As they do so, the electrons that were paired with them in the anode during the charging process are released. These electrons power an external circuit.
Electrolysis: make the current through the electrolyte solution at the anode and cathode cause REDOX reaction process.
电解：使电流通过电解质溶液而在阳极，阴极引起氧化还原反应的过程。

The anode and cathode materials, electrolyte and its additives, structure of battery and manufacture process had important effect on the safety of Li-ion battery.
