Problems solved by technology

[0003] However, lead-acid batteries have disadvantages, that is, short life and limited number of cycles. The main reason is that the lead grid of the positive plate cannot withstand the erosion of oxidation during charging and is broken, so it loses the function of supporting active materials and gathering current.
The lead particles, the active material of the negative plate, react with the dilute sulfuric acid to accumulate lead sulfate every time it is discharged, resulting in the “lead sulfate” of the white plate, forming a huge resistance, so that the battery cannot be charged and becomes invalid.

Abstract

The invention relates to the technical field of electrochemical energy storage equipment, and discloses an overlapped copper-acid storage battery. The overlapped copper-acid storage battery comprises a housing (1), an electrolyte (7), a negative electrode plate (5) and a partition plate (4); the electrolyte comprises a copper sulfate saturated aqueous solution; the current carrier of the negative electrode plate is a pure lead sheet or a copper sheet, wherein a metal layer resistant to dilute sulphuric acid is plated on the surface of the copper sheet; and a copper layer is plated on the surface of the current carrier of the negative electrode plate to be used as the negative electrode active substance. According to the copper-acid storage battery, copper is used to replace lead to be used as the negative electrode active substance; the mixed liquid of dilute sulphuric acid and copper sulfate is used as the electrolyte; the charging / discharging electrochemical reaction of the negative electrode plate only comprises the conversion of copper and the copper sulfate, so that the headache problem that the lead sulfate deposition in the negative electrode plate of a lead-acid storage battery is solved completely, and the service life of the copper-acid storage battery is greatly prolonged consequently.

Description

technical field [0001] The invention relates to the technical field of electrochemical energy storage equipment, in particular to a copper-acid battery derived from a lead-acid battery. Background technique [0002] Lead-acid batteries are currently the world's most mature technology, cheapest, stable performance, high voltage, high current, and most abundant raw materials. [0003] However, lead-acid batteries have disadvantages, that is, short life and limited number of cycles. The main reason is that the lead grid of the positive plate cannot withstand the erosion of oxidation during charging and is broken, so it loses the function of supporting active materials and gathering current. The lead particles, the active material of the negative plate, react with dilute sulfuric acid to accumulate lead sulfate every time it is discharged, resulting in the "lead sulfate" of the white plate, forming a huge resistance, so that the battery cannot be charged and fails.
