The invention provides a super capacitor cell encapsulation method, relating to the technical field of super capacitor manufacturing. Through the optimization and improvement of the liquid injection flow, the influence of factors possibly causing air expansion in the super capacitor is minimized in a mode of vacuum baking in combination with liquid pre-injection. The method effectively solves the problems of internal resistance increase, high capacity fading speed, serious self discharge, leakage current increase, short service life and the like of the super capacitor caused by air expansion, and improves the electrochemical performance of the super capacitor in whole.
