A key development for LIBs is the establishment of their cathode and anode materials.
Because graphite materials have a high capacity and are cheap, they are the top choice for use as anode materials for LIBs.
This study adopted phenolic resins as the materials for producing hard carbon.
This is because B-2 was double coated with polymer materials.

Nuclear waste materials are nuclear ashes, which are the residues after burning the nuclear material in the nuclear reactor.
Alumina ceramics has high hardness and fusion point, it also has a good thermal stability and chemical stability, so it is a suitable candidate for the transmutation target matrix materials.
During the period of making it dry, rabble it all the time in order to mix the paraffin and powder materials completely.
