From electrode saturation to structural collapse: unraveling the rollover failure in a lithium-rich manganese/graphite pouch cell at elevated temperature

Key Points

This research aims to uncover the failure mechanisms in lithium-rich batteries operating under high temperatures.
Investigated failure mechanisms in medium-voltage lithium-rich batteries
Analyzed the impact of electrode saturation on Li plating
Examined the interactions between transition metals in the cells
Identified electrode saturation as a trigger for Li plating
Revealed degradation cascade linked to transition-metal crosstalk
Documented catastrophic capacity rollover in high-temperature conditions

Abstract

The failure mechanism of medium-voltage Li-rich batteries at elevated temperature is unveiled: electrode saturation triggers Li plating and transition-metal crosstalk, forming a degradation cascade that leads to catastrophic capacity rollover.
