Abstract
The invention discloses a long-service-life lead-acid storage battery which comprises a housing, a cathode plate, an anode plate and an electrolyte, wherein the anode plate comprises an anode plate grid and an anode active material, wherein a preparation method of the anode active material comprises the following steps: uniformly mixing lead powder, aluminum phosphate, an expanding agent and deionized water, heating to 90 DEG C to 95 DEG C, insulating for 1-2h; then raising the temperature to 120 DEG C and drying for 6h; raising the temperature to 240-260 DEG C, and microwavedrying for 3-6h; and air-cooling, and grinding into powder to prepare the cathode active material. Compared with a conventional lead-acid storage battery, the long-service-life lead-acid storage battery has the advantages that the 10h-rate capacity of the battery is improved by 10-17 percent, the high-rate cycle life of the battery is prolonged by above 30 percent; the 3h-rate capacity of the battery is increased by 9-147 percent, and the 3h-rate discharge cycle life of the battery is prolonged by above 30 percent.
Description
technical field [0001] The invention relates to a lead-acid storage battery, in particular to a long-life lead-acid storage battery. Background technique [0002] Existing lead-acid batteries are widely used in various fields of industry and agriculture, and are the main power source of electric vehicles at present. The disadvantages of its traditional lead-acid battery are: low specific energy, short cycle life, thermal runaway, bulky battery, low discharge efficiency at high rates, high temperature and low temperature have a great impact on battery performance, high temperature is easy to fail, and low temperature is minus 30 degrees The ability to charge and discharge is lost, and the active material is easy to fall off, resulting in a short service life. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a long-life lead-acid battery with long cycle life and high battery capacity, which...
