Embodiment Construction

[0008] Application of nano-silica colloids in the manufacture of lead-acid batteries. Using nano fumed SiO2 (Fureed SiO2), commonly known as white carbon black, the colloidal lead-acid battery made of it has excellent performance, mainly because the fumed silica has good purity and the particle size is easy to adjust, so the activity is good. After specific tests, the structure of the conventional VRLA battery is used, and the ordinary AGM glass fiber separator is used. The AGM separator is also SiO2 as the main component, which reacts with polar molecule H2O hydration and sulfuric acid and also acts as a catalytic carrier. Liquid-rich structure, a small amount of fumed silica and other trace active additives. You can get high-performance current output, excellent performance under deep cycle conditions, high power density, high charging efficiency (99.5%), overcharge resistance, good charging repeatability, good charging stability (anti-thermal runaway), As a battery in the ...

Abstract

The invention relates to a nano colloidal silica lead-acid battery, which prolongs the service life and increases the capacitance by overcoming the defect of early-stage capacitance loss of the lead-acid battery and belongs to the technical field of surface chemical and electrochemical kinetics. The accumulator is characterized in that the nano gas phase silicon dioxide (SiO2) (Fureed SiO2) (familiarly known as white carbon black) is applied to the regular valve-regulated lead-acid (VRLA) battery structure. The nano colloidal silica lead-acid battery is characterized by prolonging the service life and increasing the capacitance by overcoming three kinds of early-stage capacitance losses of the battery.

Description

technical field [0001] The invention relates to a nano-silica colloidal lead-acid storage battery, which solves the problems that the lead-acid storage battery overcomes early capacity loss to achieve long life and increase large capacity. The invention belongs to the technical field of surface chemistry and electrochemical power. Background technique [0002] Inorganic nano-silica colloid (Gelled) is a dispersed system, which is a special state of matter, rather than a special substance. The technical principle of the current colloidal lead-acid battery is not accurately positioned. Whether it is an electrochemical thermodynamic problem or an electrochemical kinetic problem, if the technical route of the colloidal electrolyte lead-acid battery is positioned, the basic principle cannot be explained because it does not participate in the flow chemical reaction. The correct one is to use the basic principle of surface chemistry to explain it in terms of electrochemical kineti...
