Anomalous lithium storage in a novel nanonet composed by SnO2nanoparticles and poly(ethylene glycol) chains†
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.
