Abstract

The invention discloses a lead acid battery taking graphene as an additive, and relates to a lead acid battery technology. The lead acid battery comprises a battery shell, a positive plate grid, a negative plate grid, a partition board and electrolyte, wherein the positive and negative plate grids are positioned in the battery shell; the partition board is positioned between the positive and negative plate grids; and the electrolyte is filled into the shell. The lead acid battery is characterized in that: the positive plate grid is manufactured by coating cathode lead paste and performing curing, drying and formation; the negative plate grid is manufactured by coating anode lead paste and performing the curing, the drying and the formation; and the cathode lead paste or the anode lead paste or both take the graphene as the additive. The lead acid battery provided by the invention takes the graphene material as the additive, can be rapidly charged and discharged, and simultaneously has high capacity and relatively longer charging and discharging circulation service life.

Description

technical field [0001] The invention relates to lead-acid battery technology, in particular to a lead-acid battery using graphene as an additive. Background technique [0002] Lead-acid batteries have a history of 130 years. They have the advantages of reliable performance, mature production technology, and lower cost than nickel-metal hydride batteries and lithium batteries. The vast majority of current electric bicycles use sealed lead-acid batteries. The sealed lead-acid battery is to stack the positive and negative plates in the battery box, and the positive and negative plates are separated by insulating separators. When the electrolyte is charged into the battery box, the electrolyte and the positive and negative plates lead chemical reaction. When the battery is charged, the lead on the positive and negative plates that become lead sulfate releases the sulfuric acid component fixed in it into the electrolyte, and turns into lead and lead oxide respectively, so that ...
