AI Technical Summary

Technical Problem

Solid-state batteries suffer from impaired ion transport at the electrode-electrolyte interface, which affects charge/discharge rate, rate performance, and cycle life.

Method used

An adhesive layer composed of a two-dimensional material modified with negatively charged groups, a framework material, and a solid electrolyte is disposed on the side of the positive and negative electrode active material layers away from the current collector, forming a porous structure to accelerate ion transport and reduce impedance.

Benefits of technology

It improves the charge/discharge rate, rate performance, and cycle life of solid-state batteries. Through the synergistic effect of two-dimensional materials modified with negatively charged groups and framework materials, it provides lithium-ion transport channels and reduces polarization and ion impedance.

Abstract

This application discloses a solid-state battery and an electrical device, relating to the field of battery technology. The application provides a solid-state battery including a positive electrode, a negative electrode, and a solid electrolyte membrane. The positive electrode includes a positive current collector, a positive active material layer disposed on at least one surface of the positive current collector, and an adhesive layer disposed on the side of the positive active material layer away from the positive current collector. The negative electrode includes a negative current collector, a negative active material layer disposed on at least one surface of the negative current collector, and an adhesive layer disposed on the side of the negative active material layer away from the negative current collector. The adhesive layer includes a two-dimensional material modified with negatively charged groups, a framework material, a solid electrolyte, and a thermoplastic / thermosetting adhesive. The adhesive layer of this application, with its specific structure and material, is disposed on the side of the positive and negative active material layers away from the current collector, which improves both interfacial adhesion and rate performance and cycle life.
