The protective properties of the coating applied to the surface of lithium-manganese spinel (LiMn2O4), using the eutectic composition of Li2O : B2O3 = 47 : 53 (wt.) with the melting point of 650°C, were studied. The content of the eutectic lithium borate varied from 1% to 10%. The electrochemical behavior of the obtained materials in the cathode half-cells of lithium-ion battery was studied at room temperature.
