WATER-BASED ADHESIVES: INTERMEDIATE PRODUCTS IN GEL BATTERIES
The history of gel batteries is related to the development of colloidal materials and the maturity of the technology. In the past three or two years, although nano-scale sols have been developed and more production practices have been carried out for the electrochemical application of surfactants, it is difficult for manufacturers to select suitable gel colloids in a short period of time. The most important features of gel batteries are as follows:
1. The interior of the colloidal battery is mainly SiO2 porous network structure, and there are a lot of tiny gaps, which can 2. Make the oxygen generated by the positive electrode of the battery migrate smoothly to the negative electrode plate, which is convenient for the negative electrode to absorb and combine;
3. The amount of acid carried by the colloidal battery is relatively large, so its capacity is basically the same as that of the AGM battery;
4. The internal resistance of the colloidal battery is relatively large, and generally, it does not have good high-current discharge characteristics;
5. The heat is easy to diffuse, not easy to heat up, and the probability of thermal runaway is very small
The water-based glue design is an intermediate product developed from an acid battery to a colloidal battery. It is characterized by: canceling the physical gelling skeleton, retaining the functional polymer group characteristics and surfactants, pure liquid, and is regarded as a kind of sulfuric acid when used. Additive, suitable for making all lead-acid batteries.
Its advantage is that it does not cause the common industrial problems of colloidal batteries. The manufacturing process is exactly the same as that of acid batteries. After use, the capacity is increased by 5-15%, the battery life is prolonged by 50-100%, and the anti-plate sulfation ability is strong. The corrosion force to the grid is much less after the corrosion. The price is also cheaper than conventional colloids. After using the water-based glue additive, there is no need to add sodium sulfate, phosphoric acid, etc. to the sulfuric acid.
