Abstract

Sodium-ion battery is a type of re-chargeable battery which uses sodium-ions as its charge carriers and is very similar to LIBTs in many ways. The measured reversible Sodium ion capacities of GO/Li&Na/GO based anodic materials are considerably improved compared to the conventional graphite-based anodic materials. Graphene oxide has displayed great behavior as suitable materials for anodic sodium ion batteries (LIBs) due to their unique properties. In this study GO sheet has been localized inside the graphene as an option to enhance electrochemical ratio. Moreover, the structure of GO/Li&Na/GO can be to improve the capacities and electrical transport in GO sheets-based LIBs. Therefore, the modification of GO sheet and design of GO/Li&Na/GO structure provide strategies for improving the performance of GO-based anodes. GO/Li&Na/GO could also be assembled into freestanding electrodes without any binder or current collector, which will lead to increased energies density for overall batteries designing. In addition, the relationship among electrical and ionic conduction for three cathode materials including LiCoO2, LiMn2O4, LiFePO4 have been discussed towards phase changing in sodium anodes and how it relates to diffusivity and conductivity and the key conduction issues with some organic liquid and ionic liquid electrolytes.
