What is the service life of Ni-Cd Battery?

As a Ni-Cd Battery Pack Supplier, share with you. Rechargeable battery is a rechargeable battery with a limited number of recharges. It is used with a charger. The market usually sells No. 5 and No. 7, but there are also No. 1. The advantages of rechargeable batteries are economical, environmental protection, sufficient power, suitable for high-power, long-term electrical appliances (such as walkmans, electric toys, etc.). The voltage of the rechargeable battery is lower than that of the same type of disposable battery. The AA battery (charge 5) is 1.2 volts, and the 9V rechargeable battery is actually 8.4 volts. Now generally the number of charge can be around 1000 times. As of February 2012, there are only five types: Ni-Cd Battery, nickel-metal hydride, lithium ion, lead storage, lithium iron.

The active material on the positive plate of a lead-acid battery is lead dioxide, the active material on the negative plate is sponge-like pure lead, the electrolyte is a sulfuric acid solution of a certain concentration, and the electromotive force between the plates is about 2V.

Ni-Cd Battery

The active material on the positive plate of the nickel-cadmium battery is nickel oxide powder, and the active material on the negative plate is cadmium oxide powder. The active materials are respectively wrapped in perforated steel strips, which become the positive and negative plates of the battery after pressure forming. The electrolyte is usually a potassium hydroxide solution. The open circuit voltage of the battery is 1.2V.

The material of the positive plate of the nickel metal hydrogen battery is nickel oxide powder, the material of the negative plate is a hydrogen absorbing alloy, and an electrolytic potassium hydroxide solution. The open-circuit voltage of the battery is 1.2V. LiCoO2 composite metal oxides are used for lithium ion batteries to form anodes on aluminum plates, and lithium carbon compounds are used to form cathodes on copper plates, with submicron-sized microporous polyolefin film separators between the plates, electrolytic The liquid is an organic solvent. The open circuit voltage is 3.6V.

Lithium polymer battery is an improved type of lithium-ion battery. There is no battery fluid. Use polymer electrolyte instead, which is more stable than ion battery. Open circuit voltage is 3.6V.

The battery capacity represents how much power the battery can store. The numbers we see on the battery packaging generally refer to the battery capacity identification. Expressed in unit ampere hours or milliamp hours. It is a composite unit composed of the product of the current unit and the time unit, which represents the ability of the battery to continuously discharge at a constant current. A fully charged battery can be discharged with 200mA for 10 hours. By multiplying the current and time, we can get the capacity of this battery is 2000mA.H. If it is discharged with 400mA, the available time is 5 hours.

Energy density: The electrical energy capacity contained in a unit volume or unit weight. For the same power requirements, a battery with a high energy density can be smaller in size and lighter in weight.
