Description

technical field [0001] The invention relates to the field of storage batteries, in particular to a storage battery with ultrasonic cavitation effect. 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 el...

Problems solved by technology

[0006] The purpose of the present invention is to solve the above problems and deficiencies, and provide a built-in ultrasonic ultrasonic solid-state lithium battery, which works by placing the ultrasonic vibration element inside the positive pole body and / or negative pole body and / or solid electrolyte. When it acts directly on the positive pole body and / or negative pole body and / or solid electrolyte, it promotes the molecular movement inside the positive pole body and / or negative pole body and / or solid electrolyte, and eliminates the Crystallization, and the passivation of the material molecular surface of the positive electrode body and / or the negative electrode body and / or the solid electrolyte, avoid affecting the mutual chemical reaction between the positive electrode body and the solid electrolyte, or the negative electrode body and the solid electrolyte, thereby improving and prolonging the solid state The service life of the lithium battery; moreover, the rapid movement of the material molecules brought by the ultrasonic vibration element can also accelerate the movement of the current electrons and improve the charging and discharging efficiency; and the movement of the current electrons is fast and smooth, which can also prevent the battery from bulging , explosion problems; and in the extremely cold environment, it can also assist the battery to heat up, solve the problem of low charging and discharging efficiency of the battery in winter, and can not work normally. In addition, it can also greatly reduce the complexity of the structure of the ultrasonic battery, so that it can be Lightweight and modular development
