Advanced High Silicone Anode Prismatic Battery Production in California

Project Innovation

The purpose of this Agreement is to fund the build-out of a Low-Rate Initial Production pilot line for silicon anode prismatic batteries with up to 30% greater energy capacity compared to traditional graphite-based technology. These batteries increase the lithium capacity – and therefore energy density - of the anode by alloying lithium with silicon (Si) while still mitigating lifecycle risks that are found in many Si anode technologies by combining Si with oxygen which minimizes the expansion/contraction at the particle level and optimizing the electrode to accommodate expansion during the charge and discharging processes This battery also incorporates a patented internal fuse, increasing the safety of the battery during short-circuit events. During the project, a production line will be built capable of manufacturing 500 cells/day while maintaining 90% yield.
