Porous structure for lithium metal electrodes with controlled full width at half maximum (FWHM) using a dual-porous architecture
This technology relates to a dual-porous structure in which a lithium-affinity polymer and a second porous structure with pores of controlled FWHM are disposed on a first porous structure.
Conventional lithium metal electrodes have faced limitations in ensuring battery safety and longevity due to uneven lithium deposition and dendrite growth.
By controlling lithium behavior in stages through a dual-porous structure, this technology can be applied to lithium metal batteries to suppress dendrite growth and enhance electrode stability.
Key Features:
- A porous structure for lithium metal electrodes comprising a first porous structure and a second porous structure positioned thereon
- A structure in which the second porous structure includes a lithium-affinity polymer, a 3D architecture, and pores with a FWHM of 0.01 to 1.0 micrometers
- Step of preparing a slurry by mixing and stirring a lithium-affinity polymer, a conductive material, and a solvent
- Step of forming a dual-porous structure via phase separation by immersing the slurry-coated substrate into a non-solvent bath
