    摘要: An all-solid-state battery system having a solid-state electrolyte composite is provided. The solid-state electrolyte composite includes a porous framework providing support and mechanical strength for the solid-state electrolyte composite and a plurality of ionic conductors filling voids of the porous framework for maximizing ionic conductance of the solid-state electrolyte composite. The porous framework may be made of ultra-high-molecular-weight polyethylene (UHMWPE) polymers and the plurality of ionic conductors may be made of poly(ethylene oxide)-LiN(SO2CF3)2 (PEO-LiTFSI) polymers. The all-solid-state battery system includes battery cells each including a cathode current collector, a cathode disposed beneath and connected to the cathode current collector, the solid-state electrolyte composite disposed beneath and connected to the cathode, an anode disposed beneath and connected to the solid-state electrolyte composite, and an anode current collector disposed beneath and connected to the anode.

    摘要: A composite material and methods for making a foldable material are provided. The composite material includes ultra-high molecular weight polyethylene (UHMWPE) and a hard coating material, a portion of the hard coating material being infiltrated into the UHMWPE. The UHMWPE has a highly porous structure of polyethylene and the hard coating material is in a liquid form. The UHMWPE can be formed as a layer on which another portion of the hard coating material is disposed. The layer of UHMWPE has a thickness smaller than 2 μm, a tensile strength greater than 500 MPa, and the composite has a thickness smaller than 5 μm, a tensile strength greater than 100 MPa. And the whole composite is crease free after more than 200,000 cycles of folding.
