Regenerated lead acid batteries and method

Abstract

The invention provides a regeneration lead-acid battery and a regeneration method, which belong to a field of the lead-acid battery. The regeneration lead-acid battery includes a lead-acid battery characterized in that: as for a scraped lead-acid battery with battery capacity less than 60-90 percent of a rated value, an anode is taken as a cathode, while a cathode is taken as an anode, and thus the anode and the cathode are exchanged with each other and are connected with a load. The regeneration method includes the processes: (1) the capacity of the battery is discharged to 0 voltage before the anode and the cathode are exchanged and connected with each other; (2) when the battery capacity reaches 60 to 90 percent of the rated value, the anode and the cathode are exchanged with each other; (3) current charging is carried out by applying the rated capacity of the battery of 10 hours-rate; (4) when the charging voltage reaches the rated value, the battery is stabilized for 3-5 hours. The invention allows the scraped battery to regenerate. Since the invention saves resource and raw material in great quantity, prevents environment pollution and at the same time reduces the cost, the invention is technically beneficial for both the country and the people.

Description

technical field [0001] The invention discloses a method for regenerating a lead-acid storage battery, which belongs to the field of lead-acid storage batteries. Background technique [0002] The current power system regulation stipulates that when the capacity of the lead-acid battery is lower than 80% of the rated value, the battery should be discarded. It can prolong the service life of the battery by more than double. However, because repeated charging accelerates the corrosion and aging of the positive plate, the battery can be extended for about one year at most. Simultaneously other departments, the industry that uses large-scale lead-acid storage battery, and civil use such as electric bicycle, motorcycle etc. also have above-mentioned problem, and battery service life is short, both wastes energy, causes environmental pollution again. A better method for solving the above-mentioned problems in the prior art has not been found yet. Contents of the invention [00...

Problems solved by technology

However, because repeated charging accelerates the corrosion and aging of the positive plate, the battery can be extended for about one year at most.

At the same time, other departments, industries using large lead-acid batteries, and civilians such as electric bicycles and motorcycles also have the above-mentioned problems. The battery life is short, which wastes energy and causes environmental pollution.

Have not found the better method that solves above-mentioned prior art problem at present
