摘要

Graphite anodes remain the backbone of lithium-ion batteries, yet their utility is limited by sluggish lithium-ion transport kinetics under extreme conditions. Here we present a scalable method to synthesize graphitic aggregates using liquid-processable, polyacrylonitrile-based precursors, achieving a conformal graphite coating fully compatible with existing industrial workflows. This strategy effectively bypasses high-rate durability bottlenecks by tuning lithium–carbon interactions at the interface. Our findings establish liquid-processable polymer precursors as a high-throughput, manufacturable pathway towards the next generation of high-performance, sustainable energy storage.
