Novel positive pole material drying device of power lithium battery

Abstract

The invention discloses a novel positive pole material drying device of a power lithium battery. The novel positive pole material drying device comprises a device body, microwave emitters and a dehumidifier, wherein a feeding hopper is arranged at the upper end of the device body and is used for adding a positive pole material to be dried into the device body; the right side wall of the device body is provided with a first discharge port and a second discharge port; the number of the microwave emitters is two, the two microwave emitters are arranged on the top wall and the bottom surface of the device body respectively, and the microwave emitters can emit microwaves to carry out microwave drying on the material in the device body; and the dehumidifier is further arranged in the device body, and the dehumidifier is used for dehumidifying the device body. According to the novel positive pole material drying device of the power lithium battery, the microwave emitters, a sieve plate and the dehumidifier are arranged, and the positive pole material is dried in a microwave drying mode, so that materials with different sizes can be separately dried by the sieve plate, the drying efficiency is greatly improved by arranging the dehumidifier, the drying speed is high, the drying period is short, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a novel positive electrode material drying device for power lithium batteries. Background technique [0002] Lithium batteries have the characteristics of high specific energy, low self-discharge, high working voltage, environmental friendliness and no memory effect. At present, lithium batteries have higher and higher requirements for cathode materials, especially the moisture contained in cathode materials has a great impact on lithium batteries. The moisture in cathode materials affects the manufacturing process of lithium batteries and also affects the service life of lithium batteries. [0003] However, the traditional lithium battery cathode material drying device uses hot air drying, which has the disadvantages of low efficiency and high energy consumption. Therefore, the present invention proposes a new type of positive electrode material drying device for power...
