Problems solved by technology

At the same time, the ultra-high electrical conductivity of titanium nitride (4000-55500S·cm -1 ) and mechanical stability make it a very promising electrode material for supercapacitors, but titanium nitride nanomaterials are easy to fall off from the surface of the electrode and are unstable.
[0005] In summary, there are still many defects in the existing electrode materials for supercapacitors, which cannot well meet the needs of practical applications. Therefore, it is necessary to improve the electrode materials for supercapacitors.
