They probably tested it with the nail-puncture test.
If they can poke a hole in it and it doesn’t explode, that’s pretty safe.
Main components of LMFP batteries are: Lithium, Manganese, Iron, Phosphate, and Graphite. Compared to Sulfuric Acid, Lead and Cadmium for conventional or older technology rechargeable batteries, and you can easily see which one is less toxic for the environment.

rofl lmao 😀 gooooood point 🤣 can’t agree more 🤣 😛

How did Toyota claim bz4x can run 400km when it’s wheels are prone to fall off before you even reach that distance? 🤣🤪

How can a battery be claimed as safe when it has just been unveiled?

How did Toyota claim bz4x can run 400km when it just unveiled? 😛 oh i forgot, once an illiterate always an illiterate

🤣🤣🤣

Japanese Toshiba and Panasonic making batteries for decades are actually good for environment, and millions of cells disposed in trash turns into seeds then grow into green trees 😛 u should know that

“As CATL’s third-generation CTP battery, Qilin incorporates liquid cooling to increase the heat transfer area by four times, cutting thermal control time in half and supporting a hot start in 5 minutes and fast charging in only 10 minutes. This cooling structure also allows the cell to rapidly cool down in extreme circumstances, helping to prevent abnormal thermal conduction among the cells and achieving thermal stability and safety for all the battery’s chemical systems, making it compatible with materials with higher energy density.”

“This makes the Qilin battery safer and more durable than many existing battery cells. The Qilin is also 13% more powerful than Tesla’s upcoming new 4680 battery technology, and has the longest range offered by any mainstream manufacturer yet.”

That is how! It has been explained very clearly. The companies also do their full research on these batteries before the launch.

As for impacts of batteries:

https://cleantechnica.com/2021/10/12/catl-plans-5-billion-battery-recycling-factory/

Here are some pertinent points from the article linked above:

“CATL, China’s largest battery manufacturer, has announced it intends to invest $5 billion in a battery recycling factory to be located in Yichang, a city in Hubei Province which is in central China. The new factory will recycle used battery materials and produce materials including lithium iron phosphate, lithium cobaltate, and cathode materials such as graphite and phosphoric acid.

Chinese law imposes a duty on battery manufacturers to be responsible for recycling their products when they reach the end of their useful life. According to China EV Post, the project aims to meet its demand for capacity expansion of power batteries, secure the supply of battery materials, and advance the company’s goal of full life-cycle management of retired power batteries. That number is expected to rise to almost 800,000 tons by 2025, according to Central China Television.”

“…the ecological impact of EV batteries is greater than normal car’s battery…”

Here are some highlights:

“Lead-acid batteries typically last only about two years in warmer climates, said Fuller, as heat causes them to degrade more quickly, meaning they need to be recycled frequently. However, there are few facilities that can safely do this in Africa.
Instead, these batteries are often cracked open and melted down in back yards. The process exposes the recyclers and their surroundings to lead, a potent neurotoxin that has no known safe level and can damage brain development in children.
Lithium-ion batteries could offer a less toxic and longer-lasting alternative for energy storage, Fuller said.”

And just to cover the point, because I know your mind will go in that direction, the Japs are just as involved in the pollution caused by the lead acid batteries as anyone else because they have been using them for decades as well.

Maybe read the stuff this time… Please! 🤷‍♂️

Cut-throat pace of technology indeed.
