Under an extreme over-discharge condition, the dissolved copper ions deposit on the cathode, anode, and separator, and ultimately the system becomes an electrical wire instead of an electrochemical system, leading to a benign short circuit, making the cell or battery unusable.
Various factors such as high temperatures, overcharging and external impacts can lead to the collapse of the battery''s internal structure. Structural failure of the battery may result in internal short circuits, which in turn can cause rapid temperature increases and potentially lead to thermal runaway, even resulting in fires and explosions [4].
