Problems solved by technology

[0004] However, the currently used lead-carbon battery positive grid, due to the relatively obvious volume expansion of the positive plate of the battery during charging, and the occurrence of muddying of the positive plate of the battery, there are still the following problems:
[0005] 1. Weak charging acceptance;
[0006] 2. Short service life

Abstract

The invention discloses a graphene lead-carbon battery positive grid and a preparation method thereof. The graphene lead-carbon battery positive grid comprises a lead grid green body and graphene lead plaster covering the surface of the lead grid green body, and the graphene lead plaster is prepared from the following raw materials in parts by weight: 750 to 820 parts of sponge lead, 10 to 14 parts of barium sulfate, 1.4 to 1.8 parts of graphene, 0.75 to 0.85 part of polyacrylonitrile-based carbon fiber, 0.9 to 1.2 parts of carboxylated carbon nanotube, 60 to 90 parts of waterborne polyurethane, 0.7 to 0.9 part of isocyanate, 80 to 95 parts of dodecanol, 40 to 50 parts of isoprene glycol and 0.2 to 0.3 part of polyoxyethylene lauryl ether. The graphene lead-carbon battery positive plate grid is high in charging acceptance and long in service life, is superior to a common lead-carbon battery positive plate grid, and is obviously superior to a common lead-acid storage battery positive plate.

Description

Technical field[0001]The present invention relates to the field of electrochemical power supply, and more particularly to a graphene lead-carrying battery positive plate gate and a preparation method thereof.Background technique[0002]Lead-carbon battery (or lead carbon battery) is a capacitive lead-acid battery that is evolved from a conventional lead-acid battery, which is added to the negative electrode of the lead-acid battery, which can significantly improve lead acid. The life of the battery.[0003]The lead charcoal battery is a new type of super battery that combines both lead-acid batteries and supercapacitors: both playing the advantages of supercapacitance instantaneous capacity charging, but also played a lead-acid battery than energy advantages, and has very Good charge and discharge performance can be fully charged (lead-acid battery if this is allowed, the life is only less than 30). Moreover, due to the addition of carbon (graphene), the negative electrode sulfate is pr...
