UCLA的dunn教授在science上发表的一篇关于电化学储能的综述 Nature Materials上的最新正极材料研究 摘要：Nickel-rich layered lithium transition-metal oxides, LiNi1−xMxO2 (M = transition metal), have been under intense investigationas high-energy cathode materials for rechargeable lithiumbatteries because of their high specific capacity and relatively low cost1–3. However, the commercial deployment of nickel-rich oxides has been severely hindered by their intrinsic poor thermal stability at the fully charged state and insufficientcycle life, especially at elevated temperatures 1–6. Here, we report a nickel-rich lithium transition-metal oxide with a veryhigh capacity (215 mA h g−1), where the nickel concentration decreases linearly whereas the manganese concentration increases linearly from the centre to the outer layer of each particle. Using this nano-functional full-gradient approach, we are able to harness the high energy density of the nickel-rich core and the high thermal stability and long life of the manganese-rich outer layers. Moreover, the micrometre-size secondary particles of this cathode material are composed of aligned needle-like nanosize primary particles, resulting in a high rate capability. The experimental results suggest that this nano-functional full-gradient cathode material is promising for applications that require high energy, long calendar life and excellent abuse tolerance such as electric vehicles.
