that is at least a third higher. In July 2024, VW PowerCo and QS announced an agreement for volume production. The initial goal is 40 gigawatt-hours’ worth of batteries per year. In October 2024, QuantumScape introduced a prototype of their first planned commercial product they are calling QSE-5. The QSE-5 B-sample cell has a measured cell energy of 21.6 Watt-hours (Wh) at C/5 discharge rate and 25 °C. This is divided by the cell volume to get the ''volumetric energy density'' of 844 Wh/L or by the cell mass to get the ''gravimetric energy density'' (also called ''specific energy'') of 301 Wh/kg.
