文摘

In this paper mesoporous SnO₂ nanospheres with an average diameter of about 83 nm, composed of many tiny primary particles (?0 nm) and holes, are synthesized on a large scale by a simple hydrothermal route. The as-prepared mesoporous SnO₂ nanospheres were uniformly coated with carbon by a further hydrothermal treatment in glucose aqueous solution. As anode materials for lithium-ion batteries, the core-shell SnO₂/C nanocomposites exhibit a markedly improved cycling performance.
