1. A preparation method of a nanotube hierarchically structured lithium titanate, wherein the method comprises the steps of:
S1. dispersing a titanium source into an aqueous solution containing lithium hydroxide and hydrogen peroxide and stirring to obtain a mixed solution;
S2. subjecting the mixed solution obtained in step S1 to a reaction by heating to obtain a precursor having a nanowire structure;
S3. subjecting the precursor having a nanowire structure obtained in step S2 to separation and drying;
S4. subjecting the precursor having a nanowire structure after separation and drying to a low-temperature annealing treatment; and
S5. subjecting the precursor having a nanowire structure after the low-temperature annealing treatment to a liquid thermal reaction to obtain the nanotube hierarchically structured lithium titanate.
