Truly long‐life : A LiFePO 4 /carbon composite containing a highly crystalline LiFePO 4 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 Li 4 Ti 5 O 12 /carbon and Mn 3 O 4 /carbon composites.
