Cover Picture: Interphase design of LiNi0.6Mn0.2Co0.2O2 as positive active material for lithium ion batteries via Al2O3 coatings using magnetron sputtering for improved performance and stability (Batteries & Supercaps 6/2024)

The Front Cover shows how alumina coating deposited on NMC cathode particles by using innovative RF‐magnetron sputtering enhances electrochemical performance structural and thermal stability. The alumina‐coated NMC skier performs much better than uncoated samples in the race for long‐term charge/discharge cycling stability and capacity retention due to effective protection of active material from direct contact with electrolyte and mitigating parasitic side reactions. Moreover, the coated sample showed better structural stability and safety properties. More information can be found in the Research Article by M. Börner and co‐workers (DOI: 10.1002/batt.202300580).
