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 impact their performance over time.
One major cause to degradation is the formation of solid-electrolyte interphase (SEI) layers on the anode surface. This SEI layer acts as a protective barrier but also consumes lithium ions and increases resistance, leading to capacity loss.
Another essential mechanism is the dissolution of cathode materials into the electrolyte, often initiated by overcharging or high operating temperatures. This phenomenon can generate the formation of harmful deposits on the electrodes, further compromising battery performance.
Furthermore, side reactions between the electrolyte and the electrode materials can take place, leading to the production of unwanted byproducts that contribute to capacity fade and possible safety risks.
Understanding these degradation mechanisms is essential for developing strategies to optimize battery life and safety. Research efforts are focused on exploring new materials, electrolytes, and architectures that can reduce these degradation processes.
