#Lithium batteries

[reality-detective]

Officials are sounding the alarm about the grave dangers posed by the lithium-ion batteries found in electric vehicles.

Is it any surprise that ferry companies and underground car parks are banning EVs, insurance companies are refusing to insure them, and EV owners are struggling to sell them on the second-hand market?

How long until they are banned outright? 🤔

[clatterbane]

That was some more excitement we did not need.

Dumbass here just managed to short out a 21700 battery, of all fucking things, a little while ago. They are relatively big, they hold a lot of energy by Li-ion cell standards, and they are potentially VERY full of fire and explosion.

So yeah, working with loose Li-ion cells all the time and knowing my battery safety? (Seriously, if you want to learn a lot about that, check out that guy's YouTube channel. If you ever mess with loose lithium cells for any reason, this electrical engineer is your new best friend.)

I did notice a tear in the insulator wrap on one, but did I replace it immediately? 😩 "It'll be fine for the moment."

It was not, in fact, fine.

I then compounded this error by proceeding to charge the thing. On the way out of the charger, freshly refilled with spiciness, was when I managed to short it. Because of course I did.

No actual harm done, though, and no dramatic video like with that power bank incident years back. I was right there holding the charger when it started venting and starting to smoke. I unplugged the charger as soon as I heard worrying noises, and carefully carrying the whole thing at arm's length toward the bathroom and its big solid containment vessel just in case. In the absence of any convenient bucket of sand.

This is a slightly more complicated task when you're using a manual wheelchair, do not have a Hindu iconography number of arms, and also need to pop small wheelies over thresholds in your house. So, I called for Mr. C as calmly as my excitable ass could manage, informing him that we had a battery situation andto PLEASE bring first himself and second an extinguisher. (Which I know he has somewhere in his little lair. I couldn't safely get to the kitchen one right then.)

So yeah, then we played pass the threatening charger, and he promptly ferried it and dislodged the battery into the tub. After it had calmed down enough after a couple minutes, he actually settled on taping it to the end of a wooden stick to carry it down and temporarily stash it in one of the grills outside until he was sure it was safe to dispose of more properly.

I did appreciate the prompt cool response and assistance from someone who knew what they were doing. And the lack of bitching after things had calmed down enough for me to say what had happened. (Which I probably would have just kept to myself, if I was not expecting that kind of reception.)

As it was? There was no need for the extinguisher, or eventual cleanup from that. I don't think there were actual flames at any point. Nobody got hurt. .

That charger is toast, we needed to open some windows for a while in chilly weather, and everybody here got jolts of adrenaline they weren't looking for. That was thankfully the worst that happened.

I guess any moral of this little story would have to be that, if you're going to be handling high-powered especially loose Li-ion cells? Please be careful and educate yourself about how to do it as safely as you can. Please DO NOT do like me and turn overconfident.

Also, please make sure you have some plan in case things should suddenly go south. If you manage to catch a problem promptly, it might hopefully just turn into an unwanted adrenaline and toxic fumes situation like this one, rather than something much worse in potentially painful incendiary ways.

Children still mining cobalt for gadget batteries in Congo

A CBS News investigation of child labor in cobalt mines in the Democratic Republic of Congo has revealed that tens of thousands of children are growing up without a childhood today – two years after a damning Amnesty report about human rights abuses in the cobalt trade was published. The Amnesty report first revealed that cobalt mined by children was ending up in products from prominent tech companies including Apple, Microsoft, Tesla and Samsung. 

There's such sensitivity around cobalt mining in the DRC that a CBS News team traveling there recently was stopped every few hundred feet while moving along dirt roads and seeing children digging for cobalt. From as young as 4 years old, children can pick cobalt out of a pile, and even those too young to work spend much of the day breathing in toxic fumes.

What's life like for kids mining cobalt for our gadgets?

So, what exactly is cobalt, and what are the health risks for those who work in the DRC's cobalt mining industry?

What is cobalt?

Cobalt – a naturally occurring element –  is a critical component in lithium-ion, rechargeable batteries. In recent years, the growing global market for portable electronic devices and rechargeable batteries has fueled demand for its extraction, Amnesty said in its 2016 report. In fact, many top electronic and electric vehicle companies need cobalt to help power their products.

