Influence of Mo addition on the structural and electrochemical performance of Ni-rich cathode material for lithium-ion batteries

Molybdenum modified LiNi(0.84)Co(0.11)Mn(0.05)O(2) cathode with different doping concentrations (0–5 wt.%) is successfully prepared and its electrochemical performances are investigated. It is demonstrated that molybdenum in LiNi(0.84)Co(0.11)Mn(0.05)O(2) has a positive effect on structural stabilit...

description Molybdenum modified LiNi(0.84)Co(0.11)Mn(0.05)O(2) cathode with different doping concentrations (0–5 wt.%) is successfully prepared and its electrochemical performances are investigated. It is demonstrated that molybdenum in LiNi(0.84)Co(0.11)Mn(0.05)O(2) has a positive effect on structural stability and extraordinary electrochemical performances, including improved long-term cycling and high-rate capability. Among all samples, the 1 wt. % molybdenum LiNi(0.84)Co(0.11)Mn(0.05)O(2) delivers superior initial discharge capacity of 205 mAh g(−1) (0.1 C), cycling stability of 89.5% (0.5 C) and rate capability of 165 mAh g(−1) (2 C) compared to those of others. Therefore, we can conclude that the 1 wt. % molybdenum is an effective strategy for Ni-rich LiNi(0.84)Co(0.11)Mn(0.05)O(2) cathode used in lithium ion batteries.
