Abstract: A lithium ion battery includes a negative electrode, a positive electrode, an separator between the electrodes, and electrolyte for submerging the electrodes. The negative electrode is made of active materials including at least one lowly graphitized carbon material and least one highly graphitized carbon material. The positive electrode made of active materials including lithium ion, transition metal ion and polyanion. The polyanion is selected from the group consisting of phosphate, silicate, sulfate and hydrofluoric acid. The transition metal ion is selected from the group consisting of the divalent ions of iron and manganese.
