Damage to the battery or a short-circuit can cause heat and pressure to build up in the battery. If this reaches a certain level it triggers chemical reactions that generate more heat and pressure, causing a positive-feedback loop. Thermal runaway can quickly spread from one battery to the next, leading to catastrophic explosions and fire. By
Factors that induce thermal runaway of lithium batteries are abnormal operating conditions, namely abuse, short circuit, high rate, high temperature, extrusion, and acupuncture. (Heat release from different reactions inside the battery) (8) Internal short circuit. Internal short circuits often cause self-discharge of lithium-ion batteries, capacity decay, local thermal

Factors contributing to the initiation of thermal runaway. LIBs are primarily composed of four key components: the anode, the cathode, the separator, and the electrolyte . During the discharging process, the electrolyte allows lithium ions to travel from the anode to the cathode and travel backwards during the charging process.
Shutdown separators, electrolyte additives, and safe electrolytes are focusing on enhancing the safety of Lithium-ion batteries while keeping battery function well. The cell-level safety strategies are mainly responsive to excessive conditions in temperature, current, voltage, and internal pressure.
