Abstract

The invention discloses a method for preparing a nano high-energy maintenance-free lead-acid battery, which comprises the following steps: (1) forming superfine glass fiber layers on the surfaces of grids made of a nano ceramic powder and lead metal powder material, coating a layer of uniform lead plaster on each superfine glass fiber layer, stacking a plurality of polar plate units formed by the grids, lead paster and the superfine glass fiber layers to form a layered structure and making a battery core; (2) making electrodes by using two groups of single magnet materials, and placing two groups of electrodes in the left and right ends of the battery; and (3) mounting a battery box, a box cover and terminals. In the invention, the use of the nano ceramic grid can effectively improve the mechanical strength of polar plates and improve the conductivity of the polar plates; as the signal magnet material is used as the connecting material for the polar plates, the charging time is reduced effectively and the charging efficiency is improved; in addition, due to the adoption of the composite grids, the components participating in electrochemical conversion are increased effectively and thus the capacity of the storage battery is improved considerably.

Description

technical field [0001] The invention relates to a preparation method of a nanometer high-energy maintenance-free lead-acid storage battery. Background technique [0002] In recent years, with the rapid development of automobile industry, telecommunications and IT network and other infrastructure, power vehicles and renewable energy industries, the lead-acid battery and its battery industry as the first choice have developed rapidly. Due to the increasing demand for lead-acid batteries in the international market, developed countries such as the European Union and the United States have already restricted the production of lead-acid battery manufacturing in their own countries out of the sensitivity to protect their own environments, and turned to purchasing from developing countries. China has become one of the world's largest exporters of lead-acid batteries. With my country's increasing emphasis on new energy sources, safe, efficient and energy-saving lead-acid batteries ...
