Abstract

The invention relates to the technical field of battery power supplies and in particular discloses a novel power supply with comprehensive performances of a supercapacitor and a zinc-silver battery. The power supply comprises electrolyte, a positive pole, a diaphragm and a negative pole, wherein the positive pole is isolated from the negative pole; the positive pole, the negative pole and the diaphragm are arranged in a battery shell, and the electrolyte is filled in the battery shell; the positive pole simultaneously has comprehensive capacities of a positive pole of the zinc-silver battery and a positive pole of the supercapacitor; the negative pole simultaneously has comprehensive capacities of a negative pole of the zinc-silver battery and a negative pole of the supercapacitor. According to the power supply, the advantages of high specific power of the supercapacitor and high energy of the zinc-silver battery are integrated, the problems that the battery polarization is sharply increased, the internal loss is increased, the energy storage efficiency is reduced, the voltage fluctuation is great and the like during high-current pulse discharge of the conventional zinc-silver battery are solved, the volume and weight are reduced, and the voltage accuracy and specific energy are improved.

Description

technical field [0001] The invention belongs to the technical field of battery power supplies, and in particular relates to a novel power supply with comprehensive performances of supercapacitors and zinc-silver batteries. Background technique [0002] The ever-growing aerospace energy requires the ability to discharge high-current pulses on the basis of conventional constant-power discharges, and the pulse working current can be dozens of times the battery capacity. [0003] If the current zinc-silver battery design technology is used, due to the large current pulse discharge, the battery polarization will increase sharply, the internal loss will increase, the energy storage efficiency will decrease, and the voltage will fluctuate greatly, etc., resulting in insufficient ability to drive these pulsating loads. Negative electrode 40% and volume increased by more than 30% can have sufficient high-current pulse discharge capability to ensure voltage accuracy requirements. Thi...
