The OPzV series is suitable for environments with large temperature differences and unstable power grids, or renewable energy storage systems that are in an electric state for a long time. The colloid is formed by silicon particles with a very small body but a very large surface area. When the silicon particles are dispersed in the electrolyte, a three-dimensional chain network is formed, and a microporous system with a diameter of 0.1mm to 1mm is derived at the same time. Restricted by the powerful capillary phenomenon, the electrolyte is locked in the microporous system. Therefore, even if the battery casing is accidentally ruptured, electrolyte leakage will not occur. A small amount of micropores are not filled by the electrolyte, forming voids for oxygen to pass through. Oxygen migrates from the positive electrode to the negative electrode, and then recombines into water, thus eliminating the need to add water regularly.

OPzV battery has a long cycle life and floating charge life; it has better charge receiving capability and deep cycle performance; excellent under-charge and over-discharge cycle capabilities; excellent low-current charge-discharge performance; good high-temperature cycle performance; product design floating life of 20 years; using skeleton die-casting tubular plates, special separators, and fumed silica glue to delay grid corrosion, material softening, acid layering and other issues.
