Abstract

The invention discloses a full-sedimentary type lead acid liquid current battery energy storing device. The device comprises a liquid storing tank, a circulating pump, a flowmeter, an infusion tube, a reactor and an alternating current-direct current converter, wherein a guide wire, a battery lead plate, and other accessory devices are arranged on the reactor; an electrolyte in the liquid storing tank flows into the reactor under the function of the circulating pump and flows back to the liquid storage tank after the electrolyte is subjected to a redox reaction. According to the device, during charging, Pb ions in the electrolyte are subjected to a redox reaction resulting in the sedimentation of PbO2 on a positive plate and the sedimentation of Pb on a negative plate while during discharging, the sediments, namely the PbO2 on the positive plate and the Pb on the negative plate, are subject to the redox reaction so as to generate Pb ions for dissolving in the electrolyte, wherein during the charging and discharging processes, the magnitude of the electrolyte current is regulated through the flowmeter according to the differences in the aspects of charging and discharging current, the size of voltage or the number of the batter lead plate in the reactor.
