The Technology. During the past decade, nickel-metal-hydride batteries have proven themselves in laptop computers, cellular phones, video cameras and other products in use worldwide. But adapting NiMH technol-ogy for electirc vehicle application has been challenging for battery developers because of the need to provide electric vehicles with
The overall reaction during discharge is: NiO (OH) + MH → Ni (OH)2 + M. During this process, free electrons are bound so that this pole becomes the positive electrode. The redox voltage of the reduction is approximately 0.49 V. The total voltage of the redox reaction is thus E 0 = 0.49V – ( – 0.83V) = 1.32V. The specific energy of a NiMH
The charge algorithm for NiMH is similar to NiCd with the exception that NiMH is more complex. Negative Delta V to detect full charge is faint, especially when charging at less than 0.5C. A mismatched or hot pack reduces the symptoms further. NDV in a NiMH charger should respond to a voltage drop of 5mV per cell or less.

The nickel metal hydride (Ni-MH) battery is a green battery. Compared with the traditional Ni-Cd battery, the Ni-MH battery is more environmentally friendly with a higher energy density [59]. The main challenges for the Ni-MH battery come from the insufficient cycle life of the hydrogen storage alloy anode (approximately 500 cycles) [60].
Research on nickel-metal hydride batteries started for a different purpose in the 1970s. At that time hydrogen was being considered as an alternate source of energy and the nickel-metal hydride cell we know today was touted as a possible means to store hydrogen. In recent years, the nickel-metal hydride battery has become a part of the

Program Objectives and Benefits. The objective of this program is to further develop the bipolar NiMH battery design to be used in high-energy and high-power energy storage applications. Improve efficiencies by reducing transmission peaking losses and shifting peak demands. Reduce power and voltage sag to users.
Since the use of nickel-cadmium batteries is prohibited for standard applications [6], Ni-MH systems remain one of the most reliable power sources for working at low temperatures below 0 • C
Metal hydride storage has a relatively high energy density by volume, but a relatively low energy density by weight (kWh/kg). Typical values are 1% to 9% by weight ( Zhang et al., 2010 ). This results in metal hydride storage tanks that are about four times heavier (250–300 kg) than gasoline tanks.
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
