Carbon anode material formed from template molecules occluded in a magnesium-substituted aluminophosphate

A new doped carbon material has been prepared from a magnesium-substituted aluminophosphate with occluded organic molecules. The carbon material is mainly composed of microcrystalline graphite and amorphous carbon, and a certain amount of H, N and Al also exist in the material. This carbon material is useful as anode material for lithium secondary batteries. After 15 cycling tests, the carbon material retains a reinsertion capacity of 384 mAh g−1 at a current density of 10 mA g−1. Even at a high current density of 100 mA g−1, the reversible capacity of the carbon material is 185 mAh g−1 after 20 cycling tests.
