Abstract
The active matter composite features that Ax, By, Cz, and Du are added in traditional lead powder and sulfuric acid solution, where A is alpha or beta naphthalene acid, B is barium sulfate, C is hunmic acid or tannin extract and D is diffusant. If the composite is used as activating matter of megative electrode in lead-acid accumulator, the ordinary or enclosed accumulator can provide efficient discharge power with better start function at -40 deg.C. Its technical specifications can reach or exceed the requirement of SBA 2101-88 and SB3108-82 standards.
Description
The present invention relates to the lead acid accumulator field, especially a kind of acid accumulator negative pole lead composition of active material.
Common rapid in the world today with the development of totally-enclosed battery technology, be widely used in various environment such as indoor, outdoor.But general storage battery only adapts to temperature more than-18 ℃, this is because the swelling agent that adds in the negative electrode active material lead plaster at present mainly is humic acid, lignin, lignin, sulfonate, synthetic tanning material, roasting glue, barium sulfate etc., when being lower than-18 ℃, negative electrode active material surface area shrinkage and passivation phenomenon can occur in circulation.Therefore influenced the charge-discharge performance of battery.Can not satisfy the instructions for use of severe cold area.
Purpose of the present invention is intended to prepare the composition of lead-acid battery negative pole active substance, to overcome weak point of the prior art by materials such as interpolation dye additives.
Purpose of the present invention can realize by following proposal.
Active mass composition for negative electrode of lead-acid accumulator comprises traditional lead powder and sulfuric acid solution.In the present invention, also added Ax, By, Cz, Du material.Wherein: A is alpha-or beta-naphthoic acid 0＜X≤0.8%; B is a barium sulfate, 0＜Y＜1%; C is humic acid or roasting glue, and 0＜z＜1%D is a diffusion agent N, 0＜u≤0.5%.
It all is the material with highly developed surface that the present invention utilizes dye additive one diffusion agent N, barium sulfate, humic acid or roasting glue, all has very high surface energy.They can reduce surface tension effectively when being adsorbed on electrode surface, thereby reduce the energy of system.And diffusion agent N is adsorbed in after the electrode, can also influence lead sulfate nucleation process dynamics, changes the crystalline texture of lead sulfate when discharging, and reaches the purpose of depassivation.
The present invention adds Ax outside lead powder and sulfuric acid solution, By, Cz, the Du material, its preferably adding proportion be: 0.3% alpha-or beta-naphthoic acid; 0.2% barium sulfate; 0.3% humic acid; 0.2% diffusion agent N.Or 0.3% alpha-or beta-naphthoic acid, 0.2% barium sulfate, 0.3% roasting glue, 0.2% diffusion agent N.
Below in conjunction with embodiment the present invention is described in detail.
