Abstract
Due to the high demand for more convenient flexible devices, there are more requirements for higher performance of flexible batteries. The layered lithium-rich manganese-based Li1.2Ni0.13Co0.13Mn0.54O2 cathode material has the advantages of higher energy density, higher discharge capacity and environmentally friendly, so it can be used for high-performance flexible electrode cathode material. Its theoretical capacity can reach more than 250mAh g-1, which is higher than most cathode materials currently used in commercialization. Here we synthesize Li1.2Ni0.13Co0.13Mn0.54O2 (LNCM) cathode, and then use a simple method to make a current collect-free LNCM flexible film. This film has excellent flexibility and electrochemical performance. At 25 mA g-1, its initial discharge capacity reaches 314.0 mAh g-1. After 200 cycles of 500 mA g-1, its capacity retention rate is 82.1%, the attenuation is about 0.08% per cycle. Moreover, by bending at any position of the flexible film, it can still remain intact, and the soft-packaged battery made by the flexible film can still be used under the bending condition and keep the brightness of the LED lamp unchanged. This shows that using Li1.2Ni0.13Co0.13Mn0.54O2 to make high-performance flexible electrodes is a simple and effective method, which is expected to be practically applied to flexible electronic devices.Keywords
