Abstract

The invention discloses a surface treatment device and method for a powder material for a battery, and relates to the field of powder surface treatment.The technical scheme includes that the surface treatment device comprises a drying box and two electric heating plates, a base is installed outside the drying box, a fixing cylinder is installed inside the drying box, and a spiral conveying rod is rotationally connected into the drying box; a feeding pipe is installed outside the drying box, an opening and closing mechanism is arranged outside the feeding pipe, and a smashing mechanism is arranged inside the feeding pipe; a plurality of outer ring guide plates are installed in the drying box, a plurality of inner ring guide plates are installed outside the fixing cylinder, a powder pumping machine is installed outside the drying box, a driving motor is started, the driving motor drives a spiral conveying rod to start to rotate, and the spiral conveying rod can circularly convey powder; the powder is conveyed to the position above the containing plate from the bottom of the drying box and then moves to the bottom of the drying box, in the process, the powder for the battery is fully dried, the subsequent quality of the battery is guaranteed, and surface treatment of the powder is achieved.

Description

technical field [0001] The present invention relates to the technical field of powder surface treatment, in particular to a device and method for surface treatment of powder materials for batteries. Background technique [0002] Powder is an aggregate composed of many small particles. Its common features are: it has many discontinuous surfaces, large specific surface area, and is composed of many small particles. [0003] The all-solid-state lithium battery that replaces the organic liquid electrolyte with a solid electrolyte is expected to completely solve the safety problem of the battery while solving the two key problems of low energy density and short service life of the traditional lithium-ion battery, which is in line with the future large-capacity battery. The development direction of new chemical energy storage technology. All solid-state lithium batteries, most of which use inorganic powder materials for each component, form a full battery through integrated tech...
