'Semi-solid state' batteries could lead to cheaper, longer-range EVs
The race to create cheaper, longer-lasting batteries just got more interesting. 24M, a US Department of Energy-funded startup, announced that it has delivered semi-solid state lithium-ion batteries with energy density levels of 250 watt-hours per kilogram (Wh/kg). That roughly matches Tesla's 2170 cells used in the Model 3, considered to be the most efficient cells around. The company thinks it could do even better, making EVs longer lasting, lighter and cheaper.
