Problems solved by technology

[0004] But on the other hand, the performance of only using carbon nanomaterials as electrode materials for supercapacitors is not very good, such as low charge and discharge efficiency, low specific capacitance, serious self-discharge phenomenon and easy agglomeration, etc.
[0005] At the same time, the energy density and power density of the currently reported porous carbon materials usually decay rapidly under high rate conditions, and it is difficult to meet the urgent needs of high energy / high power density for supercapacitors such as electric vehicles.
[0006] In recent years, due to their many excellent properties, titanium and its compounds have very important application value and broad application prospects in the fields of aviation, aerospace, vehicle engineering, biomedical engineering, etc., but so far, its application in supercapacitors There are few reports and scientific research
