Abstract
Abstract Extensive efforts are devoted to the design of new carbon materials with improved specific capacity for metal ion batteries (MIBs). One of the effective strategies for such material design is to change the structural unit. Recently, tetracene‐based nanoribbons have been synthesized (Chem. Eur. J. 2019 , 25 , 12074), which can be used as a basic building block to design a 3D porous TC 60 as demonstrated in this work. Based on first‐principles calculations, it is found that the 3D‐TC 60 shows high dynamical and thermal stability. Furthermore, the 3D‐TC 60 with its unique porosity and various adsorption sites can work as a high‐performance anode material for Li, Na, and K‐ion batteries with high specific capacity of 706, 706, 466 mAhg −1 ; low diffusion barrier of 0.25, 0.11, 0.08 eV; small volume change of 0.88, 1.96, 2.94%; and average voltage of 0.19, 0.24, 0.50 V, respectively. These intriguing findings suggest the promising prospect of tetracene based materials for battery technology.
