Lithium-philic polymer porous structure with pore size distribution controlled by non-solvent induced phase separation
This technology relates to a porous structure comprising a lithium-philic polymer and a three-dimensional structure with pores of a controlled full width at half maximum.
Conventional lithium metal electrodes suffer from issues such as non-uniform lithium deposition during charge and discharge cycles, leading to dendrite growth and degradation of the electrode structure.
By forming a lithium-philic polymer porous structure through non-solvent induced phase separation, this technology can be applied to lithium metal batteries to promote uniform lithium behavior and enhance electrode stability.
Key Features:
- A porous structure comprising a lithium-philic polymer and a three-dimensional structure with pores, where the full width at half maximum of the pore distribution is between 0.01 and 1.0 micrometers.
- Preparing a slurry by mixing and stirring a lithium-philic polymer, a conductive material, and a solvent.
- Applying the prepared slurry to a substrate at a specific thickness to form a porous structure.
- Immersing the slurry-coated substrate into a water bath containing a non-solvent to form the porous structure through phase separation.
