A Novel High-Capacity Anode Material Derived from Aromatic Imides for Lithium-Ion Batteries.
A novel anode material for lithium-ion batteries derived from aromatic imides with multicarbonyl group conjugated with aromatic core structure is reported, benzophenolne-3,3',4,4'-tetracarboxylimide oligomer (BTO). It could deliver a reversible capacity of 829 mA h g-1 at 42 mA g-1 for 50 cycles with a stable discharge plateaus ranging from 0.05-0.19 V versus Li+ /Li. At higher rates of 420 and 840 mA g-1 , it can still exhibit excellent cycling stability with a capacity retention of 88% and 72% after 1000 cycles, delivering capacity of 559 and 224 mA h g-1 . In addition, a rational prediction of the maximum amount of lithium intercalation is proposed and explored its possible lithium storage mechanism.
