The electrochemical behavior of lithium-ion battery positive electrode material LiNi1/3Mn1/3Co1/3O2 solid solution with surface protective layer of amorphous lithium borate has been studied. An optimal lithium borate content of 1 wt% has been found to enable stable cycling at 0.5C rate with maximum discharge capacity.
The electrochemical behavior of layer-structure LiNi1/3Mn1/3Co1/3O2 solid solution, a positive electrode material of lithium-ion battery, with surface protective layer of amorphous lithium borate is studied. The protective coating is prepared by the eutectic incongruent melting at 750 degrees C of a pre-synthesized compound Li3BO3, mechanically mixed with LiNi1/3Mn1/3Co1/3O2 powder. The glassy lithium borate 3Li(2)O center dot B2O3 is found to form island-like structures presumably localized in electrochemically active regions of the active-material particles' surface. The optimal lithium borate content, which makes possible the LiNi1/3Mn1/3Co1/3O2 stable cycling at 0.5 C rate with the maximum discharge capacity, is found to be equal to 1 wt %.
