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

Invited for this month's cover picture is the group of Markus Börner at MEET Battery Research Center from the University of Münster. The cover picture depicts skiers (NMC active material) competing in a skiing race (electrochemical stability). RF‐magnetron‐based homogenously coated NMC outperformed inhomogeneously coated and uncoated ones due to better protection.
