Abstract Developing high-energy and high-power lithium-ion batteries represents the key challenge for electric vehicles. In this work, Ni-rich LiNi0.88Mn0.06Co0.06O2 particles were synthesized by a facile co-precipitation method and interwoven by carbon fiber network (CF-NMC) as the cathode in lithium batteries. The CF-NMC material demonstrated superior electrochemical performance, relative to the pristine NMC, with an exceptional specific capacity of 210 mA h/g at 0.2 C and rate capability of 137 mA h/g and 95 mA h/g at 10 C and 20 C, respectively. These results not only provide further insights into the reaction mechanism but also illustrate a rational direction to synthesize practical Ni-rich cathode materials for Li-ion batteries and improve their high-power performance.
