“…Although LIB technologies made remarkable progress in the past few years, the capacity of these batteries is limited by the use of graphite as the anode material, leading to a low capacity and energy density. Researchers have widely investigated the use of new anode materials in LIBs, such as carbon‐based materials (carbon nanofibers (CNFs), carbon nanotubes, carbon nanospheres, graphene, and their heteroatom modifications), transition metal oxides (SnO 2 , Cr 2 O 3 , V 2 O 5 , ZnO, and TiO 2 ), and transition metal sulfides (FeS 2 , NiS, CoS, MoS 2 , and SnS 2 ). However, with the economic development and the gradual depletion of lithium resources, lithium has become an expensive element 2a,4.…”
