Li3V2(PO4)(3)/C　positive　material　was　synthesized　via　a　one-step　solid-state　reaction　route　using　humic　acid　as　both　reduction　agent　and　carbon　source.　The　SEM　image　shows　that　the　particles　merge　with　each　other　to　form　a　porous　structure.　This　microstructure　helps　the　electrolyte　to　penetrate　the　positive　materials　and　promotes　good　electronic　contact　among　Li3V2(PO4)(3)　Particles.　Electrochemical　tests　display　that　the　Li3V2(PO4)(3)/C　positive　material　reaches　an　initial　discharge　capacity　of　131.2　mA　h　g(-1)　at　0.2　C　and　exhibits　a　good　cyclic　performance　at　3　C　charge/discharge　rates　in　the　range　of　3.0-4.3　V.　The　results　indicate　that　the　one-step　solid-state　reaction　is　a　promising　method　suitable　for　mass　production　of　Li3V2(PO4)(3)/C　material　with　high　electrochemical　performance.　(C)　2008　Elsevier　Ltd.　All　rights　reserved.
