Description
Technical Field
The invention relates to a preparation method of a suspension stable type colloid electrolyte with high heat dissipation performance, and belongs to the technical field of electrolyte preparation.
Background
The lead-acid storage battery has been invented for over 150 years, and is widely applied to national economy and life of people due to the characteristics of high safety, stable performance, low manufacturing cost and high recycling value. The lead-acid accumulator consists of positive and negative plates, partition board, sulfuric acid electrolyte, accumulator cover and other parts. Because the traditional lead-acid storage battery adopts sulfuric acid as electrolyte, the sulfation of the pole plate can occur in the production process, and meanwhile, the self-discharge is large, the low-temperature performance is poor, the service life is short, and the use is limited.
The colloid lead-acid storage battery is a great innovation and improvement of a common lead-acid storage battery, and is widely applied to power supply systems in the fields of solar energy and wind energy off-line systems, electric power, telecommunication, communication, military communication stations, electric vehicles and the like. The electrolyte of the colloid lead-acid storage battery mainly comprises sulfuric acid and a gelling agent and has thixotropy. The gel agent forms a hydrogen bond through hydroxyl on the surface of the gel agent, forms a three-dimensional network structure in a system, and wraps sulfuric acid and water in the three-dimensional network structure, so that the colloidal electrolyte is solid when standing still. When a certain shearing force is applied, the three-dimensional network structure is rapidly disintegrated, and the colloid electrolyte is in a water solution state. When the shearing force stops, the colloid electrolyte is still kept to be recovered to the original solid state. The thixotropy endows the colloidal lead-acid storage battery with the advantages of convenient transportation and difficult liquid leakage.
At present, the most used gelling agent in the Chinese market is mainly silica sol. However, when the colloidal lead-acid storage battery using silica sol as a gel agent is charged/discharged, particularly when deep discharge occurs, the electrolyte is switched between a colloidal state and an aqueous solution state, and the colloidal electrolyte is easy to generate a hydration delamination phenomenon, so that the internal resistance of the battery is large, the service life of the battery is short, and the long-term service performance of the battery is seriously influenced.
Therefore, the preparation method which can greatly improve the service life and the service performance of the silica sol gel battery and meet the use requirement is the problem to be solved by the invention.
