NICKEL METAL HYDRIDE BATTERIES
Overview
As electronic products have come to feature more
sophisticated functions, more compact sizes and
lighter weights, the sources of power that operate
these products have been required to deliver in-
creasingly higher levels of energy. To meet this
requirement, nickel-metal hydride batteries have
been developed and manufactured with nickel
hydroxide for the positive electrode and hydrogen-
absorbing alloys, capable of absorbing and releas-
ing hydrogen at high-density levels, for the negative
electrode. Because Ni-MH batteries have about
twice the energy density of Ni-Cd batteries and a
similar operating voltage as that of Ni-Cd batteries,
they have become a mainstay in rechargeable
batteries.

Construction
Nickel-metal hydride batteries consist of a positive
plate containing nickel hydroxide as its principal active
material, a negative plate mainly composed of hydro-
gen-absorbing alloys, a separator made of fine fibers,
an alkaline electrolyte, a metal case and a sealing
plate provided with a self-resealing safety vent. Their
basic structure is identical to that of Ni-Cd batteries.
With cylindrical nickel-metal hydride batteries, the
positive and negative plates are seperated by the
separator, wound into a coil, inserted into the case,
and sealed by the sealing plate through an electrically
insulated gasket.
