The Design of a LiFePO₄/Carbon Nanocomposite With a Core–Shell Structure and Its Synthesis by an In Situ Polymerization Restriction Method

Abstract

Truly long-life: A LiFePO4/carbon composite containing a highly crystalline LiFePO4 core with a size of about 20–40 nm and a semi-graphitic carbon shell with a thickness of about 1–2 nm provides both high power and very long cycling life (see picture). The synthetic method can be extended to the preparation of other materials, such as Li4Ti5O12/carbon and Mn3O4/carbon composites.
