QuantumScape has been working on solid-state batteries for over a decade. However, lithium metal poses some unique challenges that require innovations in cell architecture QuantumScape hopes to achieve this with its new FlexFrame concept.
The FlexFrame concept aims to address various challenges in battery technology. Designed to accommodate expansion and contraction, the new design offers features such as efficient heat dissipation during fast charging and the ability to function with or without external pressure. Unlike traditional designs, FlexFrame splits the tasks of expansion and heat transfer, allowing flexibility in the exterior face of the cell while efficiently conducting heat.
The design combines elements from prismatic and pouch cells, thereby providing manufacturing advantages by utilizing existing industry tools and materials. It allows for conventional stacking and sealing techniques, ensuring mechanical stability at the module level. Additionally, the design optimizes packaging efficiency to enhance energy density, with QuantumScape projecting over 800Wh/L in a planned 5Ah cell, with the potential for improvement in higher-capacity designs.
