Extended Data Fig. 2: Internal short circuiting of liquid-electrolyte graphite/NCM811 LiBs at various state of charge (SOC).
From: Metrics for evaluating safe electrolytes in energy-dense lithium batteries
a, Temporal variations of voltage, shorting current, shorting resistance and internal temperature at 100%, 65% and 50% SOC, respectively. b, Photographic images of LiB cells after ISC. The 100% and 65% SOC cells catch fires due to sufficient heat generated from electrolyte oxidation. In contrast, the 50% SOC cell, generating only half of reaction heat from electrolyte oxidation, emits light smokes only.
