Better, Cheaper EV Batteries On The Horizon

Quote:But things are changing. In July of this year, it had developed sodium-ion battery cells with an energy density of 160 Wh/kg. The best lithium-ion cells can store 240 Wh/kg, but LFP cells are close to that 160 Wh/kg figure. CATL says it plans to get the energy density of its sodium batteries up to 200 Wh/kg by the time production begins in 2023. In August, China’s Ministry of Industry and Information Technology said it would prioritize the development, standardization, and commercialization of sodium-ion technology.

Quote:Lithium-sulfur batteries have an energy density of up to 600 Wh/kg — more than double the best available lithium-ion batteries. Imagine what that could mean. Cars with 800 miles of range or more would be possible. That’s good. But Li-S batteries tend to eat their electrodes. That’s bad.
Researchers at the Monash University in Melbourne, Australia think they have solved the problem by adding a tiny dose of sugar to the formula used to make the electrodes for Li-S batteries.
