Rare Earth Hydrogen Storage Alloy Powder
	The development of hydrogen-storage alloys used in high-power nickel/metal hydride batteries has become an important application of Rare Earth metals, especially Lanthanum Metal. Various methods of improving the high-rate dischargeability of the metal-hydride negative electrode are invented. Our recent developed powders provide optimization of Rare Earth and Nickel composition, also called Lanthanum-Nickel Battery Alloy, combined with appropriate amounts of additive, significantly improves the high-rate capability of hydrogen-storage alloys, which may be suitable for use in high-power NiMH batteries.
