An anode material for ultrafast-charging lithium ion batteries, the anode material comprising C—Li4Ti5O12. A method of synthesizing an anode material for ultrafast-charging lithium ion batteries, the method comprising the steps of: adding lithium to an organic alcohol to form a first solution; adding titanium via an organic titanium source to the first solution to form a second solution; adding water to the second solution to form a diluted second solution; heating the diluted second solution at a temperature ranging from about 80° C. to about 180° C. to obtain solid Li4Ti5O12; and annealing the solid Li4Ti5O12 in the absence of air to obtain the anode material comprising C—Li4Ti5O12.
