AN ANODE MATERIAL FOR ULTRAF AST-CHARGING LITHIUM ION BATTERIES AND A METHOD OF ITS SYNTHESIS

摘要

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.
