Twicell Nickel-Metal Hydride (Ni-MH)
Batteries
What
is a Twicell Nickel-Metal Hydride
Battery
It's a
secondary battery which lasts more than
twice as long as CADNICA batteries.
Twicell uses hydrogen absorbing alloys
in its negative electrode (anode) and
nickel oxide in its positive electrode (cathode).
Since its release, the first in the
world in October 1990, the "Twicell"
sealed Nickel-Metal Hydride battery has
developed a strong reputation for high
capacity, high performance and high
quality. In November 1996, Sanyo was the
first manufacturer in the world to
achieve 300 million cells accumulatively.
The HR-4/3AU (3,500mAh) is a new battery
(volumetric energy density: 300Wh/l),
first marketed in May 1996, that well
exceeds the volumetric energy density of
lithium-ion batteries. Sanyo released
another Twicell battery of even higher
capacity (volumetric energy density:
340Wh/l) in the end of 1997. In addition,
the new Twicell HR-4/3FAU(4,000mAh),
released in September 1996, was
specially designed for notebook
computers and has the same diameter
(18mm) as the lithium-ion UR18650
battery
