The invention relates to a method for preparing a carbon-coated lithium zinc titanate nanoribbon. TiO2 particles are put in a NaOH solution for performing a hydrothermal reaction to obtain a precursor; and then the carbon-coated lithium zinc titanate nanoribbon is prepared, under the condition of the existence of glucose, by a high-temperature calcining method. The preparation method for the carbon-coated lithium zinc titanate nanoribbon is simple, low in cost, low in energy consumption and high in repeatability.
