Abstract

The invention relates to a production method of a composite negative electrode of a lead-acid battery, belonging to the field of electrochemical power sources. In the production process of lead-acid battery composite plates, after the negative plate grid is coated with lead paste on the negative plate, it directly enters the capacitor layer coating process, and then the plate is cured and dried. This process improves the composite plate. It not only improves the performance of lead-acid batteries, but also simplifies the production process of composite plates and improves production efficiency.

Description

technical field [0001] The invention belongs to the field of electrochemical power sources, and belongs to the improvement technology of the negative plate of the lead-acid battery. The lead-acid battery prepared by the composite negative plate provided by the invention is suitable for hybrid vehicles, wind turbines and solar power generation which are repeatedly and rapidly charged and discharged in a partially charged state PSOC Industrial applications such as energy storage. Background technique [0002] With the introduction of the national new energy strategy, various automakers have begun to pay more attention to the research and development of hybrid vehicles, and the country has also increased its support for wind and solar off-grid grid-connected energy storage. Currently commonly used and relatively mature batteries are mainly divided into lithium-ion batteries, nickel-metal hydride batteries and lead-acid batteries. Compared with the first two batteries, lead-acid...
