Initial Coulombic efficiency improvement of the Li1.2Mn0.567Ni0.166Co0.067O2 lithium-rich material by ruthenium substitution for manganese

Abstract

The initial Coulombic efficiencies of the Li_1.2Mn_0.567Ni_0.166Co_0.067O₂ lithium-rich material are largely improved by ruthenium substitution for manganese, and the highest value is about 86% with 284 mA h g⁻¹ initial discharge capacity at room temperature when the content of substituted ruthenium is 5 mol%.
