- The trouble with lithium metal is its volatility — it can catch fire on contact with liquid electrolyte or even the air.
- But solid state eliminates that problem because it has no liquid.
In a statement to Axios, Toyota said it will commercialize “sulfide system all-solid batteries” that it hopes will have increased durability and improve the range of electric vehicles in which they are installed.
Venkat Viswanathan, a professor at Carnegie Mellon University speaking to Axios also added that even if Toyota’s first-generation pure electrics do not start with lithium metal anodes, the company clearly is establishing a pathway to get there.
“You need more energy density to bring down the cost,” he said.
An electric car with a lithium metal anode would go about 20% further than current technology, or almost 480 kilometres on a charge, he said.
Just to help you know, the new Chevy Bolt goes 380 kilometres without recharging.
The Mahindra e2o plus offers a claimed normal range of between 95 to 120 kilometres on a single full charge.
