Abstract

Abstract: 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. Abstract : A novel aromatic imides‐derivatized material, benzophenolne‐3, 3′, 4, 4′‐tetracarboxylimide oligomer, is designed and synthesized for use as an anode material for lithium‐ion battery. It is demonstrated that 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 at low potential. First‐principles calculations are used to investigate its possible lithium storage mechanism incorporating with experimental verification.
