Abstract

The invention belongs to the technical field of hydrogen storage, and particularly relates to a manufacturing method of a high-pressure hydrogen storage bottle. The manufacturing method of the high-pressure hydrogen storage bottle comprises the following steps that a cylindrical carbon nanotube fiber braided fabric is obtained, the cylindrical carbon nanotube fiber braided fabric is of an integralstructure, and the cylindrical carbon nanotube fiber braided fabric is not provided with a joint in the longitudinal direction; and an inner container is obtained, after the cylindrical carbon nanotube fiber braided fabric sleeves the outer surface of the inner container, curing treatment is carried out to obtain the high-pressure hydrogen storage bottle with carbon nanotube fibers wrapped on theouter surface. According to the manufacturing method of the high-pressure hydrogen storage bottle, after the cylindrical carbon nanotube fiber braided fabric not provided with the joint in the longitudinal direction and of the integral structure sleeves the outer surface of the inner container, curing treatment is carried out to obtain the high-pressure hydrogen storage bottle with the carbon nanotube fibers wrapped on the outer surface, the cylindrical carbon nanotube fiber braided fabric and the inner container are closely combined, the circumferential compression strength of a container can be effectively improved, the high-pressure hydrogen storage bottle is suitable for storing hydrogen, good in storage stability and high in compression strength, and simple preparation process and easy operation are achieved.

Description

technical field [0001] The invention belongs to the technical field of high-pressure containers, and in particular relates to a high-pressure hydrogen storage bottle and a manufacturing method thereof. Background technique [0002] With the development of hydrogen energy vehicles, not only light, compact, safe and economical storage methods are required for hydrogen storage, but also the battery life requirements of vehicles must be met, which must reach at least 500 kilometers. requirements. Although various hydrogen storage technologies are currently available, none of them fully meet all the requirements of the automotive industry. In fact, finding a solution to the hydrogen storage problem is considered by many to be the overarching challenge of the hydrogen economy. [0003] At present, the storage of hydrogen mainly includes: as a compressed gas in a container; as a liquid in a Dewar or storage tank (stored at -253°C); by absorption or reaction with a metal or compou...
