Embodiment Construction

[0008] Below by embodiment, further illustrate the present invention and its beneficial effect.

[0009] Example 1, by weight percentage, add 1% super conductive carbon black and 2.5% colloidal graphite material to the positive electrode active material, (choose KS-15 special colloidal graphite material) add 1% potassium sulfate and 2 % of phosphoric acid, the compression ratio of the extreme group assembly is 62%, and the rest adopts the current lead-acid battery production technology to produce 16 2V300AH sample batteries. According to the capacity discharge voltage difference of 20mV and the terminal voltage of 10mV, 12 samples were selected from 16 samples to form two groups of A and B (6 samples in each group), and 100%DOD cycle life test was carried out at 25°C and 40°C, and the rest 4 (2 for each) were tested for overcharge and over-discharge resistance. And compared with the battery produced by the existing technology. The detection equipment adopts the 48V100A batte...

Abstract

The invention discloses a deep-cycle valve-control lead-acid storage battery. 1-2% of super electric conducting carbon black and 2-3% of colloidal graphite material are added into a positive electrode active material, and 0.5-1.5% of sulfate and 1%-2% of phosphoric acid are added into electrolyte, and the plate group assembled compression ratio is 60%-70%. According to the invention, excessive charging and discharging withstanding capabilities of the battery are improved, and high-temperature and normal-temperature cycle service lives of the battery are prolonged; the problems that the conventional lead-acid storage battery is easy to dehydrate at high temperature and the cycle service life is short are solved; and the valve-control lead-acid storage battery which is suitable for energy storage in deep cycle occasions is provided.

Description

technical field [0001] The invention relates to a deep-cycle valve-controlled lead-acid storage battery, which belongs to the field of lead-acid storage batteries. Background technique [0002] In the past ten years, valve-regulated sealed lead-acid battery technology has achieved great development and has been widely used in various industries, playing an important role in the rapid development of the national economy. At present, governments of various countries are vigorously developing solar and wind power generation, making full use of natural resources, realizing low-carbon circular economy, and maintaining sustainable economic development. Industry sectors are conducting in-depth research. The key technologies for the utilization of solar energy and wind energy have matured, so it is imperative to research and develop deep-cycle valve-regulated lead-acid batteries for energy storage. [0003] The existing lead-acid battery technology is mainly used in backup pow...
