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 contributor to degradation is the formation of solid-electrolyte interphase (SEI) layers on the anode surface. This SEI layer functions 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 occur, leading to the generation of unwanted byproducts that contribute to capacity fade and probable safety risks.
Understanding these degradation mechanisms is critical for developing strategies to enhance battery life and security. Research efforts are focused on exploring new materials, electrolytes, and architectures that can reduce these degradation processes.
