This review collects various studies on the origin and management of heat generation in lithium-ion batteries (LIBs). It identifies factors such as internal resistance, electrochemical reactions, side reactions, and external factors like overcharging and high temperatures as contributors to heat generation.
Heat is generated in the battery through the movement of lithium ions from the cathode to the anode, resulting in a sequence of chemical reactions within the battery that produce heat.
