Battery manufacturing process, battery treatment device, battery, and electric device

Abstract

A battery manufacturing process includes: acquiring a battery to be treated and injecting an electrolyte into the battery; and charging the battery before sodium in the battery is reduced at a negative electrode. In this application, the battery is charged before sodium in the battery is reduced at the negative electrode. In the process of charging the battery, water may receive electrons at the negative electrode and undergo a reduction reaction, producing hydrogen gas and hydroxide; or water may decompose in the electrolyte to generate hydrogen ions, and the hydrogen ions may receive electrons at the negative electrode to undergo a reduction reaction, producing hydrogen gas. In this way, water in the battery is removed. After removing water, sodium is reduced at the negative electrode to generate elemental sodium metal.
