Abstract
Description
Technical Field
[0001] This invention relates to the fields of aqueous energy storage batteries, household safety power supplies, and new energy storage technologies, and particularly to a non-corrosive, non-volatile, rechargeable, and maintenance-free sodium ion aqueous solution immersion energy storage battery. Background Technology
[0002] Traditional lead-acid batteries use concentrated sulfuric acid electrolyte, which has drawbacks such as strong corrosivity, easy volatilization of acid mist, environmental pollution, easy sulfation and degradation of the plates, and the need for frequent water replenishment and maintenance. Lithium batteries have problems such as flammability, explosiveness, high cost, and poor safety, making them unsuitable for indoor home energy storage. Existing aqueous batteries generally have shortcomings such as poor stability, easy evaporation, easy deterioration, and short cycle life, failing to meet the needs of safe, long-lasting, and maintenance-free home energy storage. Summary of the Invention
[0003] This invention comprises a single electrode plate, a bipolar plate, a chlorine- and fluorine-free sodium ion aqueous solution electrolyte, and an insulating shell. The electrode plates are made of corrosion-resistant conductive materials, and the electrolyte is a neutral chlorine- and fluorine-free sodium ion aqueous solution. During charging, sodium ions are deintercalated from the electrode and returned to the aqueous solution; during discharging, sodium ions are intercalated from the aqueous solution into the electrode, and the output current supplies power. The charging voltage is controlled within 1.2V, and there is no water electrolysis, no gas generation, no explosion, and no reduction in water volume. It adopts an immersion-type structure; the device starts working upon insertion of the electrode plate and stops immediately upon removal, with zero self-discharge. It supports both charging cycle and water-replacement-free modes. Waste liquid can be used for bathing, foot baths, watering plants, and diluting seasonings, achieving full-chain recycling.
[0004] Specific implementation method: Install the positive and negative plates at intervals in the insulating shell, inject a chlorine-free and fluorine-free sodium ion aqueous solution, and output electrical energy after the plates are completely immersed; connect the appropriate power supply when charging, and control the voltage within 1.2V; after the electricity is used up, pour out the old liquid for domestic use, and replace it with new liquid to continue generating electricity.
[0005] Attached image description: Figure 1 Figure 1 shows a simplified diagram of the structure and charging / discharging principle of a non-corrosive sodium ion aqueous solution-immersed energy storage battery. The battery mainly consists of an insulating shell, positive and negative electrode plates, electrode leads, and a sodium ion aqueous solution electrolyte. The positive and negative electrode plates are immersed in the sodium ion aqueous solution electrolyte, and the electrode leads extend from the top of the shell. During charging and discharging, sodium ions (Na⁺) reversibly migrate between the electrodes and the electrolyte: during charging, sodium ions are deintercalated from the electrodes and return to the aqueous solution; during discharging, sodium ions are intercalated from the aqueous solution into the electrodes and output electrical energy. The battery charging voltage is controlled at ≤1.2V to ensure no water electrolysis and no gas production, achieving safe and stable operation.
