Sandwich-like Cr2O3–graphite intercalation composites as high-stability anode materials for lithium-ion batteries†
Abstract
Novel sandwich-like Cr2O3–graphite intercalation composites (Cr2O3–GICs) were synthesized via an intercalation–transformation method. Cr2O3 nanoparticles (NPs) are intercalated between the adjacent carbon layers of graphite and tightly immobilized. The Cr2O3–GICs show promising performance as anode materials for LIBs with a reversible capacity of about 480 mA h g−1 and a relatively low lithium insertion potential. More importantly, the Cr2O3–GICs demonstrate an extremely promising stable cycling performance with over 100% capacity retention after 1000 cycles. Furthermore, the intercalation–transformation method also provides another fabrication method of graphene-based assembled materials.
