Abstract

The common high-capacity cathode Li2C6O6 shows poor cycling performance because of its dissolution in electrolytes. Using morphology control, spherical Li2C6O6 was prepared, and then combined with reduced graphene oxide and modified with an FeF3 coating. This interface engineering inhibited the dissolution of Li2C6O6, and also enhanced its cycling and rate performance.
