| 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 increasingly
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 releasing 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 are
expected to become a mainstay in the
next generation of rechargeable batteries. |
|
|
|
|
| In
order to widen the useful applications
of the Ni-MH cell and to use its advantages
to the fullest, special purpose types
have been developed. Detailed characteristics
of special purpose batteries are shown
eleswhere as individual data sheets. |

A. Green power
Ni-MH batteries are free of Cadmium
and mercury. They are an environmental
friendly chemical power source.
B. Similarity with Ni-Cd batteries
These batteries have similar discharge
characteristics to those of Ni-Cd batteries.
C. Double the energy density of conventional
batteries
Ni-MH batteries have approximately double
the capacity compared with ' standard
Ni-Cd batteries.
D. Cycle life equivalent to 500 charge
and discharge cycles
Like Ni-Cd batteries, nickel-metal hydride
batteries can be repeatedly charged
and discharged for about 500 cycles(IEC
61436 charge and discharge conditions).
E. Rapid charge in approx. 1.2 hours
Ni-MH batteries can be rapidly charged
in about an hour using a specially designed
charger.
F. Excellent discharge characteristics
Since the internal resistance of nickel-metal
hydride batteries is low, conditions
for high-rate discharge up to 4CmA is
possible, similar to Ni-Cd batteries.

There
are three types of Ni-MH batteries:
(1) General type (Standard type)
(2) Consumer type
(3) High rate discharge type (P type)
