Short Description:

Introduction about 1.2V NiCd battery nickel–cadmium battery cells

Nickel-cadmium battery is a DC-powered battery. The nickel-cadmium battery can be charged and discharged more than 500 times, which is economical and durable. Its internal resistance is small, not only is low internal resistance, it can be charged quickly, but also can provide large current to the load, and the voltage change is small during discharge, which is a very ideal DC power supply battery.

We can produce different capacities according to customers requirements.

NiMH Vs NiCD Vs Lithium-ion

NiMH batteries

Ni-MH battery is a combination of hydrogen ion and metal nickel, and its power reserve is 30% more than that of nickel-cadmium batteries. It is lighter than nickel-cadmium batteries and has a longer service life. It has no pollution to the environment and no memory effect. The disadvantage of nickel-metal hydride batteries is that the price of nickel-cadmium batteries is much more expensive, and the performance is worse than that of lithium batteries.

Lithium Ion Battery

A high-energy density battery made of lithium-ion batteries. Lithium-ion battery is also a kind of smart battery, which can be matched with special original smart charger to achieve the shortest charging time, the longest life cycle and the largest capacity. Lithium-ion batteries are currently the best batteries. Compared with nickel-cadmium batteries and nickel-hydrogen batteries of the same size, it has the largest power reserve, the lightest weight, the longest life, the shortest charging time, and no memory effect.

There are two main types of rechargeable batteries: lead-acid batteries and alkaline batteries. The currently used nickel-cadmium (NiCd), nickel-metal hydride (NiMH) and lithium-ion (Li-Ion) batteries are all alkaline batteries.
NiMH batteries have good low-temperature discharge characteristics. Even at an ambient temperature of -20°C, using a large current (at a discharge rate of 1C) to discharge, the discharged electricity can reach more than 85% of the nominal capacity. However, when NiMH batteries are at a high temperature (above +40°C), the storage capacity will drop by 5-10%. The capacity loss caused by self-discharge (the higher the temperature, the greater the self-discharge rate) is reversible, and the maximum capacity can be restored to a few charge-discharge cycles. The open circuit voltage of NiMH battery is 1.2V, which is the same as NiCd battery.

The charging process of NiCd/NiMH batteries is very similar, requiring constant current charging. The difference between the two is mainly in the fast charging termination detection method to prevent the battery from overcharging. The charger performs constant current charging on the battery, and at the same time detects the battery voltage and other parameters. When the battery voltage rises slowly and reaches a peak value, the fast charging of the NiMH battery is terminated, while for the NiCd battery, the fast charging is terminated when the battery voltage drops by -△V for the first time. In order to avoid damage to the battery, fast charging cannot be started when the battery temperature is too low. When the battery temperature Tmin is lower than 10°C, the trickle charging mode should be switched to. Once the battery temperature reaches the specified value, the charging must be stopped immediately.
