1results about How to "No purification required" patented technology

The application belongs to the technical field of lithium-sulfur battery manufacturing, and particularly relates to a preparation device and a preparation method of high-purity ultrafine lithium sulfide electrolyte. The preparation device of high-purity ultrafine lithium sulfide electrolyte comprises a reaction furnace, a lithium microflow mechanism and a sulfur gasification mechanism are throughly arranged on the reaction furnace, and an ultrasonic generator is further arranged on the reaction furnace, and a tray is slidably arranged in the reaction furnace. The lithium microflow mechanism comprises a glove box and a smelting furnace which are throughly connected, a first mechanical valve is arranged at the communication part of the glove box and the smelting furnace, and a feeding pipe is further throughly arranged between the glove box and the smelting furnace. The smelting furnace is throughly connected with the reaction furnace through a microflow pipeline, and a microflow meter is arranged on the microflow pipeline. The sulfur gasification mechanism comprises a sulfur raw material bin and a tubular furnace which are throughly connected through a raw material pipeline, and the tubular furnace is throughly connected with the reaction furnace through an airflow pipeline. The application can continuously prepare lithium-sulfur electrolyte with high purity and low particle size without interruption, has the advantages of low cost and no other sulfide production, and is suitable for industrial production.
