Abstract

The invention discloses a high-purity copper-based battery based on plant activated carbon and a preparation method thereof. The high-purity copper-based battery based on the plant activated carbon includes a high-purity copper mesh, a plant activated carbon filler, an electrolyte, a diaphragm, a negative electrode sheet, and a shell; the high-purity copper mesh is distributed with mesh openings;the plant activated carbon filler is mixed with the electrolyte and tightly filled in the mesh openings of the high-purity copper mesh as a positive electrode sheet; the diaphragm is disposed betweenthe negative electrode sheet and the positive electrode sheet; the end faces of the negative electrode sheet and the positive electrode sheet are provided with electrode ears; and the electrolyte is filled in the gaps among the negative electrode sheet, the positive electrode sheet and the diaphragm in the shell. The preparation method of the high-purity copper-based battery based on the plant activated carbon comprises the steps of preparation of the plant activated carbon filler, filler mixing, mesh filling and assembly. According to the invention, the high-purity copper mesh is filled withthe plant activated carbon, and a larger surface area of the activated carbon is used for capturing more ions, therefore, the battery power is increased, and the battery performance is improved; and the high-purity copper-based battery based on the plant activated carbon has the characteristics of low cost, environmental protection, high performance capacity, high conductivity, high rate, and canmeet various requirements of charge and discharge.

Description

technical field

[0001] The invention belongs to the technical field of electrochemical energy storage, and specifically relates to a high-purity copper-based plant-based activated carbon that is low in cost, environmentally friendly, high in capacity, high in conductivity, high in rate, and capable of meeting various requirements for charging and discharging. Batteries and methods of making them. Background technique

[0002] A battery is a device for energy conversion and storage. It consists of two electrochemically active electrodes with different components. The positive and negative electrodes are respectively immersed in the electrolyte that can provide media conduction. "A certain electromotive force is generated between them; when connected to an external carrier, it provides electrical energy by converting its internal chemical energy.

[0003] Regardless of whether it is a lithium-ion battery, a traditional alkaline battery, or the current environmentally friendly...
