Electrochemical performance of raw natural graphite flakes as an anode material for lithium-ion batteries at the elevated temperature

Raw natural graphite flake was studied as an anode material for lithium-ion batteries at both the elevated and the room temperature. Lithium capacity is increased at the elevated temperature as compared to that at the room temperature. The effect of temperature was investigated by electrochemical methods in combination with ex situ X-ray diffraction (XRD).
