SnO2/α-MoO3 core-shell nanobelts and their extraordinarily high reversible capacity as lithium-ion battery anodes†
Abstract
Extraordinarily high reversible capacity of lithium-ion battery anodes is realized from SnO2/α-MoO3 core-shell nanobelts. The reversible capacity is much higher than traditional theoretical results. Such behavior is attributed to α-MoO3 that makes extra Li2O reversibly convert to Li+.
