Embodiment Construction

[0029] Examples of the present invention are exemplified in the form of a list below. The lead paste of the present invention is composed of the following weight percentage components based on its weight:

[0030] Example Short fiber% Water% Lead powder%

[0031] 1 0.1 10 margin

[0032] 2 0.1 5 margin

[0033] 3 0.2 5 margin

[0034] 4 0.4 10 margin

[0035] 5 0.1 15 margin

[0036] The short fiber is polyacrylonitrile material.

[0037] The preparation process of lead paste:

[0038] 1. Add short fibers to the water and stir to evenly disperse the short fibers;

[0039] 2. Add lead powder and stir to make it even.

[0040] The role of each component:

[0041] 1. Lead powder is used as the positive active material to give the battery capacity;

[0042] 2. Short fibers are used as the skeleton for the bonding of active materials.

Abstract

This invention relates to a value controlled lead acid battery positive lead paste prolonging the working life of batteries and devices since it can avoid corrosion to the devices, harm to human bodies or non-uniform mixing which is composed of the components in following weigh percentage taking its weight as the primary standard: short fiber: 0.08-0.5%, water: 5-20% and lead powder for rest.

Description

Technical field [0001] The invention relates to a lead-acid battery electrode plate, particularly a lead paste layer on a positive electrode plate. Background technique [0002] Valve-regulated lead-acid batteries have been widely used in fields such as backup power supply, energy storage and power supply. However, the current fatal problem of lead-acid batteries is mainly the short cycle life of the batteries. The positive active material is the key to restricting this problem. The earliest positive active material used two lead plates as electrodes for repeated charging and discharging. The lead plates were transformed during the charging and discharging process. It can be said that the positive active material at that time was pure lead. Later, industry insiders used active materials to cover the grid to make battery plates, such as Faure using Pb 3 O 4 As the active material, lead paste is coated on the lead sheet to make the electrode plate.
