Fisker Flexible Solid-State Battery will be faster charging, safer and enable more range and costs of less than $100 per kWh.

Fisker's new solid-state batteries use thin-film technology that have been used to make solar cells. Using a new manufacturing process, Fisker says several thin film layers are stacked inside each battery cell, giving them 27 times more surface area than conventional cells. The result is a battery cell with twice as much energy density as a conventional lithium-ion cell. The new cells will last for "well over 1,000" charge cycles.
