1. Working principle of nickel-cadmium battery

Nickel-cadmium batteries are rechargeable batteries that convert chemical energy into electricity through REDOX reactions. It consists of a negative electrode (the negative material is Cd), a positive electrode (the positive material is NiOOH), and an electrolyte (the main component is KOH).

2. Features of nickel-cadmium batteries

Long cycle life;
Wide use temperature range;
Strong resistance to electrical misoperation;
The discharge voltage is stable;
High mechanical strength;
Easy to use and maintain

3. The main characteristics of nickel-cadmium batteries
Discharge system: various conditions specified when the battery is discharged, including discharge time, discharge current, ambient temperature, termination voltage, etc.
Discharge method: including constant discharge, constant resistance discharge, continuous discharge and intermittent discharge. Common termination voltage: When the battery is discharged, the voltage drops to the working voltage that is no longer suitable for continuous discharge.
Discharge current: the size of the current when discharging, generally expressed by the discharge rate. Discharge rate refers to the rate at which the battery discharges, often expressed as "hourly rate" and "multiplier". "Hour rate" is the discharge rate expressed by the discharge time, that is, the number of hours required to discharge the rated capacity with a certain current, for example: 1 hour rate discharge current =C/1, 2 hour rate discharge current =C/2, and so on; "Rate" is the discharge current to indicate the discharge rate, for example: 1 rate discharge current =1C, 2 rate discharge current =2C, and so on.
Theoretical capacity: The amount of electricity given by assuming that all active substances participate in the flow reaction is based on the amount of active substances and the use of Rady's law.
Actual capacity: The amount of electricity actually released by the battery under certain discharge conditions.
Rated capacity: When designing and manufacturing a battery, the minimum amount of electricity that should be released by the battery under certain discharge conditions is specified or guaranteed. For example, for the battery model EBL100, 100 is the rated capacity value, that is, 100Ah.
