Synthesis, characterization of core-shell carbon-coated CaSnO3 nanotubes and their performance as anode of lithium ion battery

► We design a strategy to obtain carbon-coated CaSnO3 nanotubes directly via a solvothermal synthesis. ► The uniform carbon-coating layer plays essential roles of a good conductor and a structure buffer. ► It shows enhanced cycling performance in term of cycling stability.
