CREM is one of the oldest institutes in studying rare earth hydrogen storage materials. CREM has accomplished many key national projects and won some important scientific awards. Now, a production line, which can produce 300 tons of rare earth hydrogen storage alloys per year, has been established. The electronic capacity of rare earth hydrogen storage alloy powders reaches 330~340mAh per gram. The rare earth hydrogen storage alloy powders can reach to the requirements of Ni/MH battery.
