ALL-SOLID-STATE PVB-BASED ION TRANSPORT MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF

Title:

ALL-SOLID-STATE PVB-BASED ION TRANSPORT MATERIAL, PREPARATION METHOD THEREFOR AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2021/119920

Kind Code:

A1

Abstract:

The present application relates to the technical field of ion transport materials, and particularly to an all-solid-state PVB-based ion transport material, a preparation method therefor and the use thereof. With single-layer graphene, single-wall carbon nanotubes or silver nanowires as a nano-powder, by controlling the content of a Lewis base containing an alkali metal in a conductive slurry and the ratio of the Lewis base to the nano-powder, the present application provides a high-conductivity ion transport material. In addition, the ion transport material is a solid material, and is applied to an electrochromic glue-laminated glass as an ion transport layer. The electrochromic glue-laminated glass is not only convenient to package, so as to solve the problem of difficult packaging of an electrochromic device, but also has a fast discoloration speed; in addition, the difference between the light transmissivity of the glass after being energized and stabilized and the light transmissivity when same is deenergized is greater than or equal to 45%, and the electrochromic effect is good. By means of the ultrasonic dispersion of a mixture of a dispersant, a solvent and the nano-powder using an ultrasonic cell mill with the dispersion time being controlled, the performance of the formed conductive slurry can be ensured and failure is prevented.
