Understanding the Degradation Mechanisms of Lithium-Ion Battery Materials
Lithium-ion batteries power 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 factor 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 important mechanism is the dissolution of cathode materials into the electrolyte, often triggered by overcharging or high operating temperatures. This phenomenon can result 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 creation of unwanted byproducts that contribute to capacity fade and probable safety risks.
Understanding these degradation mechanisms is essential for developing strategies to enhance battery life and safety. Research efforts are focused on investigating new materials, electrolytes, and configurations that can mitigate these degradation processes.
