Skyline share | The silicon-carbon cathode material prepared by "a high temperature pyrolysis method

The release date:2020-03-02 Source:Original viewed:78

  High temperature pyrolysis usually uses polymer as carbon source,nano-silicon,silicon oxide,etc.as silicon source,using"silicon-carbon anode special coating equipment"developed by Hunan Skyline Smart&Material Technology Co,Ltd. under inert atmosphere Amorphous carbon-coated silicon materials produced by high-temperature pyrolysis of polymers to obtain carbon-coated silicon-structured silicon-carbon active materials are also common methods for the preparation of silicon-carbon composite materials.The amorphous carbon void structure produced by high-temperature pyrolysis of polymers is more developed,which can better inhibit the volume change of silicon-based materials,and its coating on the outside of silicon materials can act as a buffer. An anode active material of silicon/carbon/carbon nanotube ternary composite was prepared by pyrolyzing bitumen,nano-silicon,and specially treated carbon nanotubes.The initial discharge specific capacity can reach 1077mAh/g,and the reversible capacity after 20 weeks of cycling can still up to 703mAh/g.
