Double‐shelled nanostructure of SnO2@C tube‐in‐SnO2@C tube boosts lithium‐ion storage

In the case of SnO 2 -based lithium-ion battery anodes, the double-shelled hollow nanostructures are expected to possess better performances than their single-shelled counterparts, but the fabrication of double-shelled hollow nanostructures is more difficult than those with single shell because of t...
