Abstract

The invention provides a hydrothermal preparation method of V10O24.12H2O. According to the method of the invention, an acidic solution is prepared from an organic acid and deionized water; then after a vanadium compound is added to the acidic solution, the vanadium compound is reacted with ingredients in the acidic solution under a hydrothermal condition; next after the reacted solution is cooled down, the product obtained by the reaction is soaked in deionized water then is filtered and dried, thus the obtained V10O24.12H2O has dark green color, has silvery luster after sheeting, has a micron-sized ribbon-shaped morphology under a scanning electron microscope, and has relatively high crystallinity as shown in X-ray diffraction. The method has low cost and simple synthesis process path, allows the reaction conditions to be easy to control, allows the final product to have high purity and high crystallinity, enables the particle size and the particle size distribution to be adjusted and controlled, and is convenient for industrialized mass production.

Description

technical field [0001] The present invention relates to a V 10 o 24 12H 2 Hydrothermal preparation of O. Background technique [0002] Lithium-ion batteries have attracted much attention due to their high specific capacity, high voltage, long charge and discharge life, and low environmental pollution. The development of lithium-ion battery materials has always been a research hotspot. With the deepening of lithium ion battery research from chemical redox mechanism to lithium ion intercalation and deintercalation mechanism, a large number of researchers have been attracted to study the oxides / salts of 3d transition metal elements, such as lithium cobaltate, lithium manganate, Cobalt-nickel-manganese ternary materials, lithium iron phosphate and other materials have been developed and applied to industrial production. However, the pace of researchers looking for new lithium-ion battery materials has not stopped. As a typical multivalent transition metal element, vanadium ...
