Lithium Metal Electrode with Suppressed Dendrite Formation, Method for Preparing the Same, and Secondary Battery Including the Same

Dendrite-Suppressing Lithium Metal Electrode Technology

This technology relates to a lithium metal electrode technology that suppresses dendrite formation by using a metal-organic framework and lithium-philic metal ions.

Conventional lithium metal electrodes have continuously suffered from dendritic growth and low interfacial stability, causing lifespan reduction and safety issues. This technology coats a current collector with a metal-organic framework and organic linkers to provide lithium-ion guiding pathways and a uniform nucleation environment.

As a result, it can reduce dendrites and improve lithium-ion conductivity, thereby enhancing the safety, power density, and cycle life of high-capacity secondary batteries.

Key Features:

• It coats a current collector with a metal-organic framework and lithium-philic metal ions.
• It controls lithium nucleation and growth pathways through organic linkers.
• It simultaneously achieves suppression of dendrite formation and improvement of ion conductivity.
