Overlithiation of LiNi_0.8Co_0.2O₂ for Increased Performance in Li-Ion Batteries

Abstract:

Layered LiNi_1-xCo_xO₂is one of the promising cathode materials for Li-ion battery application. However, the Ni rich cathode materials exhibit low capacity and bad capacity retention. This is due to factors such as disorder and structural instability when Li is removed during charge-discharge. Overlithiation of cathode materials is expected to improve the cation ordering and structural stability. Good cation ordering will increase the battery capacity. During charge-discharge, the irreversible Li⁺ loss can be replaced to a certain extent by the interstitial Li⁺ ions in the lattice of the Li_xNi_0.8Co_0.2O₂material. This helps reduce capacity fading of the cathode materials. In this work the overlithiation of LiNi_0.8Co_0.2O₂ is done by interstitially doping Li⁺in the LiNi_0.8Co_0.2O₂ materials producing Li_1.05Ni_0.8Co_0.2O₂and Li_1.1Ni_0.8Co_0.2O₂. Results showthat the performance of the overlithiated LiNi_0.8Co_0.2O₂materials is better than pure LiNi_0.8Co_0.2O₂.
