Abstract: Batteries include a current collector, a cathode, an interlayer disposed on the cathode, a solid-state electrolyte disposed on the interlayer, and a lithium anode disposed on the solid-state electrolyte. In aspects, the interlayer includes a lithium salt and a sulfone compound within a polymeric matrix. In aspects, the interlayer includes a lithium salt and a sulfone compound. In aspects, methods of forming a battery comprise disposing a precursor solution comprising a lithium salt, a sulfone compound, and a monomer on a first major surface of a cathode. Methods can further include curing the precursor solution to form an interlayer including the lithium salt and the sulfone compound within a polymeric matrix. In aspects, methods can include disposing a lithium salt and a sulfone compound on a first major surface of a cathode. Methods further include disposing a solid-state electrolyte over the first major surface of the cathode.

Abstract: A touch device usable for a hair dressing apparatus is disclosed. The touch device includes a touch sensing shell, an FPC (Flexible Printed Circuit) board and a PCB (Printed Circuit Board), wherein the touch sensing shell is mounted on the surface of the hairdressing apparatus. The FPC board is attached to the touch sensing shell and mounted between the touch sensing shell and the hairdressing apparatus. The PCB is connected with the FPC circuit board by use of a lead and mounted inside the hairdressing apparatus. The touch sensing shell is capable of sensing actions provided by the fingers of a user and preventing the FPC board from having direct contact with the user, A touch sensing region and a functional control unit are arranged on the FPC board and connected with a central processing unit.
