文摘

Embedded battery sensors critical for accurate cell state, safer/fuller utilization. Value of internal cell signals obtained with fiber-optic (FO) sensors demonstrated. Intercalation strain and electrode temperature key cell parameters monitored. Advanced algorithms enable <2.5% accurate cell state estimation with FO signals.
