Technical Field

The invention relates to the field of storage battery products, in particular to a separator or spacer mechanism applied between a positive plate and a negative plate of a storage battery.

Background

The lead-acid battery is mainly composed of positive plate, negative plate, partition board, container shell and electrolyte, the partition board is inserted between the positive plate and the negative plate to prevent the positive plate and the negative plate from contacting each other to cause short circuit, countless fine holes are densely distributed on the partition board, so that the electrolyte can be ensured to pass through, the positive plate and the negative plate can be isolated from contacting 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 surface of the partition board, and the passing of electrolyte is hindered along with the increase of the lead sulfate crystals, so that the storage performance and the charging and discharging performance of the lead-acid battery are influenced; over time, lead-acid batteries can fail to store electricity and charge and discharge.

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 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 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.

The number of the positive electrode plates 8, the negative electrode plates 9 and the ultrasonic isolation mechanisms 10 arranged in each cell compartment 7 may be arranged as required according to the size of the space of the cell compartment 7. The electric lid case 6 is also provided with a positive terminal 61 and a negative terminal 62. The positive terminal 61 is connected with all positive plates 8 in the battery in parallel, the negative terminal 62 is connected with all negative plates 9 in the battery in parallel, and the power supply wires 4 of the ultrasonic isolation mechanism 10 are connected in parallel and then arranged outside the electric cover shell 6 of the battery, and a pair of terminals 63 are installed for wiring of a user.

As shown in fig. 2, 4 or 6, the ultrasonic isolation mechanism according to the present invention includes an isolation workpiece 1, an ultrasonic vibration element 2; an inner chamber 3 for hermetically installing the ultrasonic vibration element 2 is arranged on the isolation workpiece 1, and the ultrasonic vibration element 2 is installed in the inner chamber 3 and extends out of the inner chamber 3 to an electric wire 4 arranged on the ultrasonic vibration element 2 outside the isolation workpiece 1, namely as shown in fig. 1. The isolating workpiece 1 can be designed into a shape corresponding to the shape of the applied battery according to the shape matching requirement.

The invention installs the ultrasonic vibration element 2 in the sealed inner chamber 3, which can effectively avoid the corrosion of the ultrasonic vibration element 2 by the battery liquid and ensure the service life of the ultrasonic vibration element 2. When the ultrasonic vibration element 2 is started to work after being electrified, the ultrasonic vibration element 2 generates ultrasonic high-frequency vibration to directly act on the isolation workpiece 1, so that the battery liquid generates an ultrasonic cavitation effect to continuously wash the surfaces of the isolation workpiece 1 and the positive and negative plates, and simultaneously, the substance molecules in the isolation workpiece 1 are accelerated to move, thereby effectively preventing the battery liquid from forming crystals on the isolation workpiece to influence the normal work of the isolation workpiece, and effectively ensuring the electric storage performance and the charge and discharge performance of the battery. Secondly, ultrasonic waves are utilized to generate high-frequency vibration, so that the internal molecules of the substance can move in an accelerated manner, the internal molecules of the battery liquid can move to increase the temperature, the purpose of assisting the temperature increase of the battery is achieved, and the charging and discharging efficiency of the battery is accelerated. Especially in extremely cold environment, can also solve the battery and charge and discharge the problem that the efficiency is low, unable normal work in winter.

On the basis of the above-described embodiment of the ultrasonic isolation mechanism 10, the present invention can develop roughly two different embodiments:

first, as shown in fig. 2 and 3 or fig. 4 and 5, the isolation workpiece 1 is a sheet-shaped partition, which is formed by laminating, fitting and packaging a left partition 11 and a right partition 12, and grooves 13 that relatively surround the inner chamber 3 are respectively provided on opposite side surfaces between the left partition 11 and the right partition 12. Meanwhile, concave wire grooves 14 through which the power supply wires 4 penetrate are further formed in opposite side faces of the left partition plate 11 and the right partition plate 12, so that the wires 4 can be conveniently routed and arranged. During assembly, the ultrasonic vibration element 2 is fixedly installed in the groove 13, the wires 4 are arranged along the concave wire slot 14, and then the left partition plate 11 and the right partition plate 12 are laminated, attached and packaged together to form the ultrasonic isolation mechanism 10.

This scheme can be divided into one scheme as shown in fig. 2 and 3 and another scheme as shown in fig. 4 and 5 according to the difference of the external shapes of the left and right separator sheets 11 and 12. As shown in fig. 2 and 3, an outer protrusion 15 is integrally formed on the outer side surfaces of the left and right separator sheets 11 and 12 at a position corresponding to the groove 13. The significance of this embodiment shown in fig. 2 and 3 is that the thickness of the spacer 1 can be made thinner to achieve an adaptive reduction in the overall cell volume and size. When the embodiment shown in fig. 2 and 3 is adopted, the positive electrode plate 8 and the negative electrode plate 9 are also correspondingly designed with the concave portions 20 which are correspondingly nested with the outer convex portions 15, so that they can be mutually nested and stacked together. The solution shown in fig. 4 and 5 is a solution with a more conventional thickness, and the solution is not optimally designed in terms of thickness.

Secondly, as shown in fig. 6 and 7, the isolation workpiece 1 is a sheet-shaped spacer, a ring of ring bodies 16 is further disposed on the spacer along four peripheries thereof, an inner chamber 3 is disposed in the ring body 16, and the ultrasonic vibration elements 2 are distributed and mounted in the inner chamber 3 along the ring body 16. This is a wrap-around type of solution, which performs ultrasonic treatment on an isolated workpiece 1 simultaneously by a plurality of ultrasonic vibration elements 2 arranged in a ring shape, and has good performance and effect.

The ultrasonic vibration element 2 is an ultrasonic transducer with the frequency of 1MHz or more or an ultrasonic vibration motor with the rotating speed of 1 ten thousand or more so as to obtain better ultrasonic cavitation effect and performance. The ultrasonic vibration element may be selected from a flat shape or a strip shape according to the portion of the battery to be used. In addition, in practical use, the present invention generally includes a controller or a host for controlling the operation of the ultrasonic vibration element, and the controller or the host is used to control the operation of the ultrasonic vibration element in the entire battery.
