Why Does Extreme Temperature Lead to Swelling in Lithium Ion Batteries?
Extreme temperature leads to swelling in lithium-ion batteries due to chemical reactions that occur within the cells. When exposed to high heat, the battery’s internal components can break down, leading to the generation of gas and subsequent swelling.
According to the U.S. Department of Energy, lithium-ion batteries rely on a combination of lithium salts, which allow lithium ions to move between electrodes during charging and discharging. When the temperature rises excessively, these chemical components may react in unexpected ways, causing the batteries to swell.
The primary cause of swelling is gas generation from the decomposition of electrolyte and other materials. This gas builds up inside the battery and creates pressure. The extreme temperatures can accelerate side reactions that produce gas, ultimately compromising the battery’s integrity. Notably, this process can also lead to thermal runaway, a severe condition where the battery’s temperature and pressure increase uncontrollably.
Thermal runaway occurs when the battery’s temperature exceeds a specific threshold, often above 60 degrees Celsius (140 degrees Fahrenheit). At high temperatures, the electrolyte, which is a conductive liquid allowing ion movement, decomposes and produces gases like carbon dioxide and methane. This results in swelling and can, in severe cases, lead to leakage or even combustion of the battery.
Specific conditions that contribute to swelling include:
- Overcharging: Charging the battery beyond its rated capacity can generate heat.
- Poor ventilation: Insufficient airflow around the battery can trap heat.
