Technical Field

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

Background

The lead-acid battery mainly comprises a battery shell, a positive plate, a negative plate, a partition plate, electrolyte and the like, wherein the partition plate is inserted between the positive plate and the negative plate so as to prevent the positive plate and the negative plate from being in mutual contact to cause short circuit, countless fine holes are densely distributed on the partition plate, so that the electrolyte can be ensured to pass through, the positive plate and the negative plate can be isolated from being in contact with each other, the reaction speed of the electrolyte can be controlled, and the battery can be protected. In the existing lead-acid battery, after the battery is used for a period of time, lead sulfate crystals are attached to the surfaces of the positive plate, the negative plate and the separator, and the lead sulfate crystals on the separator are increased continuously to block the electrolyte from passing through; the lead sulfate crystals coated on the surfaces of the positive and negative electrode plates increase, and the conductivity between the positive and negative electrode plates and the electrolyte is affected. Therefore, the lead sulfate crystals on the separator and the lead sulfate crystals on the positive and negative plates affect the storage performance and the charge/discharge performance of the lead-acid battery. Over time, lead-acid batteries can fail to store electricity and charge and discharge.

In addition, electrochemical polarization and concentration polarization exist in the charging and discharging process of the lead-acid storage battery, and large-current charging and discharging are mainly influenced by the concentration polarization. When the working temperature of the lead-acid storage battery is reduced to be lower than 0 ℃ for charging, the negative plate can generate serious concentration polarization at the initial charging stage, so that the charging acceptance of the battery is limited, and further, the charging and discharging of the battery are obviously reduced along with the reduction of the temperature. When the environmental temperature is reduced to below 0 ℃, the internal resistance is increased by about 15% when the temperature is reduced by 10 ℃, and the viscosity of the sulfuric acid solution is increased, so that the resistance of the sulfuric acid solution is increased, and the electrode polarization influence is aggravated. The battery capacity is significantly reduced. At present, a lead-acid storage battery is applied in a low-temperature environment, and a good battery temperature rise solution is not provided.

The lithium ion battery mainly comprises a positive electrode (LiMn 2O4 material), a negative electrode (graphite material), an electrolyte and a diaphragm sheet. 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 sheet, and 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 sheet, 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 times of charge and discharge or many fast charges, 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 and discharge efficiency to reduce, or, along with the continuous increase of lithium metal crystallization, can pierce through the diaphragm sheet, make positive and negative 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, also commonly called small holes, on the diaphragm sheet are reduced due to the principle of expansion with heat and contraction with cold, so that lithium ions are difficult to or cannot penetrate through the diaphragm sheet, the lithium ions are easy to condense in the electrolyte, the movement is slow, the lithium ion battery cannot be normally charged or 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.

In the application process of the existing-stage lead-acid storage battery and the existing lithium ion battery, when the problems respectively occur, the lead-acid storage battery generally adopts the steps of cutting a battery shell, taking a positive plate, a negative plate, a partition plate and the like out of the battery shell, and removing lead sulfate crystals attached to the positive plate, the negative plate and the partition plate by using a cleaning solution and a cleaning tool; after finishing, the positive plate, the negative plate and the partition plate are installed back to the battery shell, the cutting positions are sealed and welded, and new electrolyte is added into the battery to finish repairing. For lithium ion batteries, at present, there is no repairable means at all, and only the whole waste products are discarded.
