Construction Features

Structure

The plate groups of Changhong KPX series Ni-Cd battery mainly consist of nickel positive plates , cadmium negative plates, separators and terminal pillar ,which firmly rigged in engineering plastic container ,then the cell container and cell lid are pasted (or heat-welded) together ,which are sealed by rubber O rings type washer at the terminal pillar.

The battery terminal are respectively marked by red and blue (or black) plastic polarity marks as positive and negative polarity with symbol as permanent mark on the positive terminal. The plastic vent plugs are assembled on the cell lid. (see Figure 1).

The flip top vent plug is fitted on the battery during the operating ,which can not only prevent particles getting into the cell , but also exhaust the gas generated  inside while charging  ,so as to ensure the battery working safely and reliably.

Working Principle

Nickel-cadmium battery is an equipment which can convert electric energy into chemical energy by charging , and convert chemical energy into electric energy by discharging. While charging and discharging, redox reaction takes place on the positive and the negative electrodes , the electro-chemistry reaction formula follows:

The formula is:

2H₂O → O₂  ↑ 2H₂ ↑

Consequently, there will be a certain amount of water consumption during operation, it is recommended to periodically check and adjust the electrolyte level according to the manufacturer s instruction

Based on the above reactions, we can see, when the battery is being charged or discharged, in theory, there is no electrolyte consumption, but the positive and negative plates have high porosity with the properties of sucking and draining electrolyte. The electrolyte level rise during charging , because of draining electrolyte. While being discharged, electrolyte level downs because of sucking electrolyte. In addition ,the separator has high sucking capability, therefore, the electrolyte level changes a lot during the process of charging and discharging. At the end of

charging (or over-discharging), some water is electrolyzed to produce oxygen and hydrogen.
