Preparation and Properties of All-Solid-State Aqueous Lithium-Ion Batteries Based on Carbon Nanotube Yarns

摘要：

　　High-performance energy storage devices were urgently needed for developing wearable electronic devices.While,how to achieve high flexibility of high-performance energy storage materials has not been solved.Here,we report a fibrous all-solid-state aqueous lithium-ion battery based on carbon nanotube(CNT)yarns and PVA-LiNO3 gel polymer electrolyte(GPE).Carbon nanotubes modified by LiV3O8(LVO/anode)and carbon nanotubes modified by LiMn2O4(LMO/cathode)were prepared by air calcination and the"Biscrolling"method.The results show that the excellent conductivity and physical properties of CNT improved the electrochemical performance of the battery,and the cyclic stability of the battery was significantly improved by using polypyrrole(PPy)coated LVO(LVO@PPy).The capacity retention rate of the battery was up to 90%in 100 cycles,which was nearly 13%higher than the original.It shows that the all-solid-state aqueous lithium-ion battery designed in this experiment has good stability and high efficiency,which provides a potential design strategy for devel-oping energy storage devices for intelligent wearable electronic devices in the future.
