Shenzhen Maintenance-Free Gel Battery Wholesale, Shenzhen Maintenance-Free Gel Battery Price, Shenzhen Maintenance-Free Gel Battery Manufacturer [Shenzhen Nuonai Power] - The Maintenance-Free Gel Battery is an improvement on the basic principles of maintenance-free batteries, enhancing the electrolyte used in battery construction. Utilizing nano-aerosol SiO2 (Fureed SiO2), commonly known as white carbon black, the gel lead-acid batteries produced are of high quality, primarily due to the purity of the gas-phase silicon dioxide and its ease of particle size adjustment, resulting in excellent activity. Employing the conventional VRLA battery structure with standard AGM glass fiber separators, where the AGM separator is primarily composed of SiO2 and serves as a catalyst carrier through hydration and reaction with polar molecules H2O. The rich-liquid structure incorporates a small amount of gas-phase silicon dioxide and other trace active additives. This results in high-performance current output, excellent performance under deep-cycle conditions, high power density, high charging efficiency (99.5%), resistance to overcharging, good charging reproducibility, and stability (resistance to thermal runaway). As a battery in power systems, it is required to be maintenance-free throughout its lifespan, with long life, wide operating temperature range, low watt-hour pricing, superior volumetric energy density, high energy density by weight, and low self-discharge rate.
