Problems solved by technology

Since the density of carbon materials is much lower than that of lead powder, especially activated carbon and carbon black, there is a huge gap. If you add less, the advantages of carbon conductance and capacitance will not show. In addition, adding too much carbon material will occupy the space of lead powder, which will affect the capacity of the battery. During the battery cycle, the lead paste will fall off and reduce the battery life.

Abstract

The invention provides diachylon of a negative electrode of a lead carbon battery and a manufacturing method thereof, and relates to the field of manufacturing lead-acid storage batteries. Important improvement is as follows: a mixed carbon material and SiO2 are added into the diachylon, wherein the mixed carbon material consists of graphite, carbon black, active carbon and vapor grown carbon fiber which are mixed. As the mixed carbon material and SiO2 in scientific proportion are added, the contact resistance of active matters is reduced, and the conductivity is improved, and the polar plate connection is better. The diachylon is not loosened, so that the comprehensive performance of the battery is improved, and the diachylon is suitable for demand of novel energy industry and electromobile industry. The manufacturing method of the diachylon provided by the invention is simple and convenient to operate and normal, and the diachylon is excellent and stable in performance. The method is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of lead-acid storage battery manufacturing, and in particular relates to a lead-carbon battery negative electrode paste and a production method thereof. Background technique [0002] Due to the shortage of oil resources, serious environmental pollution and greenhouse effect, people pay more and more attention to the new energy industry and the electric vehicle industry, especially the storage battery, which is a device for energy storage and conversion. Considering the advantages and disadvantages of batteries, there are currently four key points: capacity, life, weight, and price. There are currently commercially available energy storage devices—batteries—each with its own advantages and disadvantages. [0003] Lithium-ion battery: light weight, long life, but high price, poor safety of large-capacity batteries; [0004] Ni-MH battery: light in weight, medium in life, but high in price and low in energy (...
