Description

Technical Field

[0001] This invention relates to the field of electrochemical application technology, and in particular to a regulating device and method for improving battery performance through a controllable magnetic field. Background Technology

[0002] With global population growth and accelerated industrialization, traditional fossil fuels are being rapidly depleted, leading to increasingly severe environmental pollution. Energy security and sustainable development have become a global focus. Under the "dual-carbon" strategy, developing new energy storage technologies with high energy density, low cost, and environmental friendliness aligns with national strategies, and zinc-air batteries have regained importance in this context. However, zinc-air batteries face challenges such as high catalyst costs, limited cycle life, and low current output, meaning large-scale application is still some time away. Adjusting the output current of zinc-air batteries is a common method for current improvements.

[0003] Currently, the adjustment of the output current of zinc-air batteries mainly relies on external circuitry. However, this method suffers from drawbacks such as increased size and cost, higher energy loss, increased system complexity, and reduced reliability, making it particularly unsuitable for portable and wearable devices sensitive to size and weight. Furthermore, existing attempts at indirect adjustment suffer from narrow adjustment range, slow response speed, poor stability, and low adjustment precision, failing to meet practical application requirements. Existing technologies have not yet developed any solutions for directly controlling the output current of zinc-air batteries using magnetic fields, nor have they recognized the potential of magnetic fields to regulate the internal electrochemical reaction processes and ion transport processes in the electrolyte. The core electrochemical reaction processes of zinc-air batteries involve electron transfer and ion migration. A magnetic field, as an external field that can be applied without contact, is easily and precisely controlled, and does not damage the battery structure, can theoretically influence the charge transport and reaction kinetics within the battery through Lorentz force, magnetohydrodynamic effects, etc., thereby achieving flexible adjustment of the output current. In summary, the purpose of this invention is to provide a device for improving the performance of zinc-air batteries by changing the magnetic field, offering advantages such as long battery life, low cost, rapid response, fast detection, and low background false detection rate.

The magnetic field adjustment unit 301 adjusts the speed of the conveyor belt 4 in the permanent magnet module 100 to increase or decrease the speed of cutting magnetic field lines. The direction of cutting magnetic field lines is changed by changing the direction of movement of the conveyor belt 4.

[0069] The current detection unit 302 is connected to the battery module 200. The current detection unit 302 collects the output current data of the battery module 200 in real time and feeds it back to the central control unit 303. The central control unit 303 generates an adjustment signal based on the comparison with the preset current threshold and sends a control signal to the magnetic field adjustment unit 301 to adjust the parameters of the adjustable magnetic field.

[0070] The core control principle of this invention is based on the targeted intervention of a magnetic field in key stages of the electrochemical reaction of battery module 2. Specifically, the core electrochemical reaction of battery module 2 involves the oxidation and dissolution of the zinc negative electrode (Zn + 2OH⁻ - 2e⁻ = Zn(OH)₂) and the oxygen reduction of the air positive electrode (O₂ + 2H₂O + 4e⁻ = 4OH⁻), accompanied by the migration of charged ions such as OH⁻ and Zn²⁺ in the electrolyte. This invention generates a controllable dynamic magnetic field by moving the permanent magnet module 100 via the conveyor belt 4. This magnetic field controls the reaction process through three main mechanisms:

[0071] The Lorentz force effect: A magnetic field exerts a Lorentz force on moving charged ions in an electrolyte.

[0072]

[0073] Where q is the ionic charge, v is the ionic velocity, B is the magnetic field strength, and θ is the angle between the ionic motion direction and the magnetic field direction, it can significantly change the migration rate of OH⁻ to the zinc anode and Zn²⁺ to the electrolyte, thereby regulating the reactant supply and product desorption efficiency on the electrode surface.

[0074] Magnetohydrodynamics effect: A dynamically adjustable magnetic field can drive the electrolyte to generate macroscopic or microscopic convection, breaking the static diffusion layer on the electrode surface, reducing concentration polarization, and solving the problem of current decay caused by limited ion transport during the discharge process of traditional battery modules.

[0075] Magnetocatalysis is an effect where a magnetic field can influence the spin state and transfer path of electrons on the electrode surface, reducing the activation energy of the zinc anode oxidation reaction while increasing the number of catalytic active sites and electron conduction efficiency of the air cathode catalyst, thus accelerating the oxygen reduction reaction kinetics.

[0076] Based on the above principle, when the actual current does not match the target value, the conveyor belt speed is adjusted by the above formula, and the magnetic field strength is changed to use the above mechanism to accelerate or decelerate the reaction and enhance or suppress ion migration, so as to ensure that the current is stable within the target range.

[0077] Example 2

[0078] Please see Figure 6 This invention provides a method for improving battery performance using an adjustable magnetic field. The method, employing the aforementioned adjustable magnetic field device, includes the following steps:

[0079] Step 1: Start the battery module 200 to enter working state;

[0080] Step 2: After the current value of the battery module 200 stabilizes, the target output current value of the battery module 200 is set through the central control unit 303 of the control module 300.

