Small-Molecule Polycyclic Aromatic Hydrocarbons
In article number 2400273, Jeng-Kuei Chang, Elise Yu-Tzu Li, Yu-Sheng Su, and co-workers present geometric variations of pyrene crystals during the electrochemical process in Li-ion batteries. The image illustrates the irreversible structural collapse caused by the vertical expansion of pyrene dimers, leading to the dissolution of pyrene into the electrolyte, a key factor affecting the long-term cycling stability of the anode material.
