    摘要： Methods for forming battery cells include providing a porous polymeric membrane (PPM), imbibing the PPM with a plasticizing solution comprising plasticizers and lithium salts to form a solid gel electrolyte film, and disposing the solid gel electrolyte film between an anode and a cathode. The PPM can be provided as a coating on the anode or the cathode. The plasticizers can be triethylene glycol dimethyl ether (triglyme), tetraethylene glycol dimethyl ether, and triethyl phosphate. The salts can be LiBF4, LiClO4, LiPF6, LiAsF6, LiTf, LiFSI, LiTFSI, and LIBOB. The plasticizer solution can be 17.5 wt. % to 27.5 wt. % LiTFSI and 72.5 wt. % to 82.5 wt. % triglyme. The plasticizer solution can be 56 wt. % to 66 wt. % LiTFSI and 33.5 wt. % to 43.5 wt. % triglyme. The plasticizer solution can be 16 wt. % to 26 wt. % LiTFSI, 9 wt. % to 19 wt. % triglyme, and 55 wt. % to 75 wt. % triethyl phosphate.

    摘要： A system and method for personalization of adjustable features of a vehicle. The system includes a processor and an actuator. The processor detectors key points of a person from a two-dimensional image and predicts a pose of the person. The processor translates a respective position of the key points from a two-dimensional coordinate system to a three-dimensional coordinate system based in part on the pose and measurements of distances between the key points. The processor determines a baseline configuration of an adjustable feature of the vehicle based in part on measurements between the key points in the three-dimensional coordinate system. The processor causes an actuator to adjust the adjustable feature to conform to the baseline configuration.

    摘要： The present disclosure relates to solid-state batteries and methods for forming solid-state batteries. The method includes contacting a polymeric precursor and an assembled battery including two or more electrodes defining a space therebetween, where the polymeric precursor fills the space defined between the two or more electrodes and any voids between the solid-state electroactive particles of each electrode; and reacting the polymeric precursor to form a polymeric gel electrolyte that forms a solid-state electrolyte layer in the space between the two or more electrodes and fills the voids between the solid-state electroactive particles of the electrodes. In other instances the method includes disposing the polymeric precursor on exposed surfaces of an electrode and reacting the polymeric precursor to form the solid-state electrolyte. In still other instances, the method includes disposing the polymeric precursor on a releasable film and reacting the polymeric precursor to form the free-standing electrolyte layer.
