In　the　present　work,　Li2MnO3　nanowires　with　a　good　electrochemical　performance　were　synthesized　by　a　simple　molten-salt　method,　at　a　low　temperature,　using　Mn2O3　nanowires　with　MnF2　as　the　Mn　source.　The　discharge　capacity　of　the　Li2MnO3　nanowires　used　as　the　cathode　material　in　a　lithium-ion　battery　was　up　to　159.8　mA　h　g(-1)　after　27　cycles　in　a　voltage　range　of　2.0　to　4.8　V　at　a　current　density　of　20　mA　g(-1)　at　room　temperature.　They　also　displayed　a　good　cycling　stability　and　rate　performance　at　different　current　densities.
