Understanding the Degradation Mechanisms of Lithium-Ion Battery Materials
Lithium-ion batteries fuel a vast array of electronic devices due to their high energy density and relatively long cycle life. However, these batteries are susceptible to degradation mechanisms that can reduce their performance over time.
One major factor to degradation is the formation of solid-electrolyte interphase (SEI) layers on the anode surface. This SEI layer operates as a protective barrier but also consumes lithium ions and increases resistance, leading to capacity loss.
Another crucial mechanism is the dissolution of cathode materials into the electrolyte, often initiated by overcharging or high operating temperatures. This phenomenon can result the formation of harmful deposits on the electrodes, further hindering battery performance.
Furthermore, side reactions between the electrolyte and the electrode materials can happen, leading to the generation of unwanted byproducts that contribute to capacity fade and potential safety risks.
