| Nickel metal-hydride (NiMH)
technology has been used
commercially since the early
1990's, mainly in consumer
applications such as toys and
portable electronics. During
the earlier part of this period,
nickel cadmium (NiCd) was
the mainstream technology to
which NiMH was often
compared. Even in these
early
days, it was recognised that
NiMH batteries were not only
able to achieve higher energy
density than NiCds, but were
more environmentally
friendly. |
