An ultrasonic lead-acid battery

Abstract

The invention relates to an ultrasonic lead-acid storage battery, which includes a battery case, a battery cover, a cluster group, and at least one ultrasonic transducer. A receiving chamber is opened on the top of the battery case, and a liquid discharge port penetrating into the receiving chamber is provided on the outer wall of the battery case. , there is a sealing plug in the drain port, and a number of insulating and corrosion-resistant vibrating strips are installed at the bottom of the battery cover. The cluster group includes a number of positive plates, a number of negative plates, and a number of separators. The separators are respectively arranged between the positive electrode plate and the negative electrode plate, the clusters are arranged in the accommodation cavity, and the vibrating strips are respectively inserted between the positive electrode plate and the separator, and between the negative electrode plate and the separator, and the ultrasonic transducer is set on top of the battery cover. By using high-frequency ultrasonic vibration to prevent lead sulfate crystals on the surface of the battery plate, to maintain full and comprehensive contact between the battery plate and the electrolyte, it can greatly alleviate the attenuation of the storage performance of the battery and prolong the service life of the battery.

Description

technical field

[0001] The invention relates to the technical field of accumulators, in particular to a lead-acid accumulator. Background technique

[0002] A lead-acid battery is a battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution. In the discharge state of the lead-acid battery, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charging state, the main component of the positive and negative electrodes is lead sulfate. In existing lead-acid batteries, lead sulfate crystals will adhere to the surface of the electrode plate after the battery has been used for a certain period of time. With the increase of lead sulfate crystals, it will hinder the contact between the electrode plate and the electrolyte, thereby affecting the lead-acid battery. Storage performance, charge and discharge performance. Over time, the electrode plates of the l...
