  • Apparatus for enhancing electrolyte wetting in rechargeable battery and electrolyte wetting enhancing method using the same
    Patent number: 10862099
    Abstract: An apparatus for enhancing electrolyte wetting in a rechargeable battery, which can improve an electrolyte wetting dispersion and enhancing electrolyte wetting in the rechargeable battery by vacuating gases trapped in an electrode assembly by injecting an electrolyte into the electrode assembly and pushing the rechargeable battery, and an electrolyte wetting enhancing method utilizing the same. The electrolyte wetting enhancing apparatus includes a chamber having an internal space; a battery fixing unit fixed in the internal space of the chamber and including a plurality of rechargeable batteries mounted therein; and a pushing member pushing opposite side surfaces of the plurality of rechargeable batteries. The pushing member pushes the plurality of rechargeable batteries to enhance electrolyte wetting into an electrode assembly including the plurality of rechargeable batteries into which the electrolyte is injected.
