Solid Electrolyte for Secondary Batteries, Method for Preparing the Same, and Lithium Secondary Battery Including the Same

Safety-Enhanced Solid Electrolyte-Based Lithium Secondary Battery Technology

This technology relates to a solid electrolyte having high ionic conductivity and an increased lithium-ion transference number, and to a lithium secondary battery including the same.

Conventional liquid electrolytes have had low safety because of flammability and high reactivity, and they have also faced limitations in forming stable interfaces for suppressing lithium dendrites. This technology applies an electrochemically stable solid-electrolyte composition and production process to realize a more stable battery configuration.

As a result, it can improve electrolyte safety and lithium-ion transport efficiency, making it advantageous for high-energy-density lithium batteries and next-generation all-solid-state batteries.

Key Features:

• It uses a solid electrolyte having electrochemical stability and high ionic conductivity.
• It improves interfacial stability and output characteristics by securing an increased lithium-ion transference number.
• It contributes to improved battery safety by reducing the flammability and reactivity issues of liquid electrolytes.
