Here’s the battery pack behind VW’s global electric-vehicle push
Volkswagen credited its anticipated rapid evolution of lithium-ion cells for its impressive energy-to-weight numbers in its new packs. Volkswagen estimates that cell energy density—both by volume and weight—will increase nearly a quarter from 2018 to 2025. The potential of solid-state cells, around 2030 or a bit later, could boost energy density (by volume) by another 25 percent, to 1 kwh per liter from a current level of about 0.650 kwh per liter.
“The use of solid-state batteries may result in another breakthrough in the second half of the next decade,” said Thomas Ulbrich, the member of the Volkswagen Group board of management for e-mobility, in an introduction. Ulbrich mentioned Volkswagen’s joint-venture development of solid-state tech with QuantumScape, and said that a limited fleet test of vehicles with solid-state cells could begin as soon as 2023.
