VIDEO: QuantumScape's FlexFrame EV Battery Cell

QuantumScape's EV battery has gotten recent headlines for its promising VW test results. The company has now released a video that provides a detailed look at its proprietary FlexFrame battery cell architecture. The company explains that the FlexFrame format is a hybrid of conventional pouch and prismatic cell designs that was engineered to address the expansion of lithium metal as it plates and strips during charging and discharging. This design maximizes the performance of solid-state lithium metal batteries, which promise higher energy density, faster charging and enhanced safety compared to today’s lithium-ion batteries. FlexFrame also has manufacturing benefits, as it is able to leverage many tools and materials already available in the battery landscape. The flexible interface, paired with the frame design, enables the easy stacking of batteries into modules for automotive and other applications.
