▎ 摘　　要

NOVELTY - Preparation of flexible electrode comprises introducing carrier gas into dispersion liquid while performing centrifugal treatment, taking out dispersion liquid, spraying on substrate to remove dispersant in dispersion liquid, and solidifying to form a film. The dispersant in the dispersion comprises electrode active material and polymer matrix. The polymer matrix is dissolved in the dispersant. USE - The method is for preparation of flexible electrode used for all-solid-state battery (claimed). ADVANTAGE - Compared with direct mixing method for preparing flexible electrode, the preparation method by continuous centrifugal spraying way of preparing the electrode film, the film forming effect is good, keeping the mechanical property of the polymer matrix is excellent, and the electrochemical performance is obviously improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a flexible electrode; and (2) an all-solid-state battery comprising first electrode, second electrode and solid electrolyte. The first electrode and second electrode are arranged opposite to each other. The solid electrolyte is arranged between the first electrode and second electrode. The first electrode and/or the second electrode is the flexible electrode.
