The heat triggers chemical reactions within the battery, which generate even more heat in a feedback loop. If this heat is not effectively dissipated, the cycle continues, leading to catastrophic failure. In lithium-ion batteries, thermal runaway is especially concerning because of the highly reactive nature of lithium.
And, because plating and stripping can happen quickly on an even surface, the battery can recharge in only about 10 minutes. The researchers built a postage stamp-sized pouch cell version of the battery, which is 10 to 20 times larger than the coin cell made in most university labs.
If not contained, this energy can cause the battery to vent, ignite, or explode. In a battery pack, this heat can propagate to neighbouring cells, leading to a cascading failure known as thermal propagation.
High Discharge Rates: Operating a battery at high discharge rates generates more heat, especially in high-power applications like electric vehicles or drones. If the heat exceeds the battery’s capacity to dissipate it, thermal runaway may occur.
Resistance to Charge Transfer: this resistance can also generate heat during charge and discharge processes, Occurring at the interface between the electrolyte solution and the electrode materials. Electric Resistance within Battery Components: This resistance is intrinsic to various battery parts and contributes to heat generation.
Batteries with larger capacities (Q bat) generally exhibit lower resistance, and the battery capacity influences the duration of heating. In addition, the specific heat affects the rate at which temperature increases, influencing the heating duration, as represented in Eq. (5).
