Abstract

The invention provides a self-adsorbable flexible battery and a preparation method thereof. Cyclodextrin is grafted as a main body to a gel electrolyte polymer monomer to form a polymer monomer matrix carrying main molecules; The monomer matrix is ​​in-situ polymerized with the ungrafted gel electrolyte polymer monomer to generate a gel electrolyte incorporating host molecules; adamantane or ferrocene is grafted as a guest to the binder polymer monomer The polymer monomer matrix carrying the guest molecules is formed on the polymer monomer matrix; the prepared polymer monomer matrix carrying the guest molecules is polymerized with the ungrafted binder polymer monomer to generate a binder incorporating the guest molecules. ; Add the binder doped with guest molecules into the positive and negative electrodes, and encapsulate it with the gel electrolyte doped with host molecules to form a self-adsorbing sandwich flexible battery. Compared with the existing flexible batteries, the flexibility is improved while extending the The service life of the battery makes up for the shortcomings of the existing flexible battery technology.
