Problems solved by technology

Since the grid of the battery is mostly made of lead-calcium alloy, when the battery is working at a high current, the current is unevenly divided on the grid, and the utilization rate of the active material is inconsistent. The utilization rate of the active material in the upper part is high while the utilization rate of the active material in the lower part is relatively low. Serious delamination of the electrolyte, poor charge and discharge performance at low temperature, especially in winter, the disadvantage of insufficient charge, the battery is in deep discharge for a long time during use, and the service life of the battery is short

Abstract

The invention discloses functional polymer nanometer electrolyte and a method for preparing the same. The electrolyte is mainly prepared by the following compositions which are mixed together in percentage by weight that: 1.9 to 2.8 percent of jellies, 0.7 to 0.8 percent of stabilizing agent, 0.6 to 0.8 percent of complexing agent, 0.5 to 0.6 percent of surface active agent, 39 to 43 percent of sulfuric acid, the balancing being water. The functional polymer nanometer electrolyte and common electrolyte are mixed and added to a lead-acid accumulator; after being charged, the accumulator electrolyte is of a gel shape and forms a stable colloid, thereby effectively solving the problem of the electrolyte delamination in the prior art, improving the low-temperature charging and discharging performance of the accumulator and prolonging the life-span of the accumulator.

Description

technical field [0001] The invention relates to an electrolyte solution of a storage battery, in particular to a functional polymer nano electrolyte solution of a valve-controlled sealed lead-acid energy storage battery and a preparation method thereof. Background technique [0002] Valve-regulated sealed lead-acid energy storage batteries are mainly used in solar photovoltaic system engineering, and sulfuric acid electrolyte is generally used as the core battery for energy exchange. Since the grid of the battery is mostly made of lead-calcium alloy, when the battery is working at a high current, the current is unevenly divided on the grid, and the utilization rate of the active material is inconsistent. The utilization rate of the active material in the upper part is high while the utilization rate of the active material in the lower part is relatively low. This leads to serious stratification of the electrolyte, poor low-temperature charge and discharge performance, and th...
