With the rapid development of portable and wearable electronic devices,research on flexible energy storage devices has gradually shifted to the directions of miniaturization,softness and intelligence.At the same time,people have higher requirements for the energy density,power density and mechanical properties of the device.As the core part of flexible energy storage devices,electrode material is the key to determining device performance.With the development of flexible energy storage electronic devices,there is an urgent need for new battery technology and fast,low cost and precise control of their microstructure preparation methods.Therefore,the research and development of new energy storage devices such as flexible lithium/sodium-ion batteries,flexible lithium-sulfur batteries,and flexible zinc-air batteries have become the current research hotspots in academia.The current research status of flexible energy storage battery electrodes in recent years was discussed in this paper,the design of flexible electrode materials (independent flexible electrodes and flexible substrate electrodes),and the preparation process of flexible electrode materials of different dimensions(one-dimensional materials,two-dimensional materials and three-dimensional materials) and applications of flexible energy storage electrodes(flexible lithium/sodium ion batteries,flexible lithium-sulfur batteries,flexible zinc-air batteries)were compared and analyzed,and the structural characteristics and electrochemical properties of electrode materials were discussed.Finally,the current problems faced by flexible energy storage devices were pointed out,and the future focus of flexible energy storage devices was the research and development of new solid electrolytes,the rational design of device structures and the continuous optimization of packaging technology. |
