New energy battery drying method

Abstract

The invention discloses a new energy battery drying method. The specific operation steps of the drying method are as follows: Step 1: Provide a new energy battery, open the box door and place the battery stably inside the drying box of the battery drying device, close the box door and the inside is sealed State; Step 2: The second three-way control valve is connected to the nitrogen pipe port, wherein the vacuum pump works to pre-vacuumize the drying box through the pumping port, and the second multi-way control valve part is using the valve port of the drying box and The valve port on one side of the second three-way control valve, the extracted air is discharged from the exhaust pipe of the second three-way control valve through the second control pipe, the vacuum degree in the drying box is -101KPa, the air pressure value is 100Pa, pre-vacuumize The processing time is 4-10 minutes; the present invention can fully remove the moisture in the new energy battery, and at the same time, the whole drying efficiency is high, which greatly shortens the manufacturing time of the new energy battery and improves the production efficiency of the whole new energy battery.

Description

technical field [0001] The invention relates to the field of new energy battery manufacturing, in particular to a new energy battery drying method. Background technique [0002] A battery refers to a cup, tank or other container or a part of a composite container that contains an electrolyte solution and a metal electrode to generate current, and is a device that can convert chemical energy into electrical energy; the use of the battery is not affected by the external climate and temperature, and its performance is stable Reliable, it plays a great role in all aspects of modern social life; with the rapid development of social economy, human demand for energy is also increasing, and the requirements are getting higher and higher. Traditional batteries can no longer meet people's requirements. The energy drive of mobile electronic devices, communication devices, and hybrid vehicles requires a large amount of mobile power sources. New energy batteries have been recognized and ...

Problems solved by technology

[0003] In the drying process of existing new energy batteries, they are generally dried directly under vacuum conditions, which is prone to incomplete water removal. In this way, the subsequent use of the battery will greatly affect the battery due to moisture out of control or coarse control. The decomposition of lithium salt in the electrolyte produces gas, which makes the battery swell and deteriorates the electrical performance; at the same time, the existing battery takes a long time to dry, which seriously affects the manufacturing efficiency of the battery
