Abstract

A series of PEG–SnO₂ nanocomposites has been investigated as anode materials for lithium batteries. They exhibited an unexpectedly high lithium storage over the theoretical capacity of SnO₂. The origin of such extra capacity cannot be interpreted by the conventional lithium storage mechanisms of anode materials.
