Title: Tin-containing anode materials in combination with Li{sub 2.6}Co{sub 0.4}N for irreversibility compensation

Abstract

High irreversible capacities in the first cycle hinder potential applications of SnO and ultrafine SnSb{sub 0.14} hosts as anode materials in lithium-ion batteries. This deterrent can be overcome by introducing lithium transition metal nitrides such as Li{sub 2.6}Co{sub 0.4}N into the electrodes based on the above hosts. Li-rich Li{sub 2.6}Co{sub 0.4}N offers an additional lithium source for the electrode and can completely compensate the first irreversible capacity. The first cycle efficiency is adjustable by controlling the ratio of Li{sub 2.6}Co{sub 0.4}N to another host (SnSb{sub 0.14} or SnO) in the electrode. The tin-containing hosts are compatible with Li{sub 2.6}Co{sub 0.4}N in an electrolyte of 1 M LiClO{sub 4}/ethylene carbonate-diethyl carbonate (EC + DEC) (1:1). Owing to a small volume change of the Li{sub 2.6}Co{sub 0.4}N structure, its dispersion in a SnSb{sub 0.14} host can also buffer the electrode volume effect and, thereby, improve the cyclability.
