Problems solved by technology

The existing colloidal electrolyte has not yet reached a satisfactory level of crack quality, and there is room for improvement
At the same time, the current colloidal internal formation process is to pour acid into it first, then pour the acid out and then pour it into the colloidal electrolyte. The battery produced by this process is easy to separate because the electrolyte sulfuric acid and the colloidal electrolyte added later have not been fully sheared and stirred. Cause the colloidal hydration to leak acid in the later use of the battery

Embodiment Construction

[0023] Embodiments of the present invention will be described below.

[0024] The colloid formation process of the lead-acid storage battery of the present invention is as follows: first, the raw plate battery is directly perfused with colloid without adding acid; Cutting force keeps the electrolyte in a stirring state during the formation process, so that the colloidal electrolyte is always in a liquefied state and will not gel.

[0025] The charger has the characteristic of frequency conversion calculus charging, and maintains a reasonable charging current battery (0.1-0.3 times of the rated capacity is the range of charging current value variation), so as to improve the receiving efficiency of the battery charging capacity, using the calculus charging principle of the charger, Assist the electrolyte to maintain a more reasonable formation temperature, so that there is no need for circulating water to cool down.

[0026] As a result, the colloidal electrolyte has good thixo...

Abstract

The invention provides an internal formation technology for colloid electrolyte of a lead-acid battery. According to the core technique, on the basis of a turbulence calculus charging principle and the high thixotropic property of the colloid electrolyte, the colloid electrolyte is always in a liquid state in the whole formation process of the battery, the formation charging efficiency is improved due to interinfiltration of electrolyte and active substances, and the colloid electrolyte is solidified naturally. The colloid electrolyte gels so as to form a plurality of tiny cracks, thereby improving oxygen cycle, reducing moisture loss to prevent the gel from hydrating in using, and improving the property of the lead-acid battery. The charge acceptance of the battery is improved, and the total charge accepted by the battery is improved to 95% from 75%.

Description

technical field [0001] The invention relates to the internal formation technology of colloidal lead-acid batteries. Background technique [0002] In colloidal lead-acid batteries, since the positive and negative electrodes are surrounded by colloidal electrolyte, the oxygen generated on the positive electrode will diffuse to the negative electrode through the cracks in the colloidal electrolyte to complete the oxygen cycle. Therefore, the quality of the cracks in the colloidal electrolyte is directly affect the quality of the battery. The existing colloidal electrolyte has not yet reached a satisfactory level of crack quality, and there is room for improvement. At the same time, the current colloidal internal formation process is to pour acid into it first, then pour the acid out and then pour it into the colloidal electrolyte. The battery produced by this process is easy to separate because the electrolyte sulfuric acid and the colloidal electrolyte added later have not be...
