Reaction onset temperature
WebSep 11, 2024 · National Center for Biotechnology Information WebThe onset temperature for the first exothermal reaction for the aged cell is 20°C lower than for the new cell (70 instead of 90°C). This means that under these conditions for this particular cell the SEI layer has lost some of its thermal stability, giving a less safe cell.
