Superior Performances of B-doped LiNi(0.84)Co(0.10)Mn(0.06)O(2) cathode for advanced LIBs

Boron-doped Ni-rich LiNi(0.84)Co(0.10)Mn(0.06)O(2) (B-NCM) cathode material is prepared and its electrochemical performances are investigated. The structural properties indicate that the incorporation of boron leads to highly-ordered layered structure and low cation disordering. All samples have hig...

Sumario:Boron-doped Ni-rich LiNi(0.84)Co(0.10)Mn(0.06)O(2) (B-NCM) cathode material is prepared and its electrochemical performances are investigated. The structural properties indicate that the incorporation of boron leads to highly-ordered layered structure and low cation disordering. All samples have high areal loadings of active materials (approximately 14.6 mg/cm(2)) that meets the requirement for commercialization. Among them, the 1.0 wt% boron-doped NCM (1.0B-NCM) shows the best electrochemical performances. The 1.0B-NCM delivers a discharge capacity of 205. 3 mAh g(−1), cyclability of 93.1% after 50 cycles at 0.5 C and rate capability of 87.5% at 2 C. As a result, we can conclude that the 1.0B-NCM cathode can be regarded as a promising candidate for the next-generation lithium ion batteries.
