Ultra‐long cycle life and high rate performance subglobose Na3V2(PO4)2F3@C cathode and its regulation

Summary A nitrogen‐doped carbon coated subglobose Na3V2(PO4)2F3@C (NVPF) cathode for sodium‐ion batteries was synthesized by using hexadecyl trimethyl ammonium bromide (CTAB) as soft template and polyvinylidene fluoride (PVDF) as carbon source. CTAB plays a significant role on the formation of spher...
