Abstract: The present disclosure relates to a care monitoring device and system. The care monitoring device includes an upper conductive assembly, a lower conductive assembly, an insulating assembly arranged between the upper conductive assembly and the lower conductive assembly, and a controller. The insulating assembly is provided with a hollow area. When a human body applies pressure to the upper conductive assembly, the upper conductive assembly and the lower conductive assembly are electrically connected through the hollow area in the insulating assembly, and the controller is configured to convert an electrical signal generated by the electrical connection into a pressure early warning signal.

Abstract: The invention relates to a mono-nuclei cationized magnesium salt, a preparation method and applications thereof. The mono-nuclei cationized magnesium salt has a chemical formula of MgRnMX4-mYm, wherein R is a non-aqueous solvent molecule, M includes Al3+ and/or B3+, X and Y respectively include halide ion and halogenoid ion, n is any one integer selected in the range of 0˜6, and m is any one integer selected in the range of 0-4. The mono-nuclei cationized magnesium salt provided by the invention has a simple structure and excellent electrochemical properties, and the preparation method thereof features low cost, integrated synthesis, accessible raw materials, simple preparation process, and simple scaled production.

Abstract: The invention provides a nitrogen-doped graphene coated nano sulfur positive electrode composite material, a preparation method, and an application thereof. The composite material includes: an effective three-dimensional conductive network formed by overlapping of nitrogen-doped graphenes, and nano sulfur particles coated by nitrogen doped graphene layers evenly. The preparation method includes: dispersing nitrogen-doped graphenes in a liquid-phase reaction system including at least sulfur source and acid, and depositing nano sulfur particles by an in-situ chemical reaction of the sulfur source and the acid, thereby preparing the positive electrode composite material. The positive electrode composite material of the invention has a high conductivity, a high sulfur utilization rate, and a high rate, thereby restraining the dissolution and shuttle effect in the lithium sulfur batteries, and enhancing the cyclic performance of the batteries.