The element is found in other products as well.

"Cobalt-containing products include corrosion and heat-resistant alloys, hard metal (cobalt-tungsten-carbide alloy), magnets, grinding and cutting tools, pigments, paints, colored glass, surgical implants, catalysts, batteries, and cobalt-coated metal (from electroplating)," says the U.S. Centers for Disease Control and Prevention.

More than half of the world's supply of cobalt comes from the DRC, and 20 percent of that is mined by hand, according to Darton Commodities Ltd., a London-based research company that specializes in cobalt.  

Health risks of chronic exposure 

According to the CDC, "chronic exposure to cobalt-containing hard metal (dust or fume) can result in a serious lung disease called 'hard metal lung disease'" – a kind of pneumoconiosis, meaning a lung disease caused by inhaling dust particles. Inhalation of cobalt particles can cause respiratory sensitization, asthma, decreased pulmonary function and shortness of breath, the CDC says.

The health agency says skin contact is also a significant health concern "because dermal exposures to hard metal and cobalt salts can result in significant systemic uptake." 

"Sustained exposures can cause skin sensitization, which may result in eruptions of contact dermatitis," a red, itchy skin rash, the CDC says.

Despite the health risks, researchers with Amnesty International found that most cobalt miners in Congo lack basic protective equipment like face masks, work clothing and gloves. Many of the miners the organization spoke with for its 2016 report – 90 people in total who work, or worked, in the mines – complained of frequent coughing or lung problems. Cobalt mining's dangerous impact on workers and the environment

Some women complained about the physical nature of the work, with one describing hauling 110-pound sacks of cobalt ore. "We all have problems with our lungs, and pain all over our bodies," the woman said, according to Amnesty.

Moreover, miners said unsupported mining tunnels frequently give way, and that accidents are common.  

Miners know their work is dangerous, Todd C. Frankel wrote late last month in The Washington Post. 

"But what's less understood are the environmental health risks posed by the extensive mining," he reported. "Southern Congo holds not only vast deposits of cobalt and copper but also uranium. Scientists have recorded alarming radioactivity levels in some mining regions. Mining waste often pollutes rivers and drinking water. The dust from the pulverized rock is known to cause breathing problems. The mining industry's toxic fallout is only now being studied by researchers, mostly in Lubumbashi, the country's mining capital."

"These job are really desired"

Despite the dangers and risks of working as miners in the cobalt industry, at least of the some miners in the Congo "love their jobs," according to Frankel.

"When I talked to the miners there, none of them want to lose their jobs or give up their jobs. They love their jobs," Frankel said Tuesday, speaking on CBSN. "In a country like Congo, mining is one of the few decently paying jobs to be had there, and so they want to hold onto these jobs."

They also want fair treatment, decent pay, and some safety, "and they would love for their kids to not work in the mines," he said.

"It's a poverty problem," Frankel said. "These parents I talked to – they don't want their kids working in these mines. The problem is that their school fees – schools cost money, and you know, food costs money, and they sort of need their kids to work in there."

Poverty also drives children into the mines instead of school – an estimated 40,000 of them work in brutal conditions starting at very young ages.

The thousands of miners who work in tunnels searching for cobalt in the country "do it because they live in one of the poorest countries in the world, and cobalt is valuable," Frankel wrote in the Washington Post article.

"Not doing enough" 

CBS News spoke with some of the companies that use cobalt in their lithium-ion batteries. All of the companies acknowledged problems with the supply chain, but said they require suppliers to follow responsible sourcing guidelines. Apple, an industry leader in the fight for responsible sourcing, said walking away from the DRC "would do nothing to improve conditions for the people or the environment."

Read company responses here

Amnesty said in November, however, that "major electronics and electric vehicle companies are still not doing enough to stop human rights abuses entering their cobalt supply chains." 

"As demand for rechargeable batteries grows, companies have a responsibility to prove that they are not profiting from the misery of miners working in terrible conditions in the DRC," the organization said. "The energy solutions of the future must not be built on human rights abuses."

An estimated two-thirds of children in the region of the DRC that CBS News visited recently are not in school. They're working in mines instead. 

