Lead battery industry definition
Commonly used rechargeable batteries In addition to lithium batteries, lead batteries are also a very important battery system. The advantage of the lead storage battery is that the electromotive force is relatively stable during discharge, and the disadvantage is that it is smaller than the energy (the electric energy stored per unit weight) and is highly corrosive to the environment. Lead storage batteries have a wide operating voltage, a wide range of operating temperatures and current ranges, hundreds of cycles of charge and discharge, good storage performance (especially suitable for dry charge storage), and low cost.
Lead-acidbattery: Its volume and weight have not been effectively improved, so it is most commonly used on cars and motorcycles. The improvement of lead-acid battery ** is the recent use of high-efficiency oxygen recombination technology to complete water regeneration, thereby achieving the purpose of completely sealing without adding water, and the "free water-free battery" can be used for up to 4 years ( Single plate voltage 2V).
Since its invention in 1859 by Plant, the lead-acid battery has a history of more than 150 years and is very mature. It is the most widely used chemical power source in the world. Although new batteries such as nickel-cadmium batteries, nickel-hydrogen batteries, and lithium-ion batteries have been introduced and applied in recent years, lead-acid batteries still have high discharge performance, stable voltage characteristics, wide temperature range, and large capacity of single cells. A series of advantages such as high safety and abundant raw materials, renewable and low price, occupy a strong position in most traditional fields and some emerging applications.
Lead battery classification
(1) Classification according to battery plate structure: formed, pasted and tubular batteries;
(2) According to the battery cover and structure classification: open type, exhaust type, acid-proof explosion-proof type and sealed valve-controlled storage battery;
(3) Classification according to battery maintenance methods: There are common type, less maintenance type, maintenance-free batteries.
(4) According to the relevant national standards, the main battery series products are:
Starter type battery: mainly used for starting and lighting of automobiles, tractors, diesel engines, etc.;
Fixed battery: mainly used for communication, power plant, computer system as a backup power source for protection and automatic control;
Traction type battery: mainly used for various battery vehicles, forklifts, forklifts and other power sources;
Railway battery: mainly used for railway diesel locomotives, electric locomotives, passenger car starting, lighting power;
Motorcycle battery: mainly used for motorcycle starting and lighting of various specifications;
Coal storage battery: mainly used for electric locomotive traction power supply;
Storage battery: mainly used for wind power and hydropower storage.
