Embodiment 2

[0007] In preferred embodiment 2 of the present invention, the coating or coating on the outer surface of the bipolar plates (1A, 1B) can be granular crystal lead dioxide.

[0008] In preferred embodiment 3 of the present invention, the light metal may be aluminum or aluminum alloy, titanium Ti or titanium alloy, or other similar light metal materials.

[0009] The preferred embodiment 4 of the present invention is that the composite material can be glass fiber, carbon fiber or other similar composite materials.

[0010] In preferred embodiment 5 of the present invention, the separator 3 may be made of liquid-rich liquid-absorbent composite glass fiber, or carbon fiber or other non-metallic materials.

[0011] In preferred embodiment 6 of the present invention, the base frame of the two polar plates (1A, 1B) can be formed with an arc-shaped bend at one end, or both ends with arc-shaped bends.

Embodiment 7

[0012] Preferred embodiment 7 of the present invention can be the storage battery completed by the above-mentioned 1-6 embodiment, and the polar plates (1A, 1B) that are arranged and combined by separators 3 in the electrolyte of the battery tank 4 are placed horizontally Yes, the bipolar plates can also be placed vertically to form a bipolar battery structure in which the plates are placed horizontally or vertically. But there is at least one pair of unipolar plates.

Embodiment 8

[0013] Preferred embodiment 8 of the present invention, can be according to the form of above-mentioned embodiment 1--7, adds polyfluoroalkane sulfonic acid or ethylene imine, lead sulfate, carbon powder in battery dilute sulfuric acid solution electrolyte.

[0014] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0015] 1. The battery plate adopts double-layer or multi-layer coating, among which the newly added pb and cd coatings are used as transition layers, which do not directly participate in the chemical reaction of the battery.

[0016] 2. Only one type of active material is used to make the plate, and the cost of the coating is lower than that of traditional batteries using two active materials with different formulations, which simplifies production and technical management.

[0017] 3. Use pbo from dark to black crystals 2 The active material used as the plate is more effective than the traditional brown fine ...

Abstract

This invention discloses a quickly charged long life accumulator including a battery tank made of insulation materials and positive, negative pole plates of multiraw baffles arranged in gaps in the electrolyte and a collelcting bar collecting the pole plates and binding post extending out of the battery cover, the key is to take light metal or compount material as the two pole plates to matrix frame, two sidesurfaces are plated with two layers of coating of active substances, the electrolyte is compound electrolyte with additives enabling huge increases of micro pore rate on the pole plates and quickly penetrates and enters inside to contact with reacted active substances. It can be quickly charged by large current.

Description

1. Technical field [0001] The invention relates to a lead-acid storage battery used in equipment such as automobiles, motorcycles and ships. In particular, it can be used for a long-life accumulator capable of fast charging on an electric bicycle energy device. [0002] The invention is an improvement to the existing lead-acid storage battery. 2. Background technology [0003] Lead-acid batteries in the known technology are mainly made of lead dioxide PBO soaked in the electrolyte of the battery box 2 The positive and negative plates coated with the active material and the separators between them, as well as the busbars and terminals for the output current are composed. There is only one layer of coating composed of two different substances on the pole plate, and the electrolyte is a dilute sulfuric acid solution without additives. Its pole plate is a unipolar pole plate, one pole plate has one polarity (positive pole or negative pole), and the voltage of a single battery...
