Embodiment

[0071]Select the Pb-Ca-Sn-Al continuous expansion positive electrode grid, according to the fixed lead paste formula (the formula contains a certain amount of red lead, ultra-fine 4BS seed crystals and special additives), using high temperature and high humidity (temperature 75 ℃, Humidity 98%) curing process, by changing the ratio of superfine 4BS and red lead, 4 kinds of positive plates were prepared, the specific scheme is shown in the following table:

[0072] standard sequence ω(4BS) / % ω(red lead) / % response variable plan 1 1.125 3.375 √ Scenario 2 0.750 6.250 √ Option 3 0.469 12.656 √ Option 4 0.625 12.500 √

[0073] 1. Physical and chemical parameters and structural analysis of the positive plate

[0074] 1.1. Positive plate drop strength test

[0075] First weigh the raw plate (with coated paper) and record it as m 0 , and then put the paste-coated side of the green plate down, and drop it freely from a height of 1 ...

Abstract

The invention relates to a method for researching the dynamic charging acceptance of an exhaust type start-stop lead-acid storage battery, which adopts a mass comparison method to purchase mainstream start-stop battery products on the market for testing the dynamic charging acceptance. And after a detection result is obtained, dissecting each battery, and analyzing the cycle life of the lead-acid storage battery from the electrochemical performance of the positive electrode of the battery. According to the invention, the market development of start-stop battery products is facilitated, the production and sales are standardized, the independent innovation ability of enterprises is enhanced, the economic benefits of new products are increased, and meanwhile, the pollution to the environment is reduced.

Description

technical field [0001] The invention relates to a method for researching the dynamic charge acceptability of a lead-acid storage battery for start-stop of an exhaust type. It belongs to the technical field of storage batteries. Background technique [0002] With the increasing number of cars and their wider use, car pollution has increasingly become a global problem, especially the fuel waste and exhaust pollution caused by cars idling, which has a particularly prominent negative effect on world energy and the environment. In our country, with the intensification of urbanization and the continuous increase of car ownership, traffic congestion in big cities has become an unavoidable reality. In China's large and medium-sized cities and some coastal cities, the average ratio of car driving time to idling time waiting for red lights or traffic jams is 3:1, and urban roads will become more congested as more than ten million new cars flock to the road every year. According to s...
