Abstract

AMBROSIO, Renato Canha  and  TICIANELLI, Edson Antonio. Nickel-metal hydride batteries, an alternative for the nickel-cadmium batteries. Quím. Nova [online]. 2001, vol.24, n.2, pp.243-246. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422001000200015.

Nickel metal hydride (Ni-MH) batteries have emerged as an alternative for replacement of nickel-cadmium batteries, because of their more environmental compatibility and high energy capacity. In this article, we described the properties and applications for Ni-MH batteries, giving some emphasis on the metal-hydride electrode, including the description of composition, the charge storage capacity and the discharge profile. The key component of the nickel-metal hydride electrode is a hydrogen storage alloy whose composition is formulated to obtain a high stable material over a large number of charge-discharge cycles.

Keywords : metal-hydride batteries; hydrogen storage alloys; environmental protection.
