摘要
The rapid development of sodium-ion batteries (SIBs)requires the search for high-performance electrode materials with high energy density. In this regard, free-standing electrode materials without additional conductive agents,adhesives and metal foil current collectors can effectively reduce the overall electrode mass, thereby increasing the energy density.
