Embodiment Construction

[0022] figure 1 Middle is the structural outline drawing of the negative electrode plate of the super battery of the present invention. The front of the alloy plate substrate 2 is coated with a front coating 1 (negative electrode paste coating layer) mainly composed of lead powder, and the back of the alloy plate substrate 2 is coated with a carbon material coating 3 mainly composed of carbon materials. The alloy plate substrate 2 has a thickness of 0.05-0.5 mm.

[0023] An alloy plate with a thickness of 0.05-0.5 mm is selected as the substrate 2, and the active ingredient front coating 1 mainly composed of traditional negative electrode paste is sprayed (or rolled) on the front of the substrate 2, and the carbon material mainly composed of carbon materials is coated. Layer 3 is sprayed (or drawn) on the back of the substrate, and the product of the present invention is alternately assembled with the positive plate of a traditional lead-acid battery to form a finished super ...

Abstract

The invention relates to a superbattery negative plate and a manufacturing method thereof. A front surface coating adopting lead powder as a main component is coated on the front surface of a substrate, and a carbon material coating is coated on the back surface of the substrate. The front surface coating comprises the following components by weight percent relative to the content of the lead powder: 0.2 to 2.0(wt)% of acetylene black, 1.0 to 2.0 (wt)% of barium sulfate, 0.2 to 0.5 (wt)% of lignin, 0.3 to 0.5 (wt)% of humic acid, 0.1 to 0.8 (wt)% of short fibers and 1 to 5.0(wt)% of adhesives. The carbon material coating 3 comprises the following components by weight percent: 65 to 90(wt)% of carbon material, 5 to 25(wt)% of acetylene black and 1 to 10(wt)% of adhesives. The carbon layer having a double-electric-layer structure is introduced onto the traditional storage battery negative plate, so that the superbattery has high specific power and can be charged and discharged at a large current, the sulfation of the lead paste on the front surface of a cathode at the HRPSOC (high-rate partial state of charge) state can be reduced, and the HEV (hybrid electrical vehicle) application can be met.

Description

technical field [0001] The invention belongs to the technical field of lead-acid batteries, and in particular relates to a novel super lead-acid battery negative plate structure. Background technique [0002] Transportation is one of the main contributors to human-generated greenhouse gas emissions and the burning of fossil fuels. Therefore, there is an increasing demand for hybrid electric vehicles (HEVs) to reduce air pollution and the use of fossil combustion. A super battery is a hybrid energy storage device that combines an asymmetric supercapacitor and a lead-acid battery in a single unit. It takes the advantages of both technologies and does not require additional electronic regulation. Capacitors can increase the power and life of lead-acid batteries because they act as a buffer during charge and discharge and can effectively avoid sulfation of the negative electrode. Moreover, this hybrid technology can quickly provide and absorb charge when the vehicle accelerate...
