through the middle of it to help with heat management."
