Technical Field

The invention relates to the field of storage batteries, in particular to a storage battery with an internal ultrasonic cavitation effect.

Background

A lead-acid battery is a storage battery with electrodes mainly made of lead and its oxides and electrolyte solution of 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 a charged state, the main components of the positive electrode and the negative electrode are lead sulfate. In the existing lead-acid battery, after the battery is used for a period of time, lead sulfate crystals are attached to the surface of an electrode plate, and along with the increase of the lead sulfate crystals, the contact between the electrode plate and an electrolyte is obstructed, so that the storage performance and the charge and discharge performance of the lead-acid battery are influenced. Over time, the electrode plates of the lead-acid storage battery are not completely worn, and the lead-acid storage battery cannot store electricity and charge and discharge electricity.

For the lead-acid battery, the applicant proposes a technical scheme with patent application number 201811098611.9 and named as "an ultrasonic lead-acid battery" to the national intellectual property office in 2018, 09 and 20, and the technical scheme mainly comprises a battery shell, a battery cover, a collection group, an ultrasonic transducer, a vibrating strip and the like. This scheme installs ultrasonic transducer at the battery top, and the vibration strip inserts the clearance between positive plate and the baffle, and between negative plate and the baffle, utilizes ultrasonic transducer during operation, and the drive vibration strip is made high frequency ultrasonic wave motion, prevents that there is the lead sulfate crystallization on battery polar plate surface, makes and keeps abundant, comprehensive contact between battery polar plate and the electrolyte, can greatly alleviate the decay of battery storage performance, prolongs the life of battery. Although the technical scheme greatly relieves the attenuation of the storage performance of the storage battery and prolongs the service life of the storage battery compared with the traditional lead-acid storage battery, the complexity and the volume of the battery structure are increased to a certain extent along with the attenuation, and the technical scheme is not an optimal solution.

The lithium ion battery mainly comprises a positive electrode (LiMn 2O4 material), a negative electrode (graphite material), an electrolyte and a diaphragm. When the power supply charges the battery, electrons on the positive electrode run to the negative electrode through an external circuit, lithium ions jump into electrolyte from the positive electrode, climb through a small bent hole on the diaphragm, swim to the negative electrode, and are combined with the electrons running in the morning. When the battery discharges, electrons on the negative electrode run to the positive electrode through an external circuit, lithium ions jump into electrolyte from the negative electrode, climb through a small bent hole on the diaphragm, swim to the positive electrode, and are combined with the electrons which run in the early period. Lithium ions first start from the positive electrode and reach the negative electrode through the electrolyte, and during the first charging and discharging of the battery, a passivation layer with solid electrolyte characteristics, namely a Solid Electrolyte Interface (SEI), is formed between the electrode and the liquid electrolyte. The SEI has double identities, is an electronic insulator and is also an excellent conductor of lithium ions, the film can protect the battery, avoid harmful reaction and lead the lithium ions to shuttle back and forth between an electrode and an electrolyte, the SEI is a key point for the performance of the lithium ion battery, and if the SEI is poor in performance, the battery has many problems. Once SEI begins to decline, the problem of piling up is followed up, like after many charges and discharges, lithium electrode deposit inhomogeneous and grow out the crystallization easily, and these lithium metal crystallization can move the structure to shelter from lithium ion, influence the removal of lithium ion, and then cause battery capacity loss, charge-discharge efficiency to reduce, or, along with the continuous increase of lithium metal crystallization, can pierce through the diaphragm, make positive, negative pole short circuit, finally lead to the battery to catch fire. In addition, the working environment temperature of the lithium ion battery is 0-40 ℃, when the environment temperature is lower than 0 ℃, capillary pores on the diaphragm, also commonly called as 'small holes', are reduced due to the principle of expansion with heat and contraction with cold, so that lithium ions are difficult to or cannot pass through the diaphragm, the lithium ions are easy to condense in the electrolyte and move slowly, the lithium ion battery cannot be normally charged and discharged, and the overall performance is reduced. Therefore, how to ensure normal charging and discharging of the lithium ion battery in a cold climate environment is also a technical problem to be solved urgently.

Therefore, for the lithium battery, the applicant proposes a technical scheme with a patent application number of 201910235529.4 and a name of "an ultrasonic intelligent temperature-increasing crystallization-preventing lithium battery" to the national intellectual property office in 2019, 03 and 27, and the scheme mainly comprises the lithium battery, an ultrasonic transducer, a temperature sensor, a control circuit board module, an ultrasonic generator, a metal shell and the like. According to the scheme, the ultrasonic transducer is arranged on the metal shell of the lithium battery, and the cavitation effect generated when the ultrasonic transducer works is utilized, so that the formation of lithium metal crystals in the lithium battery is reduced or relieved, the crystals are prevented from shielding or puncturing a diaphragm, and the service life of the lithium battery is prolonged; and under the cold climate environment, the cavitation effect of the ultrasonic wave can also be utilized, so that the lithium ions in the lithium battery can move in an accelerated manner, the temperature in the lithium battery is promoted to rise, and the problems of charging and discharging of the lithium battery under the cold climate environment are solved. Although the solution can solve the crystallization and the charging and discharging problems in the cold climate environment of the lithium battery to a great extent compared with the traditional lithium battery, the complexity and the volume of the battery structure are increased to a certain extent accompanying with the solution, and the ultrasonic wave is applied externally, so that the efficiency is not high, and the solution is not the optimal solution.
