The new rare earth magnesium nickel-based hydrogen storage alloy electrode production line developed by BGXT, a leading rare earth alloy material technology company in China, has begun to operate normally. It is understood that the production line has a capacity of 200 tons/year, and the 280 kg of electrode products currently produced have entered the market.
The rare earth magnesium-nickel-based hydrogen storage alloy electrode material has the advantages of high capacity and low self-discharge, and is considered to replace the traditional AB5 type rare earth-based hydrogen storage alloy. The nickel-metal hydride power battery prepared by this new electrode product has excellent low-temperature stability performance. A large number of experiments have proved that the nickel-metal hydride power battery product prepared by the new material can make the car performance very stable, even in the extreme cold of the north. use. Ni-MH power batteries are currently used in hybrid vehicles by Toyota and other world mainstream car companies. In supporting the development of the new energy automobile industry, China also regards nickel-metal hydride power batteries as a key support object.
"We used the alloy preparation technology with independent intellectual property rights of Yanshan University to optimize the alloy structure characteristics through the matching relationship between the phase structure of the rare earth magnesium nickel-based hydrogen storage alloy and the electrochemical hydrogen storage performance, and developed rare earth magnesium nickel-based storage with different advantages. Hydrogen alloy new products.” said Xiao Ming, head of technology research and development.
It is reported that this production line is the first new rare earth hydrogen storage alloy production line with independent intellectual property rights in China. The battery capacity of this product as an electrode is more than 30% higher than that of traditional nickel-hydrogen batteries and hydrogen storage alloys. It is a key material for the production of high-capacity, wide-temperature range, high-tech, and low-power nickel-hydrogen power batteries.
Compared with nickel-cadmium batteries, nickel-metal hydride batteries made of new rare earth magnesium-nickel-based hydrogen storage alloy electrodes are more environmentally friendly and safer than lithium batteries. They can be widely used in hybrid batteries for automobiles, as well as solid-state hydrogen storage and hydrogen fuel cells among.
