Abstrakt: A conformal Mg(OH) 2 nanoshell was constructed through a wet-chemical process, where a gradual release of OH - as the precipitating agent was designed to ensure the heterogeneous growth of the coating species. Such a coating treatment was found to be efficient in improving the structural stability and electrochemical stability of a 5 V LiNi 0.5 Mn 1.5 O 4 cathode.
