Manganese silicate was simply fabricated by the reaction between Na2SiO3 center dot 9H(2)O and MnCl2 center dot 4H(2)O. The carbon-coated manganese silicate acting as anode material for lithium storage exhibits outstanding rate performance and high-rate cycling stability. Combining detailed characterizations with electrochemical measurements revealed that the uniform carbon coating around the manganese silicate nanoparticles as conductive material and the formation of lithium silicate as solid electrolyte are responsible for the excellent performance. The carbon-coated manganese silicate could meet the requirement for fast charging/discharging Li-ion batteries. (C) 2015 Elsevier Ltd. All rights reserved.
