Recently, the enterprise technology innovation project undertaken by JBSK Company, “Development of Nano Fumed Silica for Colloidal Battery”, was accepted by relevant experts organized by China Science and Technology Bureau.
Colloidal battery is an improved model of lead-acid battery. It replaced colloidal electrolyte with sulfuric acid electrolyte. It has improved safety, storage capacity, discharge performance and service life compared to ordinary batteries. Adding water to supplement the electrolyte is also called maintenance-free battery. Fumed silica, as a key gelling agent, has been widely used in colloidal batteries in recent years. In addition, high-quality fumed silica does not contain impurities, has high surface activity and strong gelling force; furthermore, high-quality colloids can evenly distribute the electrolyte, and there is no acid layering phenomenon.
It is reported that the project has built a production line for 1000 tons of colloidal nano-silica batteries, applied for 2 patents, obtained 2 authorized patents, published 2 papers, and added sales of 8.447 million yuan. The completion of the project ended The high-tech field of colloidal storage battery fumed silica has monopolized China's monopoly position, and has realized the localization of colloidal storage battery fumed silica. It has rapidly shortened the gap between China and foreign advanced production levels, and will greatly improve China's nano-phase fumed silica. The manufacturing level of silicon oxide simultaneously solves the problem of high production cost of colloidal batteries in China, and will also promote the development of China's nano-phase fumed silica industry and the development of organic silicon monomer industry, which is of great social significance.
