Fluorine atom-inducing graphene oxide in situ coating SnPO compo...

With the development of society, rechargeable batteries are becoming ever-popular in people's lives..Although rechargeable sodium-ion batteries have attracted a large number of researchers, they suffer.from the limited cycle stability and low capacity. To address these issues, tin-phosphorus-oxygen (SnPO).composite materials were protected by the curling of reduced graphene oxide (rGO) induced by the.fluorine atoms from the electrolyte. The in-situ coating protection not only can increase the el
