Abstract

The invention discloses a drying device for lithium ion battery negative electrode material production. The drying device comprises a bottom plate, a stirring box and a condensation box, wherein the stirring box and the condensation box are fixedly arranged above the bottom plate; a stirring shaft is rotationally arranged on the inner wall of the stirring box; a plurality of stirring devices are fixedly arranged on the stirring shaft; two drying devices are arranged above the stirring box; and each stirring device comprises a connecting block fixedly arranged on the stirring shaft. In the useprocess, through the arrangement of the stirring box, the stirring in the drying process is convenient; the drying efficiency of the device can be favorably improved; through the arrangement of the condensation box, the water vapor in the drying process can be conveniently liquefied in time; the drying efficiency of the device is further improved; through controlling the electrification of an electromagnet, the electromagnet is driven to move along a slide rod; and meanwhile, a spring is compressed.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery production, in particular to a drying device for production of lithium-ion battery negative electrode materials. Background technique [0002] Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge. [0003] In the production process of lithium-ion batteries, the negative electrode materials need to be dried. The existing drying devices for the production of lithium-ion battery negative electrode materials do not process the water vapor in t...
