A pure lead gel battery

Abstract

The invention relates to the field of lead-acid batteries, which is a pure lead colloidal battery, mainly comprising a shell, a positive grid, a positive plate, a negative grid, a negative plate, a silicon phosphogel colloidal electrolyte, and a separator between the positive plate and the negative plate. Plate, positive grid, and negative grid are all made of pure lead-lead plate; the separator is made of PVC and nano-silica polymer microporous material, the diameter of the micropore is 1-10 μm, and there is a glass on the surface opposite to the positive grid. The fiber adsorption layer has a thickness of 1.5-2.0 mm. The beneficial effects are: adopting the pure lead thin plate design, it has the characteristics of wide operating temperature range of the battery, long cycle life under partial charge, superior charging and receiving capacity of large current, environmental protection, small internal resistance, and good charging receiving capacity. It is used in fields that require short-term high-power backup, fast and continuous large-scale charging and discharging.

Description

technical field [0001] The invention relates to a lead-acid storage battery, in particular to a pure lead colloid storage battery. Background technique [0002] At present, the commonly used battery is AGM lead-acid battery, the battery electrolyte is easy to overflow, corrode the terminals, pollute the environment, and the cycle life is short. In order to overcome the above defects, the patent ZL92104882.3 discloses a colloidal battery and its preparation method , although the colloidal electrolyte replaces the fluid sulfuric acid electrolyte and solves some problems such as leakage of the AGM battery, the large current discharge of the battery and the storage capacity are not ideal.

Problems solved by technology

[0002] At present, the commonly used battery is AGM lead-acid battery, the battery electrolyte is easy to overflow, corrode the terminals, pollute the environment, and the cycle life is short. In order to overcome the above defects, the patent ZL92104882.3 discloses a colloidal battery and its preparation method , although the colloidal electrolyte replaces the fluid sulfuric acid electrolyte and solves some problems such as leakage of the AGM battery, the large current discharge of the battery and the storage capacity are not ideal. There is also a patent ZL01259212.9, which solves the problem of charging acceptance, The problem of large current discharge capacity and capacity reserve capacity, the publication number is: CN1503393A solves the problem of fast self-discharge and short service life. Later in the development process, some patents on the new technology of colloidal batteries appeared, and colloidal battery technology was once again obtained. enhanced and improved

However, the gel battery still has the following two problems that have not been resolved: 1. The design material cost is 1.5 to 2 times that of the AGM battery, which is difficult to be accepted by communication operators and the civilian market; 2. The gel battery is designed with thick plates and PVC separators Due to low porosity and high internal resistance of fixed colloidal electrolyte, the medium and large rate discharge performance of the battery is poor, so it is not suitable for use in high-power UPS systems and starting markets such as vehicles and ships.

So far, there is no effective technology to solve the above two problems
