Qingdao Energy Institute has developed a three-dimensional germanium-carbyne material with ultra-high lithium storage performance

The Carbon-based Materials and Energy Application Research Group of Qingdao Institute of Bioenergy and Processes, Chinese Academy of Sciences has studied and prepared a three-dimensional porous material with a diamond-like framework composed of linear diacetylene bonds through sp ³ -hybridized germanium atoms—germanium-carbyne (Ge-CDY), and conducted in-depth research on its electronic structure, band gap and lithium storage capacity

Due to the change in the valence state of carbon atoms, carbon materials can be composed of a wide range of carbon skeleton structures, have good chemical and physical properties, and have been widely used in many fields such as catalysis, energy, and electronics

In order to obtain a three-dimensional sp-rich hybrid carbon material with stable structure, good electrical conductivity and good storage capacity for alkali metal atoms, Huang Changshui, a researcher at the Qingdao Institute of Bioenergy and Processes, Chinese Academy of Sciences, replaced graphodiyne (Nat Commun.
