Problems solved by technology

[0004] There are mainly four types of existing internal integration technologies: one is to replace part of the lead paste on the plate with carbon paste, but it is complicated and cumbersome in industrial production operations; the other is to directly replace the battery plate with a pure carbon plate, But this kind of method has reduced the capacity of accumulator; The 3rd, the carbon paste that will be added with binding agent is coated on the both sides of accumulator conventional coating lead plaster pole plate, but the carbon paste layer that this kind method coats is easy to loosen; The fourth is to coat the carbon paste with binder on one side of the bipolar plate substrate, so that one side of the polar plate substrate is coated with a lead paste layer, and the other side is coated with a carbon paste layer, and the lead paste, carbon paste Isolation by the plate matrix can achieve bipolar effect, but the plate matrix alloy used in this method is more expensive, the cost is high, and the independently coated carbon paste layer is easy to loosen and detach

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see figure 1 , figure 1 It is a schematic diagram of the structure of the negative plate disclosed in the embodiment of the present application.

[0021] Such as figure 1 as shown, figure 1 The grid base (1) of the neutral plate is a perforated grid, which adopts a fully automatic continuous casting and rolling punching process, and the amount of alloy material in the grid base (1) is lower than that of the bipolar plate base , taking into account t...

Abstract

The invention discloses a negative electrode plate comprising a grid substrate disposed inside a battery casing, and a front paste layer and a back paste layer coating the front and back sides of thegrid substrate respectively, wherein the grid substrate is a punched grid, the front paste layer and the back paste layer are wrapped in a composite separating plate. The negative electrode plate haslow cost and a firm carbon paste layer, and can ensure that a super battery has good capacity and high production operation efficiency. The present invention also discloses a super battery including the negative electrode plate.

Description

technical field [0001] The invention relates to the technical field of power supply manufacturing, in particular to a negative plate. The present invention also relates to a super battery comprising the above-mentioned negative plate. Background technique [0002] Today, technological innovations in the fields of new energy at home and abroad are developing rapidly in the fields of energy storage, communication, and power, and the technical research on storage batteries is also gradually deepening. The requirements for high-current discharge and fast charging of storage battery products for customers are also gradually increasing. When a traditional battery is used in parallel with a supercapacitor, the high power characteristics of the capacitor and the high energy density characteristics of the battery can be embodied in a concentrated manner. When the battery is charged and discharged, the supercapacitor acts as a charge buffer and memory, eliminating the sharp pulse disc...