CBS News' Debora Patta spoke with an 11-year-old boy, Ziki Swaze, who has no idea how to read or write but is an expert in washing cobalt. Every evening, he returns home with a dollar or two to provide for his family.

"I have to go and work there," he told Patta, "because my grandma has a bad leg and she can't."

He said he dreams of going to school, but has always had to work instead.

"I feel very bad because I can see my friends going to school, and I am struggling," he said.

Amnesty says "it is widely recognized internationally that the involvement of children in mining constitutes one of the worst forms of child labour, which governments are required to prohibit and eliminate."

Examples of Lithium Battery Fires

LITHIUM batteries EXPLOSE! So whats next? LITHIUM BOMB!!! .. Misha

[srfirefox]

I used to work in a shop that sold lithium batteries for radio control cars/planes and older batteries were especially prone to this. If you must deal with something like this yourself, fill a heat resistant container - the bigger the better - and fill it with warm water, then dissolve as much salt or baking soda as possible inside. Then weight the lithium cell/battery down into the salty water for a few days.

Water can absorb an incredible amount of heat, which prevents the battery from heating up, and the salt/soda makes the water conductive which will safely release the remainder of the electrochemical energy inside the battery. It's this energy that typically starts a fire when one of these batteries finishes dying.

You'll typically end up with nickel and iron salts in the water, which are typically not dangerous unless you drink them, so don't throw the water down your kitchen drain. Wear vinyl or rubber gloves when you handle the batteries now and toss them in a plastic bag. But the battery/cell will be safe enough to handle until you can get it to a battery disposal if that's not an easy task for you.

Do Lithium Batteries Refill Faster Than Lead-Acid Batteries?

Lithium batteries recharge significantly faster than lead-acid batteries due to their advanced technology and ability to handle higher charge currents efficiently

[brovolt-tech]

What can you do when the battery catches fire? All we can do is watch it burn up. This is a poor quality product. BroVolt insists on high quality products and refuses to use inferior raw materials.

^^^^^

The most fascinating thing about the whole article is the fact that firefighters are evidently continuing to put out lithium fires with water - lithium, the metal that famously ignites in water.

Are we saying that using a gazillion extra gallons of water is the most efficient/safest method here?? This amounts to forcing the lithium to continue burning itself until its fuel (the lithium itself) is exhausted and the chemical reaction is over, coupled with (presumably) a massive amount of insulating water so that things around it don't burn.

Or do firefighters, who are famous for having the knowledge and resources to fight fires, simply not have the resources?? Or ....??? Seriously, what is the deal @ firefighters?? Why are you using water over recommended solutions.

Or is it perhaps the journalists who are the failures here, and they're sensationalizing the status quo practical method for lithium battery fires and refusing to provide context?

Top of the list on a Google search are several sites that give you identical info for how to put out lithium fires:

How to Put Out a Lithium Battery Fire

In the case of a lithium battery fire, there are several ways to extinguish it based on the size and type of battery.

Class D fire extinguishers are effective against lithium-metal battery fires. Lithium-ion battery fires are Class B fires, indicating the presence of flammable liquids, so a standard dry chemical or ABC extinguisher can put them out. Lithium battery fire extinguishers counteract the liquid electrolytes in the battery that create conductive pathways.

Small lithium batteries contain very little lithium, so they can be doused with water. To put out large lithium-ion battery fires, use a foam extinguisher containing CO2, powder graphite, ABC dry chemical, or sodium carbonate.

This is not new or shocking information, and it's taught in every fire extinguisher class.

I KNOW firefighters have access to massive quantities of non-water firefighting chemicals, because this is how chemical fires are put out. Though it is true that often the best/most achievable option is to let the fire run its course.

Whatever the reason, this article is failing to provide all the info.

Oh come on…

[clatterbane]

Also just going to post this little infographic on basic battery safety dealing with Li-ion cells here separately.

Anybody doing any kind of hobby or work stuff involving standalone 18650 lithium cells and similar really needs to know this stuff.

For more safety and lots of other assorted battery info, I also strongly recommend Mooch's YouTube channel, which is chock full of educational videos from an electrical engineer who knows his shit (and also seems to be a really good guy):
