Inside Front Cover: Aromatic Carbonyl Derivative Polymers as High‐Performance Li‐Ion Storage Materials (Adv. Mater. 12/2007)

Molecular simulation of a PTCDA sulfide polymer crystal, in which a layered structure can be clearly observed. As reported on p. 1616 by Taolei Sun, Jutang Sun, and co‐workers, this is a new class of promising organic positive‐electrode materials for Li‐ion batteries. The excellent electrochemical performance of these materials, which is comparable or even superior to conventional inorganic materials, as well as their high safety, environmental friendliness, molecular design flexibility and diversity, and low cost, endow them with broad application and market potential.
