3D Cubic Structured Polymer Electrolyte with Face-Centered Cubic Aligned Non-Conductive Blocks

This technology forms a continuous ion-conductive matrix by combining the ion-conductive blocks of a block copolymer with an ionic liquid, and minimizes the tortuosity of ion conduction paths by aligning non-conductive blocks into a face-centered cubic (FCC) or O70 structure.

Conventional polymer electrolytes have faced limitations such as high tortuosity in ion conduction paths, low ionic conductivity due to structural disorder, and insufficient mechanical strength.

By incorporating an ionic liquid into a block copolymer composed of hydrophilic conductive blocks (such as sulfonated polystyrene) and hydrophobic non-conductive blocks (such as polymethylbutylene), this technology controls the nanostructure to ensure non-conductive domains are regularly aligned in an FCC or O70 cubic structure, providing a foundation for enhancing the maturity of secondary battery electrolyte technology.
