Conductive particle for conducting ions and electrons of positive or negative electrode

A conductive particle for conducting ions and electrons of a positive or negative electrode;

• the positive or negative electrode being used in a solid-state or semi-solid battery;
• the conductive particle comprising:
• a ceramic particle serving to guiding lithium ion passing the positive or negative electrode to cause that the positive or negative electrode has uniformly distributed lithium ion channels;
• an amorphous carbon layer coated on an outer surface of the ceramic particle;
• the amorphous carbon layer having a specific conductivity to inhibit an over-expansion of a volume of the ceramic particle when the ceramic particle is filled with the lithium ions;
• a plurality of graphene sheet layers mixed within the amorphous carbon layer;
• each of the graphene sheet layers having a sheet structure;
• the graphene sheet layers forming a multilayer structure to wrap around an outer side of the ceramic particle;
• and
• a plurality of first carbon nanotubes (CNT) mixed within the amorphous carbon layer;
• the first carbon nanotube being dispersed in gaps between the graphene sheet layers and the ceramic particle and in gaps between different graphene sheet layers to be used as bridges between the graphene sheet layers and the ceramic particle.
