电动汽车的广泛使用可能对城市空气质量、国家能源独立和国际贸易平衡产生重大影响。高效电池是开发实用电动汽车的关键技术要素。介绍了以固体氢化物相贮氢的高能量密度、高功率、长寿命、耐滥用、宽工作温度范围、快速充电能力和全密封免维护运行的金属氢化物镍电池的科学技术。在几个长度尺度上使用结构和组成无序的广泛的多元素金属氢化物材料已经被设计用作该电池中的负极。电池在环境温度下工作，由无毒材料制成，并且可回收。已实现了制造技术的示范。
Widespread use of electric vehicles can have significant impact on urban air quality, national energy independence, and international balance of trade. An efficient battery is the key technological element to the development of practical electric vehicles. The science and technology of a nickel metal hydride battery, which stores hydrogen in the solid hydride phase and has high energy density, high power, long life, tolerance to abuse, a wide range of operating temperature, quick-charge capability, and totally sealed maintenance-free operation, is described. A broad range of multi-element metal hydride materials that use structural and compositional disorder on several scales of length has been engineered for use as the negative electrode in this battery. The battery operates at ambient temperature, is made of nontoxic materials, and is recyclable. Demonstration of the manufacturing technology has been achieved.
