NiCd Nickel Cadmium Battery Technology Overview
The Nickel Cadmium, NiCd or Ni-Cd Battery was the first type of
rechargeable cell that could be used for portable electronics
equipment. Although the Lead Acid battery had been available for
many years, it was mainly used for automotive batteries. Th NiCd
might easily be used as a direct replacement for many conventional
primary batteries and its usage quickly caught on. Currently few
NiCd batteries can be bought, but did fill a gap in the market that
no other battery of the time could meet. Occasionally old Nickel
Cadmium Battery can still be found in stocks or possibly even in
use.
NiCd or Ni-Cd Cells are able to provide an almost direct
replacements for zinc carbon or alkaline primary batteries. They
generally are able to retain less charge than these cells, but have
the obvious advantage that they are able to be re-charged. This
means that although the initial purchase cost is higher than the
equivalent primary cells, costs can be saved after a few charge /
discharge cycles.
Ni-Cd Battery Pack Manufacturer tell you the NiCd cells have an
extremely low leverl of inner resistance. A good excellent alkaline
cell may have an inner resistance of about 300 milli-ohms when new.
This figure might rise to about 900 milli-ohms when 20% discharged
and several ohms when almost completely discharged. A NiCd has very
much lower figures, and any innernal resistance can be ignored for
most purposes as it's of the order of only a few milli-ohms,
dependent upon the exact type of cell and the maker. This does mean
that the cell is capable of producing very high currents,
especially if the cell is inadvertently short-circuited. In light
of this care has to be taken to make sure this doesn't occur as
large quantities of heat could be produced.
Ni-Cd Battery Cell Performance:
1. Ni-Cd Cell Charge Curve At 0.1C For 16h At 55 Degree
2. Ni-Cd Cell Discharge Curve At 0.25C At 55 Degree
3. Ni-Cd Cell Charge Efficiency At Different Temperature
4. Ni-Cd Cell Capacity Change At Permanent Charge At 55 Degree
(0.05C Floating)
5. Ni-Cd Cell Cycle Life Curve
