Nickel metal hydride (Ni-MH) batteries have demonstrated key technology advantages for applications in new-energy vehicles, while the main challenge derives from the insufficient cycle lives (about 500 cycles) of their negative electrode materials—hydrogen storage alloys. As a result, progress in their devel
The commonly used analytic methods for determining the failure mode are also presented here. The most common failure mode of a Ni/MH battery is an increase in the cell impedance due to electrolyte dry-out that occurs from venting and active electrode material degradation/disintegration.
The Ni–MH battery is a safe and mature technology that possesses relatively high energy density (>300 Wh L –1 at the material level) and long cycle life if depth of discharge (DoD) is controlled (20 000 cycles for a DoD of 50%).
The resulting battery technology would enable independent scalability of energy and power of the Ni–MH battery chemistry, e.g., adjusted for 8 h energy storage cycles, and facilitate enormously the recyclability by simple replacement of solid materials in the accessible external reservoirs.
In each category, a general description about the principle and direction of development is given. Both the metal hydride (MH) alloy and nickel hydroxide as active materials in negative and positive electrodes, respectively, are reviewed extensively. Both thermal and battery management systems (BMSs) are also discussed.
Two novel candidate alloys, La 0.6 Ce 0.3 Y 0.1 Ni 3.7 Co 0.75 Mn 0.3 Al 0.35 and La 0.55 Ce 0.3 Y 0.15 Ni 3.7 Co 0.75 Mn 0.3 Al 0.35, show ultra-long cycle lives of 1325 and 1407 cycles, respectively, which are almost triple that of the commercial alloy (MmNi 3.55 Co 0.75 Mn 0.4 Al 0.3) that is used in Ni-MH batteries.
These materials form the basis for Ovonic Nickel-Metal Hydride batteries which have emerged as the leading battery technology for electric vehicle applications. Ovonic Batteries have the highest volumetric energy density available extending the practical range of electric vehicles from under 100 miles to over 200 miles.

Nickel-metal hydride batteries are similar to the proven sealed nickel-cadmium battery technology except that a hydrogen-absorbing negative electrode is used instead of the cadmium-based electrode. This eliminates cadmium, a toxic material, while this substitution increases the battery''s electric capacity (measured in ampere-hours) for a given weight and volume.
