Microwave-enabled rapid,continuous,and substrate-free synthesis of few-layer graphdiyne nanosheets for enhanced potassium metal battery performance
摘要
Abstract
Graphdiyne(GDY)is a two-dimensional carbon allo-trope with exceptional physical and chemical properties that is gain-ing increasing attention.However,its efficient and scalable synthesis remains a significant challenge.We present a microwave-assisted ap-proach for its continuous,large-scale production which enables syn-thesis at a rate of 0.6 g/h,with a yield of up to 90%.The synthesized GDY nanosheets have an average diameter of 246 nm and a thick-ness of 4 nm.We used GDY as a stable coating for potassium(K)metal anodes(K@GDY),taking advantage of its unique molecular structure to provide favorable paths for K-ion transport.This modi-fication significantly inhibited dendrite formation and improved the cycling stability of K metal batteries.Full-cells with perylene-3,4,9,10-tetracarboxylic dianhydride(PTCDA)cathodes showed the clear superiority of the K@GDY anodes over bare K anodes in terms of performance,stability,and cycle life.The K@GDY maintained a stable voltage plateau and gave an excellent capacity retention after 600 cycles with nearly 100%Coulombic effi-ciency.This work not only provides a scalable and efficient way for GDY synthesis but also opens new possibilities for its use in energy storage and other advanced technologies.关键词
