Lead-acid batteries are used in marine equipment, cable television, military equipment, emergency lighting systems, backup power supplies, large UPS and computer backup power stations, electric wheelchairs, golf carts, electric forklifts, railway systems, power stations, power systems.

Maintenance-free lead-acid batteries consist of positive and negative plates, separators and electrolytes, battery cells and connecting strips (or lead parts), terminals and exhaust valves. First, the main components of the battery 1, the pole plate is the core component of the battery, equivalent to the "heart" of the battery, which is divided into a positive plate, a negative plate. 2. The function of the separator is to isolate the positive and negative plates to prevent short circuit, which may be called “third electrode”. As a carrier of the electrolytic solution, it can absorb a large amount of electrolyte and function as a good diffusion of ions (ion conduction). For sealed maintenance-free batteries, the separator can also act as a "channel" for the positive plate to generate oxygen to the negative plate, allowing the plate to smoothly establish an oxygen cycle and reduce water loss. The key to maintenance-free separator batteries is the use of ultra-fine glass fibers.

3. Most of the electrolyte consists of pure water and sulfuric acid, mixed with some additives. The main role of the electrolyte lies in two aspects: one is to participate in the electrochemical reaction, which is one of the active substances of the battery; the other is to conduct electricity, and the battery is transferred through the ion in the electrolyte to play a conductive role, so that the chemical reaction can be obtained. Going smoothly. 4. The safety valve is one of the key components of the maintenance-free lead-acid battery. It is located at the top of the battery. It functions in four aspects: (1) Safety function, that is, when the gas pressure generated inside the battery reaches the safety valve pressure during the use of the battery, Opening the valve releases the pressure to prevent the generation of large amounts of gas.

(2) Sealing function, when the internal pressure of the battery is lower than the closing pressure of the safety valve, the safety valve is closed to prevent the internal gas acid mist from leaking out, and also prevent the air from entering the battery and causing adverse effects. (3) Ensure the normal internal pressure of the maintenance-free lead-acid battery, promote oxygen compounding in the battery, and reduce water loss. (4) Explosion-proof effect, some safety valves are equipped with acid-proof and anti-explosive tablets. Such as Panasonic battery. In addition, there are many types of safety valve structures, mainly cap type, umbrella shape, sheet shape and the like. It is common to make a hat-shaped crucible from a rubber with good elasticity, which has a simple structure and a low failure rate of use, and is therefore widely used.
