Low temperature, atmospheric pressure for synthesis of a new carbon Ene-yne and application in Li storage

Highly conductive 2D Carbon Network was synthesized by conjugating alkadiynes with vinyl groups through solvent-phase preparation. Small band gap of 0.05 eV was predicted for this 2DCN, which lead to conductivity of 1.4×10−2 S/m, close to that of normal inorganic semiconductor. The assembled 2DCN-based Li-ion batteries exhibited excellent electrochemical performance, including high specific capacities, outstanding rate performances, and long cyclic lives.225
