Amorphous Carbon-Coated Tin Anode Material for Lithium Secondary Battery

Abstract

A uniform amorphous carbon coating on the tin nanoparticles was prepared from aqueous glucose solutions using a hydrothermal method at 180 °C, which facilitated an enhanced dimensional stability during Li alloying/dealloying. This material showed excellent initial capacity and capacity retention, 681 mAh/g and 98% retention after 50 cycles, respectively.
