Product performance:
1. High life. The Ni Cd battery can provide more than 500 charge
and discharge cycles, and its service life is almost equal to the
service life of the equipment using the battery.
2. Excellent discharge performance. In the case of high current
discharge, nickel cadmium battery has low internal resistance and
high voltage discharge characteristics, so it is widely used.
3. Long storage period. The Ni Cd battery has a long storage life
and few restrictions, so it can be charged normally after long-term
storage.
4. High rate charging performance. The nickel cadmium battery can
be quickly charged according to the application needs, and the full
charge time is only 1.2 hours.
NiCd Nickel Cadmium Battery Technology Overview
Nickel Cadmium (NiCd) batteries are a type of rechargeable battery
that use nickel oxide hydroxide and metallic cadmium as the active
materials for the positive and negative electrodes, respectively.
NiCd batteries have been widely used for several decades and have a
long history in various applications. Here is an overview of NiCd
battery technology:
1.Chemistry: NiCd batteries use an alkaline electrolyte, typically
potassium hydroxide (KOH), to facilitate the electrochemical
reactions between the active materials. The positive electrode
(cathode) consists of nickel oxide hydroxide (NiOOH), while the
negative electrode (anode) comprises metallic cadmium (Cd).
2.Performance: NiCd batteries are known for their robustness and
durability. They can deliver high currents and perform well in
extreme temperature conditions. NiCd batteries have a relatively
flat discharge voltage curve, providing consistent power output
throughout their discharge cycle.
3.Memory Effect: NiCd batteries are susceptible to the memory
effect, also known as voltage depression. This effect occurs when
the battery is repeatedly recharged without being fully discharged,
causing it to remember the lower capacity and voltage level. To
mitigate this effect, periodic deep discharging and recharging
cycles are recommended.
4.Self-Discharge: NiCd batteries have a relatively high
self-discharge rate compared to other rechargeable battery types.
They can lose a significant portion of their charge over time, even
when not in use. Therefore, regular maintenance and recharging are
necessary to ensure optimal performance.
5.Environmental Impact: One significant concern with NiCd batteries
is the presence of cadmium, a toxic heavy metal. Improper disposal
or recycling of NiCd batteries can lead to environmental
contamination. Proper recycling methods are required to handle and
dispose of NiCd batteries safely.
6.Memory-Free Variant: "Low self-discharge" or "memory-free" NiCd
batteries are available in the market. These batteries are designed
with improved chemistry and reduced memory effect. They have a
lower self-discharge rate, allowing them to retain their charge for
longer periods when not in use.
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
