摘要

Organic polysilazane (PSZ) and polyacrylonitrile (PAN) form a molecular interpenetrating network

yielding a polymer-derived SiCNO/C hybrid anode with high capacity

excellent cycling stability

and robust structure.

Abstract

Silicon-based anodes are promising candidates for next-generation lithium-ion owing to their high theoretical specific capacity. However

their practical application is limited by their severe volume expansion and poor electronic conductivity during cycling

which results in rapid capacity fading. To address these challenges

a novel polymer-derived ceramic (PDC) precursor

PSZ/PAN

was designed and synthesized by integrating polysilazane (PSZ) with polyacrylonitrile (PAN). The synthesis involved an initial free-radical polymerization of PSZ to form a crosslinked network

followed by

in situ

introduction and polymerization of acrylonitrile

yielding a PSZ/PAN hybrid with an interpenetrating network structure at the molecular level. Upon pyrolysis

the resulting SiCNO/C hybrid anode exhibited a high reversible specific capacity of 1050.1 mAh·g

–1

at 500 mA·g

–1

and excellent cycling stability

retaining 73.2% of its initial capacity after 600 cycles. This molecular-level interpenetrating design of polymer-derived ceramics provides a promising strategy for the development of high-performance anode materials for lithium-ion batteries.
