Copper dissolution refers to the undesirable electrochemical reaction in lithium-ion batteries where copper from the anode current collector dissolves into the electrolyte, typically during over-discharge or low-voltage abuse conditions.
Prevention Strategies:
Robust BMS protection to avoid deep discharge
Safe SoC storage windows (e.g., >20%)
Anode coatings or alternative current collectors (e.g., carbon-coated copper)
Cell design with anti-overdischarge protection fuses or circuits
