Front Cover: Mimicking Capacity Degradation in a Lithium Ion Battery Anode in Cells With a Li Metal Electrode: A Perspective on Advantages (Adv. Energy Sustainability Res. 2/2026)

Key Points

• The main goal is to explore capacity degradation in lithium ion battery anodes by examining active lithium loss.
• Analyzes the effects of active lithium loss on charge and discharge cycles.
• Discusses the influence of charge cut-off voltage on capacity variation.
• Examines overvoltage impacts on anode performance.
• Capacity fluctuations occur due to small differences in overvoltage.
• Considering active lithium loss may lead to more stable battery performance.
• Fixed charge cut-off voltage is sensitive to capacity changes.
