Li-ion batteries and sodium-ion batteries have the same storage mechanism. Compared with lithium-ion batteries, sodium-ion batteries have the advantages of low cost and abundant sodium sources. However, because the radius of sodium ions (0.102nm) is much larger than the radius of lithium ions (0.076nm), finding a host material that can stably insert/remove sodium ions in the actual application process has become the key to the application of sodium-ion batteries in new energy vehicles. Although metal oxides (cobalt oxide, iron oxide, nickel oxide, etc.) with high theoretical capacity have good application potential in sodium ion cathode materials, sodium ion batteries have poor cycle life due to large volume expansion and low electrical conductivity during the sodium conversion process;While nanostructured metal oxides and their composites (MnO2 nanocrystals, NiO/Ni/ graphene, etc.) can effectively improve the cycle stability, but their durability under high current density is poor. Therefore, it is necessary to further develop the negative electrode material of sodium ion battery with high cycle stability and durability to buffer the problems of volume expansion and conductivity reduction in the sodium conversion process.展开更多
