Title: Effect of formation protocol: Cells containing Si-Graphite composite electrodes

Abstract

The effect of formation protocol was observed in tests using small pouch cells containing silicon-graphite/Li(Ni 0.5Mn 0.3Co 0.2)O 2 chemistry. The time for the formation protocol was either 13.2 or 186 h for the tested cells. It is demonstrated that the “fast” formation protocol produces cells with similar performance characteristics to that of the “slow” protocol. Moreover, the solid-electrolyte interface layers from both formation protocols are stable and function analogously, albeit with different chemistry. The fast formation protocol may thus allow a more economical route to cell fabrication.
