Why is it important?
Manganese dioxide is a commonly used materials for pseudo-capacitors but its limited electrical conductivity is a major hurdle that impedes its excellent performance in capacity and rate handling performance. Reducing its electrical resistance will enable the feasibility of manganese dioxide for electrochemical energy storage.
Perspectives
The method reported in this paper is facile and efficient. It is expected to exert profound influence in the research field of lectrochemical energy storage.
