US 2026/0302433 A1 · METAL-AIR BATTERY, METAL-AIR-BATTERY SYSTEM, AND OPERATION METHOD OF THE METAL-AIR BATTERY SYSTEM

Abstract

A metal-air battery includes a unit battery cell and a weight sensor. The unit battery cell, which includes anolyte, a supporter, an anode being suspended from the supporter, and a cathode, is configured to generate electricity by using an oxygen reduction reaction in the cathode and an oxidation reaction of the anode. The weight sensor is configured to determine a weight of the anode of the unit battery cell. A metal-air battery system includes a metal-air battery and a controller configured to generate, based on a result of sensing by the weight sensor, a maintenance signal for the anode.
