摘 要：A high-energy-density Li-ion battery with excellent rate capability and long cycle life was fabricated with a Ni-rich layered LiNi0.8Co0.1Mn0.1O2 cathode and Si O-C composite anode. The LiNi0.8Co0.1Mn0.1O2 and Si O-C exhibited excellent electrochemical performance in both half and full cells. Specifically, when integrated into a full cell configuration, a high energy density(280 Wh·kg-1) with excellent rate capability and long cycle life was attained. At 0.5 C, the full cell retained 80% of its initial capacity after 200 charge/discharge cycles, and 60% after 600 cycles, indicating robust structural tolerance for the repeated insertion/extraction of Li+ ions. The rate performance showed that, at high rate of 1 C and 2 C, 96.8% and 93% of the initial capacity were retained, respectively. The results demonstrate strong potential for the development of high energy density Li-ion batteries for practical applications.
