New materials for military industry in China (twelve) -- present situation and development of hydrogen storage materials

Date:2017-08-08

Some transition metal clusters, alloys and intermetallic compounds, due to its special crystal structure, hydrogen atom can easily penetrate the tetrahedral metal lattice or eight surface gap position, forming a metal hydride, this material is known as hydrogen storage materials.
In the weapon industry, the lead-acid batteries used by tanks and vehicles need to be recharged frequently because of their low capacity and high self discharge rate, so it is very inconvenient to maintain and transport. Influence of discharge power to battery life, charging state and temperature, under the condition of cold weather, the tank vehicle starting speed will be significantly decreased, even unable to start, this will affect the combat capability of tank. Hydrogen storage battery has the advantages of high energy density, over charging, shock resistance, low temperature performance, long service life and so on. It has a broad application prospect in the future development of MBT batteries.
