Solid state batteries: will they change the world?

Solid state batteries promise 2x higher energy density than traditional lithium ion, with 3x faster charging and lower risk of fires. They could re-shape global energy, especially heavy trucks. But the industry has been marooned by uncontrollable cell degradation. QuantumScape’s disclosures suggest it is light years ahead. But costs may remain high.

Electric vehicle: battery life?

Electric vehicle battery life will realistically need to reach 1,500 cycles for the average passenger vehicle, 2,000-3,000 cycles after reflecting a margin of safety for real-world statistical distributions, and 3,000-6,000 cycles for higher-use commercial vehicles. This means lithium ion batteries may be harder to displace with novel chemistries?

Lithium ion batteries: energy density?

Today’s lithium ion batteries have an energy density of 200-300 Wh/kg. I.e., they contain 4kg of material per kWh of energy storage. Technology gains can see lithium ion batteries’ energy densities doubling to 500Wh/kg in the 2030s, trebling to 750 Wh/kg by the 2040s, and the best possible energy densities are around 1,250 Wh/kg. This…
