A team led by Professor Gan Lihua and Professor Liu Mingxian from the School of Chemical Science and Engineering at Tongji University specializes in researching high-efficiency energy storage materials for application in next-generation batteries. Recently, the team innovated by designing organic superstructure electrode materials through multiple hydrogen bond self-assembly. These materials exhibit a unique low bandgap conjugated planar structure along with an extended electron delocalization pathway, facilitating stable 15 e− NH4+ coordination through carbonyl/imino groups at exceptionally low activation energy. This groundbreaking development establishes new benchmarks for the capacity and cycle life of all-organic batteries, achieving an impressive 213 mAh g−1 with a remarkable 100,000 cycles.
