The application provides a split type steam explosion equipment, and relates to the technical field of steam explosion equipment. The steam explosion equipment comprises a rack, a steam explosion tank is fixedly connected inside the rack, a lower piston sealing plate and an upper piston sealing plate are slidably connected inside the steam explosion tank, a lifting push rod is fixedly connected to the top surface of the upper piston sealing plate, a buffer mechanism is arranged inside the rack, a feeding mechanism is arranged outside the steam explosion tank, and a silencing mechanism is arranged outside the rack. The steam explosion tank, the buffer mechanism, the feeding mechanism and the silencing mechanism are arranged, the whole steam explosion machine is split into multiple independent components, the processing difficulty is greatly reduced, transportation and on-site installation are facilitated, and the maintenance cost is reduced. The buffer mechanism, the feeding mechanism and the silencing mechanism can significantly improve the operation stability and operation convenience of the equipment, effectively guarantee the sealing performance of the device, reduce the noise generated during equipment operation, and improve the use comfort and environmental protection of the equipment.

This invention provides a silicon-carbon composite material based on steam explosion, its preparation method, and its application, belonging to the field of silicon-carbon composite material technology. The preparation method includes the steps of preparing a precursor composite slurry, steam explosion, and simultaneous carbonization and activation. The steam explosion treatment step involves pumping the precursor composite slurry into a steam explosion reactor, introducing saturated steam, and maintaining pressure at 200-280℃ and 2.0-4.5MPa for 30-40 minutes. During the pressure maintenance, ultrasonic assistance is activated. After the pressure maintenance, a step-by-step depressurization is performed, i.e., 3-8 depressurizations are completed within 6-10 seconds, with each depressurization pressure being 10-30% of the previous one. After each depressurization, the pressure is held momentarily for 0.1-0.2 seconds, and finally completely depressurized to atmospheric pressure. After drying, the exploded product is obtained. The silicon-carbon composite material obtained by the method of this invention exhibits excellent cycle performance and rate performance when applied to batteries.
