Abstract

The invention discloses lead carbon battery cathode diachylon. The lead carbon battery cathode diachylon is prepared from raw materials of 100 parts of lead powder, 4-100 parts of sulfuric acid, 0.1-8 parts of bonding agents, 0.1-2 parts of barium sulfate, 0.01-2 parts of hydrogen evolution inhibitors, 50-100 parts of graphene oxide, 0.05-1 part of acetylene black, 1-4 parts of humic acid, 5-15 parts of red lead, 12-21 parts of water and 0.1-0.2 part of short fibers. The invention also discloses a preparation method of the cathode diachylon as well as a lead carbon battery cathode comprising the diachylon as well as a preparation method of the lead carbon battery cathode and a lead carbon battery. According to the invention, graphene oxide is added into the cathode diachylon; graphene oxide contains a plurality of oxygen-containing functional groups, and a plurality of faradaic pseudocapacitance can be generated in sulfuric acid, so that the using quantity of lead powder in the cathode material can be reduced; meanwhile, electricity of the lead cathode can be shared under the condition of high-current charge and discharge; sulfation of a storage battery is relieved greatly; the service life of a storage battery is prolonged.

Description

technical field [0001] The invention relates to the field of electrochemical power sources, in particular to a lead-carbon battery negative electrode paste and a preparation method thereof, a lead-carbon battery negative plate and a lead-carbon battery. Background technique [0002] A lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. Since the invention of lead-acid batteries by the Frenchman Plante in 1859, lead-acid batteries have experienced more than 150 years of development. Lead-acid batteries have low cost, long life, good safety performance, and the recycling rate of waste batteries is as high as 95%. Therefore, it has always been the most widely used product in the battery field. [0003] With the rapid development of electric vehicles and electric bicycles, a new battery based on lead-carbon technology has gradually emerged, that is, lead-carbon batteries. This battery adds acti...
