  • Publication number: 20230309196
    Abstract: The present invention provides a heating tray for a vacuum hopper precharger, wherein a heating part is configured in a tray having a secondary battery mounted thereon to allow heat generated from the heating part to be circulated inside a vacuum hopper precharger and to be transferred to the entire secondary battery so that the activity of an electrolyte inside the secondary battery is improved, and according thereto, a large amount of residual gas and impurities can be discharged so as to increase purity of the secondary battery. Particularly, the secondary battery can be fully charged with an electrolyte inside the vacuum hopper precharger, thereby improving productivity compared to a conventional configuration in which a secondary battery is charged with an electrolyte at 60% to 70% inside a vacuum hopper precharger and then charged with a remaining charge amount in another process so as to be fully charged.
