Recently, Wu Zhongshuai, researcher of the State Key Laboratory of Chemistry and Energy Application of Two-dimensional Materials, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, and his team have made progress in the research of hybrid electrochemical energy storage devices, and built a similar work with lithium-ion batteries.
Electrochemical energy storage devices represented by lithium-ion batteries and supercapacitors are widely used.
Researchers choose orthogonal Nb 2 O 5 (T-Nb 2 O 5 ) with intrinsic lithium ion intercalation pseudocapacitance properties as the negative electrode, and high nickel ternary lithium ion battery material LiNi 0.
2 5 2 5 0.
Dalian Institute of Chemical Technology has developed a new type of "double high" lithium-ion battery-supercapacitor hybrid energy storage device
