  "textContent": "A power supply battery and a power supply system for high-speed maglev trains. The power supply battery comprises: an electrolyte tank (10), a plurality of liquid flow pumps (20), and a plurality of aluminum-air battery reactors (30). The plurality of aluminum-air battery reactors (30) are sequentially connected in series. The electrolyte tank (10) comprises a plurality of elongate electrolyte grooves (101). One liquid flow pump (20) corresponds to one aluminum-air battery reactor (30) and one electrolyte groove (101). The power supply battery and the power supply system for high-speed maglev trains have the advantages of long-term storage without power loss, high energy density, high safety, abundant resources, low manufacturing costs and cleanliness and easy recovery by adopting aluminum-air batteries as the power supply of an on-board energy storage system of a high-speed maglev train. Moreover, a high voltage of the whole power supply battery can be ensured, self-discharge is reduced, high integration of the aluminum-air batteries is facilitated, the installation space is reduced, continuous work is realized, and energy can be continuously provided for maglev train loads.",
