Title:
APPARATUS FOR ULTRASONIC WAVE-ASSISTED DRYING OF LITHIUM BATTERY ELECTROLYTE, AND DRYING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/082448
Kind Code:
A1
Abstract:
Disclosed in the present invention are an apparatus for ultrasonic wave-assisted drying of a lithium battery electrolyte, and a drying method, the apparatus comprising a temperature-controlled heating water bath, an ultrasonic wave system, and a vacuum pump. A heating rod and a thermocouple are provided in the temperature-controlled heating water bath. An ultrasonic wave oscillator is provided at the bottom of the temperature-controlled heating water bath, the ultrasonic wave oscillator being connected to an ultrasonic wave generator. The vacuum pump is connected to a drying bottle by means of a pipeline, the connection being designed using a flange interface. A switch valve and a vent valve are sequentially provided in the pipeline, a vacuum gauge is provided between the switch valve and the flange interface, and the vacuum pump is positioned in between the switch valve and the vent valve. In the present invention, by means of providing an apparatus for ultrasonic wave-enhanced vacuum drying of a lithium battery electrolyte, ultrasonic wave-enhanced vacuum drying technology is used to accelerate transmission of moisture from a lithium battery electrolyte to outside the system during a drying process. The method features a simple structure and convenient operation, and can markedly reduce the drying time of a lithium battery electrolyte and reduce the drying temperature for same.
