Apart from the voltage, its specific energy is around 50-60 Wh per Kg.
#NICAD C BATTERY SERIES#
Number of cells are connected in series or parallel to get the required voltage. In general, each voltage for a Nickel-cadmium battery would be approximately 1.2 V. Similarly, nickel is also poisonous to the human respiratory system. It has a direct effect on the digestive system. The average presence of cadmium in the human body is approximately 1 microgram per liter. Cadmium even has a physiological effect on the system. Cadmium is a heavy metal posing several risks to the human body. Nickel-cadmium battery is very toxic to the human body. Beyond this temperature range, the battery fails to operate and even chances of explosion exist. The temperature range for nickel battery is 0 to 45-degree centigrade during charging and -20 to 65 degrees centigrade during discharging. It results in nickel oxide and cadmium oxide. The reminder equation is given by the third equation, where nickel is combined with cadmium and water. It may be noted that the electrons in both the equations get canceled. This results in cadmium oxide and electrons. On the anode side, the cadmium layer is also combined with OH ions which are obtained from the separators layer. Later H2O is obtained as one of the byproducts. For the provision of H20, the separator layer is soaked with water for the initial reaction. The need for the separator layer as mentioned before is the provide the OH ions required for the chemical reaction. It gives an output of Nickel oxide OH ions. The first equation represents the reaction between the cathode layer nickel and the separator.
The chemical equations representing the chemical reaction can be given as Similarly, when not in use, it is recommended to remove the battery out of the device. The case of the battery is never opened, as all the layers are exposed and it may cause harm to the person using. It must be noted that, due to chemical reactions taking place within the batter, it always hazardous to work with the battery. The outer case is to provide protection to the inner layers from external factors such as damages and mishandling of the battery. The separator layer is connected to this ring. The insulator gasket is the place where the insulation ring is kept nearby. The purpose of the insulator ring is to provide insulation between the two layers. Apart from these, it also consists of a safety valve, sealing plate, insulation ring, insulation gasket, and an outer case. The separator layer between the two layers is made up of KOH or NaOH. Nickel-Cadmium Battery DiagramĪs shown, in the diagram, the nickel acts as a positive electrode collector and the cadmium layer acts as a negative layer collector. The nickel-cadmium battery diagram is shown below. The cadmium layer acts as the anode for the nickel-cadmium battery. Above the separator layer, cadmium is placed.
Its purpose is to provide required OH negative ions, for the chemical reaction. It must be noted that this separator layer must be soaked in water or moist. Above the nickel oxide layer, a layer of KaOH is kept, which acts as a separator. This layer of nickel oxide acts as a cathode layer.
