Problems solved by technology

For example, L.T.Lam et al. have made a supercapacitor, the positive pole is a conventional lead dioxide plate, and the negative pole includes a parallel carbon electrode and a lead electrode. However, the supercapacitor uses a large number of grids, which increases the weight of the battery
D.Pavlov et al. added activated carbon, carbon black and other materials to ordinary lead paste, and the super battery they made could be charged and discharged with 2C current at 50% state of charge (SOC) and 3% depth of discharge (DOD), but The battery is suitable for hybrid vehicles, but not suitable for solar and wind energy requirements for cycle life and rate performance in the HR-PSOC state of the battery

Abstract

The embodiment of the invention provides a lead carbon battery negative pole plate. The lead carbon negative pole plate comprises a grid, lead paste and a non-grid fabric patch, wherein the lead paste is coated between the grid and the non-grid fabric patch so that the grid and the non-grid fabric patch are glued to form a three-layer structure comprising the grid, the lead paste and the non-grid fabric patch. In the lead carbon battery negative pole plate provided by the embodiment of the invention, the lead paste and the grid, the lead paste and the lead paste and the lead paste and the non-grid fabric patch are firmly combined, the stability of a battery in a high-rate partial state of charge (HR-PSOC) and in frequent charge-discharge usage can be remarkably improved, an instantaneous large current is effectively buffered, sulfation on a surface of a negative electrode is prevented, the charge acceptance capability of the battery is remarkably improved, and the cycle property and the rapid charge-discharge characteristic of the battery under the HR-PSOC are substantially improved. The embodiment of the invention also provides a preparation method of the lead carbon battery negative pole plate and a lead carbon battery.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a lead-carbon battery, a lead-carbon battery negative plate and a preparation method thereof. Background technique [0002] With the rapid development of the global economy and society, the increasing shortage of energy, the deteriorating ecological environment, and the sharp increase in environmental protection pressure, people will rely more on renewable resources such as solar energy and wind energy. However, the energy generated by solar energy and wind energy cannot be directly connected to the grid. It is necessary to use energy storage technology (device) to store the energy first, which requires the use of batteries to store the energy. At present, commonly used and relatively mature batteries are mainly divided into lithium-ion batteries, nickel-hydrogen batteries and lead-acid batteries. Compared with the first two batteries, lead-acid batteries still have great advantages in ...