[0081] Step 3: The current detection unit 302 collects the actual output current data of the battery module 200 in real time and transmits the actual output current data to the central control unit 303;

[0082] Step 4: The central control unit 303 compares the actual output current data with the target output current value to determine if there is a deviation. If the actual output current value is equal to the target output current value, the adjustable magnetic field of the permanent magnet module 100 is maintained unchanged. If there is a deviation between the actual output current value and the target output current value, the next step is executed.

[0083] Step 5: The central control unit 303 generates a magnetic field adjustment signal based on the deviation between the actual output current value and the target output current value. The magnetic field adjustment signal includes at least one of the movement speed of the conveyor belt 4 and the movement direction of the conveyor belt 4.

[0084] Step 6: The magnetic field adjustment unit 301 receives the magnetic field adjustment signal and adjusts the speed and / or direction of the conveyor belt 4 to adjust the magnetic field parameters;

[0085] Step 7: Repeat steps 2-6 until the deviation between the actual output current data collected by the current detection unit 302 and the target output current value is within the preset error range.

[0086] More specifically, step 1 includes the following steps:

[0087] Step 1.1: Connect the electrolyte layer to the bottle containing the electrolyte. Pump out the electrolyte used in the previous operation of the zinc-air battery and simultaneously fill it with new electrolyte. Turn off the electrolyte pump. Use clamps to connect the anode of the battery module 200 to the positive terminal of the current detection unit 302, and the cathode of the battery module 200 to the negative terminal of the current detection unit 302, thereby forming a circuit to start the battery module 200.

[0088] More specifically, step 2 includes the following steps:

[0089] Step 2.1: After the battery module 200 is started, the actual output current of the battery module 200 will fluctuate in the initial period, which may cause the current detection unit 302 to make a misjudgment. Therefore, it is necessary to wait for the battery module 200 to run stably before detection. At the same time, during the stabilization process, the target output current value is set in preparation for adjustment.

[0090] More specifically, step 3 includes the following steps:

[0091] Step 3.1: The current detection unit 302 adopts a real-time acquisition mode to capture the dynamic changes of the current in a timely manner, so as to avoid missing the key current deviation due to the long acquisition interval and affecting the timeliness of adjustment. The acquired raw current signal needs to be processed for anti-interference.

[0092] More specifically, step 4 includes the following steps:

[0093] Step 4.1: After receiving the actual current data, the central control unit 303 compares it with the preset target output current value in real time to determine if there is a deviation. The deviation judgment is based on comprehensive analysis of multiple sets of continuously collected data to avoid misjudgments caused by accidental current fluctuations and ensure rigor. If multiple sets of actual current data are consistent with the target output current value, it is determined that the current magnetic field parameters are compatible with the battery response state, and the operating parameters of the permanent magnet module 100 remain unchanged. If there is a deviation between the actual current data and the target output current value, it is determined that the magnetic field adjustment process needs to be initiated, generating an adjustment signal to ensure that the current is promptly pulled back to the target range through magnetic field intervention.

[0094] More specifically, step 5 includes the following steps:

[0095] Step 5.1: After the magnetic field adjustment signal is generated, the central control unit 303 will verify it to check whether the magnetic field adjustment signal meets the safe operating range of the permanent magnet module 100, and to check the matching between the magnetic field adjustment signal and the current deviation to ensure that the adjustment direction is correct. After the verification is passed, the magnetic field adjustment signal is sent to the magnetic field adjustment unit 301.

[0096] More specifically, step 6 includes the following steps:

[0097] Step 6.1: The adjustment process must follow the principle of gradualism: whether it is to increase or decrease the speed of cutting magnetic field lines by adjusting the speed of conveyor belt 4, or to switch the direction of cutting magnetic field lines by changing the direction of movement of conveyor belt 4, it must be done at a steady rate to avoid sudden changes in magnetic field parameters causing drastic effects on the internal electrochemical reaction of battery module 200.

[0098] Step 6.2: When the actual output current is less than the target output current, the central control unit 303 controls the magnetic field adjustment unit 301 to increase the speed of the conveyor belt 4; when the actual output current is greater than the target output current, the central control unit 303 controls the magnetic field adjustment unit 301 to decrease the speed of the conveyor belt 4 or switch the direction of the conveyor belt 4.

[0099] Step 6.3: The specific mechanism by which the adjustable magnetic field acts on the battery module 200 is as follows: the Lorentz force generated by the adjustable magnetic field changes the migration rate of ions in the electrolyte, or the magnetohydrodynamic effect accelerates the oxidation and dissolution reaction of the zinc negative electrode and the oxygen reduction reaction kinetics of the air positive electrode, thereby controlling the magnitude of the output current.
