NYS6-2S-AGM separator nano-silica aqueous dispersion
NYS6-2S is an aqueous dispersion prepared from undried nano-silica cake with small particle size and ultra-high specific surface area independently developed and produced by our company through high-speed pre-dispersion treatment. The surface of the product is rich in hydroxyl groups and the pore size remains intact. , with ultra-high specific surface area and strong activity. The product does not need to be pre-treated before use. An appropriate amount is added to the AGM separator paper to prepare an AGM separator with a high specific area. The specific surface area of the AGM separator is ≥5m2/g and the pore diameter is ≤13um. In this high-specific-area AGM separator, nano-silica particles easily form network spaces and can be closely combined with glass fibers to form a uniform and stable three-dimensional network structure, which overcomes the powder falling phenomenon of traditional silica-prepared separators. ; At the same time, it can improve the stability and uniformity of the colloidal network structure of the AGM separator, improve the electrolyte stratification phenomenon inside the battery, enhance the wet elasticity of the separator, and effectively solve the problems of low wet elasticity and poor assembly pressure retention ability of the AGM separator. ; The pore size of the AGM separator prepared by this product is greatly reduced, which can further improve the prevention performance of micro-short circuit caused by dendrite puncture, slow down the capacity decline of the battery, and extend the cycle time of the battery.

When the amount of nano-silica is added to more than 2%, separator paper for dissolvable colloidal batteries can be prepared. After charging and discharging cycles ≥ 10 times, the dissolution amount of nano-silica is ≥ 50%, and the dissolved nano-silica gradually forms a gel, thus The formation of an all-solid gel battery opens up a new manufacturing method of gel batteries, eliminating the need to add glue to lead-acid batteries, and solving problems such as the difficulty of adding glue to lead-acid batteries and uneven formation within the battery.
