Abstract
The invention discloses a high-performance high-current start-stop battery lead plaster. The high-performance high-current start-stop battery lead plaster comprises a positive electrode lead plaster and a negative electrode lead plaster, wherein the positive electrode lead plaster is prepared from the following components in percentages by weight: 0.1% to 1.0% of carbon fiber, 0.1% to 0.5% of graphene, 1.0% to 3.0% of graphite, 3.0% to 8.0% of 4BS seed crystal, 5% to 10% of dilute sulfuric acid, 0.01% to 0.1% of rare earth and the balance of lead powder; and the negative electrode lead plaster is prepared from the following components in percentages by weight: 0.1% to 1.0% of carbon fiber, 0.1% to 0.5% of graphene, 5.0% to 10% of active carbon, 5.0% to 10.0% of barium sulfate, 2.0% to 5.0% of humic acid, 1.0% to 5.0% of lignin, 5% to 10% of dilute sulfuric acid and the balance of lead powder. The cycle life of the battery can be prolonged, the battery capacity is increased, and the charging and discharging capacity of the battery is also maintained.
Description
Technical field [0001] The invention relates to the technical field of storage batteries, in particular to a high-performance high-current start-stop battery lead paste and a start-stop battery. Background technique [0002] Start-stop system battery technology is the top priority to promote the development of the new energy automobile industry. It requires lead-acid batteries with high current discharge performance, high charge reception performance, durability and strong cycle life. [0003] During the start and stop of the car, the battery is mostly used, usually a lead-acid battery, which provides a starting and ignition function. When encountering a red light or other road conditions, the car stops and shuts down the engine. When the green light is on, the car restarts, frequently starting and stopping. Reducing the service life of the battery, how to extend the service life of the battery, and how to recover the energy during the start of the car and start the ignition, brake...
