▎ 摘　　要

NOVELTY - The device has a reaction device (1) connected with a centrifugal device (2) that is connected between a filtering device (3) and a drying device (5). An ultrasonic vibration device (4) is connected between the filtering device and the drying device. The filtering device is connected with a calcining device that is provided with a quartz tube type furnace body (61). An inner cavity of the quartz tube type furnace body is installed with a calcined groove (62). A lower end of the quartz tube type furnace body is provided with a supporting leg (610). USE - Lithium battery cathode material based graphene silicon preparing device. ADVANTAGE - The device is capable of forming four lithium-silicon (Li-Si) crystal phase structures, having a simple device operation, satisfying a requirement of producing graphene cathode material, improving performance and suiting for an industrial production in an effective manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium battery cathode material based graphene silicon preparing method. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a lithium battery cathode material based graphene silicon preparation device.
