Improving long-term cyclic performance of LiNi0.8Co0.15Al0.05O2 cathode by introducing a film forming additive Layered structure Ni-rich LiNi0.8Co0.15Al0.05O2 cathode has been considered as a higher energy density candidate, but the problems of poor interface stability and cyclic performance restrain its further application. Herein, a functional vinyl (eC]Ce) group allylboronic acid pinacol ester (ABAPE) is introduced as a film forming additive.
