Abstract

The invention discloses an efficient processing technology for a lead-acid rapidly-charged battery. The efficient processing technology comprises the steps of mixing 800kg of lead powder and 200kg of carbon, performing dry mixing uniformly on the mixture; then adding 100kg of pure water and 90kg of 1.40g / ml dilute sulfuric acid, and stirring to obtain lead paste, filling and coating a wet polar plate with the obtained lead paste; and carrying out pore-opening, curing and drying and battery formation on the filled and coated wet polar plate; and then performing an assembling and manufacturing procedure on the lead-acid battery. The invention aims to provide a processing technology for producing the lead-acid storage battery which is matched with traffic tools and capable of stratifying long-journey traveling requirement, and can be rapidly and continuously charged in a cyclic manner.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a process technology of adding carbon materials, positive and negative plate openings and structures thereof to positive and negative active materials of lead-acid fast charging batteries. Background technique [0002] Lead-acid batteries have a history of 100 years, with reliable performance and mature production technology. Most of the current electric bicycles use sealed lead-acid batteries. When the battery is charged, the lead paste on the positive plate is converted into lead dioxide, and the lead paste on the negative plate is converted into spongy lead. When the battery is discharged, the active material on the positive plate is converted into lead sulfate, and the active material on the negative plate is also converted into lead sulfate. , so the cycle charge and discharge of the battery is a process of continuous conversion of electrical energy and chemical ...
