Alkynyl Boosted High-Performance Lithium Storage and Mechanism in Covalent Phenanthroline Framework

Yingnan Cao et al.

Summary: To address the poor conductivity of pristine bulk covalent organic materials, researchers synthesized a nanosized alkynyl-linked covalent phenanthroline framework (Alkynyl-CPF) for lithium-ion batteries. By improving intrinsic charge conductivity and insolubility, the Alkynyl-CPF electrode demonstrated superior cyclic performance and rate properties due to its low HOMO-LUMO energy gap and high degree of electron conjugation. Investigations into the energy-storage mechanism of C equivalent to C units and phenanthroline groups further provide insights for the design and mechanism investigation of covalent organic materials in electrochemical energy storage.
