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 diminish 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 operates as a protective barrier but also consumes lithium ions and increases resistance, leading more info 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 generate the formation of harmful deposits on the electrodes, further impairing battery performance.
Furthermore, side reactions between the electrolyte and the electrode materials can occur, leading to the production of unwanted byproducts that contribute to capacity fade and probable safety risks.
Understanding these degradation mechanisms is essential for developing strategies to improve battery life and safety. Research efforts are focused on investigating new materials, electrolytes, and configurations that can mitigate these degradation processes.
