Terms for Batteries Over discharge: Definition:during discharge,if the battery continues to discharge even beyond the discharge voltage limit the reversibility of both electrode materials will be damaged,leading to a decreased battery capacity Overcharge: Definition:during charge,if the battery continues to charge even after the capacity is full,the battery would likely to suffer from deformation or electrolyte leakage with a significantly deteriorated performance. 44 Terms for Batteries • Over discharge: • Definition: during discharge, if the battery continues to discharge even beyond the discharge voltage limit, the reversibility of both electrode materials will be damaged, leading to a decreased battery capacity . • Overcharge: • Definition: during charge, if the battery continues to charge even after the capacity is full, the battery would likely to suffer from deformation or electrolyte leakage with a significantly deteriorated performance
