Abstract: Disclosed is a sulfide-containing solid electrolyte material with an organic coating, as well as densified pellets containing this solid electrolyte material, a solid electrolyte thereof, and a solid state battery containing the solid electrolyte. According to aspects of the disclosure, the coating comprising a compound of Chemical Formula (1) or Chemical Formula (2) is formed on the surface of a sulfide-containing solid electrolyte material, e.g., the organic coating may comprise a compound having a thiol with a long hydrophobic tail, such as 1-undecanethiol. The coating provides densification of sulfide-containing solid electrolyte materials, and facilitates the ionic and lithium atomic diffusion coefficient at sulfide grain boundaries during pressing, thus achieving the densification of sulfide solid state electrolyte.

Abstract: A locking mechanism is provided, including a locking body, a first connection member, a second connection member, a locking block rotatably connected to the locking body, a first locking member and a second locking member disposed on the locking block, a first matching portion formed on the first connection member and matching the first locking member, and a second matching portion formed on the second connection member and matching the second locking member. When the first matching portion and the second matching portion are respectively locked with the first locking member and the second locking member, the locking block is fixed with respect to the locking body; when the first matching portion is separated from the first locking member or the second matching portion is separated from the second locking member, the locking block rotates with respect to the locking body. The locking structure avoids unilateral locking and is convenient.

Abstract: A power conversion system for converting an input power to an output power, includes: a current limit circuit clamping an input current of the output power to be not exceeding an input current limit during a current clamping state; and a charge quantity regulation circuit converting the output power to a temporary storage power in a temporary storage capacitor during a charging mode, wherein the charge quantity regulation circuit converts the temporary storage power to generate the output power in collaboration with the current limit circuit during a discharging mode. When the input current reaches a current threshold, the charge quantity regulation circuit enters the discharging mode. During the discharging mode, the charge quantity regulation circuit regulates an output voltage of the output power to a target level, wherein the target level is lower than an input voltage of the input power.
