AbstractThe key to solving pulverization and stripping from collector caused by volume expansion of high performance electrode lies in the preparation of flexible electrode, which has excellent interface structure and electron/ion mass transfer capacity. A unique process has been used to prepare high-performance transition metal oxide (nickel oxide) coupled carbon fiber mat flexible electrode, which can be directly applied for lithium-ion battery assembly. Due to the high theoretical specific capacitance of nickel oxide, unique low dimensional characteristics and large draw ratios for internal stress dispersion of carbon fiber mat, NiO carbon nanofiber (NiO-CNF) delivers excellent cyclic characteristic and better rate electrochemical performance, which is simultaneously much higher than NiO nanofiber (NiO NF) without carbon. NiO-CNF and NiO NF have reversible capacities of 418 mAh.g(-1) and 242 mA.g(-1) after 200 cycles at 0.5C, respectively. These electrochemical properties can be attributed to diffusion kinetics and external stress buffering provided by the cross-linked structures.
