Rechargeable Batteries

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.) There are five common types of rechargeable batteries: nickel-cadmium, nickel-hydrogen, lithium-ion, lead storage, and iron-lithium.

Material

Rechargeable battery is a rechargeable battery with a limited number of recharges. It can be used with a charger.

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.

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.

Features

Nickel-cadmium: small capacity with memory effect

NiMH: small memory effect, large capacity

Lithium ion: no memory effect, thin body, large capacity, due to different electrode materials, there are two types of electromotive force: 3.6V and 3.7V. Lithium battery performance is the best of the existing types of batteries, small size, light weight, large capacity. Widely used in digital cameras, notebook computers, mobile phones and other electronic products.

Lead storage: The electromotive force is about 12V. Lead storage batteries can be repeatedly charged and used. The electrolyte is a sulfuric acid solution and has a small internal resistance.

Lithium iron: Electricity is more sufficient, safer, and lighter. The main development direction of electric vehicles in the future.

Generally, the same type of rechargeable battery has a larger capacity, a larger volume, and a larger weight.
