Embodiment Construction

[0012] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0013] The invention is divided into two parts: the production of the full colloidal electrolyte and the production of the positive and negative plates of the battery.

[0014] Colloid of the present invention is all different from its formulation process of domestic popular colloid, and the process of making glue of the present invention is as follows:

[0015] 1. Use a 300-rpm low-speed disperser to form the colloid at one time, which is different from the traditional high-speed mixer for two-time forming;

[0016] 2. Add 1 ton of dilute sulfuric acid with a density of 1.34 g / cm3 into the disperser, then add 40 kg of fumed silica produced by Wacker, Germany, and stir for 10 minutes after addin...

Abstract

The invention discloses a manufacturing technology of a total-colloid superbattery. The manufacturing technology comprises a total-colloid electrolyte manufacturing technology, and a technology of a battery positive plate and a negative plate. Beneficial effects of the manufacturing technology of the total-colloid superbattery are that: the specific energy is high and can reach 40 W.H / KG, low temperature performances are good, the capacity at -18 DEG C reaches over 83%, the receptivity for quick charge is strong, the capacity can reach over 97% after quick charge for 1 H, and the service lifetime reaches more than 500 cycles.

Description

technical field [0001] The invention belongs to the field of battery production, and in particular relates to a production process of an all-gel super battery. Background technique [0002] Lead-acid battery (VRLA) is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is sulfuric acid solution. In the state of charge of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the discharge state, the main component of the positive and negative electrodes is lead sulfate. It has been used for nearly 200 years. It is stipulated that its capacity reaches 50% of the specified capacity at -18°C; for charging acceptance, fast charging 1H, international regulations must reach 80% of the specified capacity; international regulations must be greater than 400 cycles of service life. So far, there is no newer battery manufacturing technology to improve these ori...
