Ultrasonic storage battery

Abstract

The invention relates to an ultrasonic storage battery which is characterized in that an electrolyte specific gravity sensor and a liquid level sensor are installed inside a conventional lead-acid storage battery, a current sensor is installed on a storage battery connecting pile, the side surface of the storage battery is provided with an ultrasonic transducer, the electrolyte specific gravity sensor, the liquid level sensor, the current sensor and the ultrasonic transducer are connected with a controller through a conducting wire, and the controller is connected with the exterior of the storage battery through a data bus so as to transmit the data of the storage battery. According to the ultrasonic storage battery, when the drive current is outputted through the ultrasonic transducer, the ultrasonic wave is applied to the inside of the storage battery, the concentration gradient of the electrolyte nearby a polar plate can be efficiently reduced through the ultrasonic effect, the chemical reaction of a solid-liquid interface nearby the polar plate can be accelerated, and large lead sulfate crystals formed in the chemical reaction process can be prevented and even eliminated, so that the large-current charging and discharging can be carried out for a long time, and the cycling life is greatly prolonged compared with the conventional storage battery.

Description

technical field [0001] The invention relates to an ultrasonic accumulator. Background technique [0002] Lead-acid batteries have the advantages of low price, reliable use, and large current discharge, and are still the most used high-power batteries, especially energy storage batteries. However, the Achilles' heel of lead-acid batteries is low specific energy, few charge and discharge cycles and serious environmental pollution. Under normal circumstances, the life span is no more than two years. [0003] With the large-scale use of new energy sources such as wind energy and solar energy, large-scale electric energy storage has become a technical bottleneck. Only by storing the electric energy generated by unstable clean energy in the form of electricity, and then sending it into the grid according to the scheduling instructions, can it finally meet the scheduling requirements of the grid. Therefore, developing high-power, long-life energy storage batteries and breaking t...

Problems solved by technology

[0009] After the battery is discharged, the active substances at both poles are converted into lead sulfate. When the lead-acid battery is repeatedly charged and discharged or over-discharged, thick and hard lead sulfate crystals will be formed on the negative electrode. This lead sulfate cannot be dissolved by overcharging, resulting in electrolyte The density is lower than the normal value, the battery cannot be charged and fails
