摘要：

Porous Li1.2Ni0.32Co0.04Mn0.44O2 nanofibers (LNCM-F) were prepared via electrospinning and subsequent annealing process, and then employed as a cathode material for lithium-ion batteries. This porous architecture with interconnected networks offers more electrochemical active sites and shortens electron/ion transfer distance, thus facilitating rapid electron/ion transport during the charge/discharge process. Furthermore, the excellent structural stability of the porous networks significantly contributes to the alleviation of volume change upon cycling. Consequently, LNCM-F cathode delivers a high discharge capacity of 146 mAh g-1 at 0.5 C after 100 cycles.
