Abstract
⺠The thermal behavior of a nano-LixSi anode in electrolytes has been investigated. ⺠The thermal runaway is delayed by â¼50 °C in the presence of FEC and VC additives. ⺠We identified two mechanisms of LixSi protection by the additives during heating. ⺠FEC and VC electrochemically generate a thermally stable SEI covering the LixSi. ⺠A robust “secondary SEI” is formed by thermal degradation of FEC and VC.
