The invention discloses a device and a method for recycling gallium through activation and electrodeposition of a steel wool cathode. The device comprises a temperature control tank, a wire, a power supply, an electrolytic tank, a thermocouple, an anode, an electrolyte, a cathode and a temperature control medium, wherein the electrolytic tank is arranged in the temperature control tank, the temperature control tank is filled with a temperature control medium, the electrolytic tank is filled with electrolyte, the thermocouple, the anode and the cathode are arranged in the electrolyte, and the anode and the cathode are connected with a power supply through wires; and the cathode is a steel wool cathode. The steel wool cathode has a larger specific surface area, the mass transfer process in the electrodeposition process can be enhanced, and higher current efficiency and lower energy consumption are achieved when the steel wool cathode is adopted for recycling gallium in an electrodeposition mode. The gallium has
