High-Performance Dual-Ion Battery Based on a Layered Tin Disulfide Anode.

ABSTRACT: Energy issues have attracted great concern worldwide. Developing new energy has been the main choice, and the exploitation of the electrochemical energy storage devices plays an important role. Herein, a high-performance dual-ion battery system is proposed, which consists of a graphite cathode and SnS₂ anode, with a high-concentration lithium salt electrolyte (4 M LiTFSI). The benefits from the typical sandwich-like layer structure of SnS₂ are as follows: the highest discharge specific capacity of the battery could reach 130.0 mA h g^-1 at a current density of 100 mA g^-1, and even under an ultra-high current density of 2000 mA g^-1, the highest capacity of 66.3 mA h g^-1 is still achieved, with an outstanding capacity retention
