Problems solved by technology

Such a lead-carbon battery only changes the amount of carbon material in the lead paste, but does not change the basic composition of the negative plate, and the positive and vertical batteries still have the phenomenon of electrolyte concentration polarization inside the battery. The discharge rate performance is not high, and it cannot meet the requirements of high rate charge and discharge and long life of the battery in the field of new energy, electric power and communication / communication

Abstract

The invention discloses a horizontal lead carbon battery. A carbon-based negative pole plate is used as a negative electrode, a negative plate grid material is one of cadmium-free alloy or a carbon material, and a negative active substance is formed by mixing a lead compound and the carbon material or comprises the independent carbon material. A positive pole plate and the carbon-based negative pole plate in each single horizontal lead carbon battery are of horizontal structures, and a pole plate plane is parallel to a horizontal surface. By the preparation method of the negative pole plate and the composition structure of a single internal pole plate, the purpose of lead carbon battery design is achieved, the concentration polarization phenomenon of an electrolyte in the battery can be fundamentally and effectively prevented, the cycle lifetime of the battery is effectively prolonged, and the large-rate charge-discharge performance of the battery is effectively improved. The preparation method of the horizontal lead carbon battery is simple and convenient, is easy to operate and can be widely used for protection of the lead carbon battery.
