Abstract: Carbon-coated Li 2 MnSiO 4 nanocrystallites are synthesized via a solid state reaction, and their cathode and anode performance is comparatively studied. The Li 2 MnSiO 4 cathode shows an initial charge/discharge capacity of 405/134 mAh g −1 at a current density of 16.6 mA g −1 , and a low charge/discharge capacity of 93/66 mAh g −1 during the 20th cycle. Partial Li 2 MnSiO 4 cathode decomposes at 4.56 V ( vs Li + /Li) during the initial charge. Interestingly, the Li 2 MnSiO 4 anode exhibits a high initial discharge/charge capacity of 658/388 mAh g −1 at a current density of 20 mA g −1 , and a discharge/charge capacity of 459/456 mAh g −1 during the 50th cycle. Li 2 MnSiO 4 anodes also have stable and good rate capabilities. The Li 2 MnSiO 4 crystallites as anode decompose during cycling, and their capacity increases simultaneously. It is proposed that Li 2 MnSiO 4 anode converts energy via a reversible conversion reaction. [ABSTRACT FROM AUTHOR]
