Problems solved by technology

The external parallel type is mainly to add a capacitor outside the battery, which acts as a charge buffer and memory when the battery is charged and discharged. This method needs to add additional electrical components, and the cost of the battery is relatively high; the internal hybrid type is mainly to mix the capacitor material into the battery. into the battery electrode material to make a capacitive battery plate, its biggest advantage is that it can effectively delay the salinization of the negative plate of the battery, but the plate produced by this method cannot guarantee that the plate has a high The amount of carbon is difficult to play the role of a charge buffer, and the addition of carbon materials will lead to the intensification of hydrogen evolution on the plate; the i

Abstract

The invention discloses a preparation method of super storage battery lead-carbon negative plate. The method comprises the following steps of: firstly, mixing and evenly stirring the carbon, the additive and the water, filtering under vacuum condition, adding binder diluents and stirring evenly to obtain the carbon paste; evenly spreading the carbon paste on two sides of a raw lead-carbon negative plate, then, tightly wrapping the negative plate coated by the carbon paste with a coating paper, applying pressure on the negative plate for compaction, then, drying the compacted negative plate for 1-2 hours at the temperature of 45-120 degrees centigrade, and obtaining a lead-carbon negative plate with bipolarity of 'battery character' and 'capacitive character'. In comparison with the method of gouging a part of the lead paste on the negative plate and substituting the gouged part by the carbon paste, the method provided by the invention is convenient to operate and easy to carry out, and simultaneously, avoids bad influence on the battery performance caused by directly adding a carbon plate in the battery, so that the prepared super storage battery is high in performance and long in service life. The method provided by the invention is strong in operability, suitable for bulk production in workshops and extremely low in cost in comparison with the external parallel type super battery.

Description

technical field [0001] The invention relates to the field of storage battery production, in particular to a method for preparing a negative plate of a super storage battery. Background technique [0002] Today's lead-acid battery industry has developed innovatively, combining supercapacitors with existing batteries, so that the high-power characteristics of supercapacitors and the high energy density characteristics of batteries can be concentrated. [0003] The super batteries currently researched are mainly divided into three categories: external parallel type, internal hybrid type, and internal parallel type. The external parallel type is mainly to add a capacitor outside the battery, which acts as a charge buffer and memory when the battery is charged and discharged. This method needs to add additional electrical components, and the cost of the battery is relatively high; the internal hybrid type is mainly to mix the capacitor material into the battery. into the b...
