Transition metal crosstalk in conventional graphite-based batteries and advanced silicon-based batteries

Abstract

Crosstalk is known to have a significant impact on the cell performance of batteries due to its effect on safety, cycle life, and calendar life. The mechanism and the effects of crosstalk have been investigated in graphite-based batteries. However, with the increasing demand for batteries with high energy densities, graphite anode is being gradually replaced by silicon-based anodes. Therefore, there is an urgent need to understand crosstalk in silicon-based batteries. Herein, we have provided a comprehensive review of crosstalk behavior in conventional graphite-based batteries and advanced silicon-based batteries. This paper discusses the mechanism of transition metal-ion crosstalk and its effect on graphite-based and silicon-based batteries.
