How Does Lithium-Ion Chemistry Lead to Swollen Batteries?
Lithium-ion chemistry can lead to swollen batteries primarily due to the formation of gas within the battery cells. In these batteries, lithium ions move between the anode and the cathode during charge and discharge cycles. When the battery undergoes stress, such as overcharging or high temperatures, it can cause the electrolyte to decompose. This decomposition leads to the production of gas, which builds up inside the battery casing.
After excess gas accumulates, it creates pressure within the battery. If the pressure exceeds the casing’s limits, it causes the battery to swell. Additionally, internal short circuits can occur, producing heat and exacerbating the gas formation. These processes occur in a cycle, as the swelling can damage the electrodes further, triggering more gas production.
In summary, the swelling of lithium-ion batteries is a result of gas formation due to electrolyte decomposition under stress. This gas builds up pressure, leading to physical swelling of the battery. Understanding this chemistry helps in recognizing the importance of handling battery-operated devices carefully to prevent such issues.
