China’s first! A 1,000-ton-level high-performance carbon fiber demonstration line goes into operation, solving the challenge of strategic materials.

Recently, the completion and commissioning ceremony was successfully held for the first-phase 200-ton-per-year demonstration project—a thousand-ton-level high-performance carbon fiber project—under the E+PC general contracting model undertaken by China National Chemical Engineering Siding Company. This marks the commissioning of China’s first specialized production line for T1000-grade carbon fiber, breaking the country’s reliance on imported high-end carbon fiber and addressing a critical challenge in strategic materials.

Review: Cellulose-Based Materials for Environmentally Friendly Flexible Supercapacitors: Chemical Properties and Design Principles

In today’s global pursuit of green and low-carbon development, the demand for sustainable and environmentally friendly energy-storage technologies has become increasingly urgent. Against this backdrop, a nature-derived material—cellulose-based materials—are emerging as a promising new star in the field of flexible supercapacitors. Although flexible supercapacitors hold great promise thanks to their flexibility and lightweight characteristics, they still face significant bottlenecks, including insufficient energy density, poor environmental adaptability, and challenges in ensuring safety—a set of limitations that have hindered their large-scale adoption. Currently, the academic community lacks a comprehensive, authoritative review that systematically elucidates the intrinsic link between the “chemical properties” of cellulose materials and their “performance outcomes” in device applications. This is precisely the motivation behind our current study. To fill this gap, we have conducted a thorough and systematic review of cellulose and its derivatives. We not only summarize their physicochemical properties and assembly methods but also delve deeply into the chemical pathways through which they can be functionalized via oxidation, esterification, graft polymerization, and other techniques, revealing how cellulose transforms from an ordinary biomass material into a high-performance energy-storage component. More importantly, this review serves as a “application roadmap,” meticulously illustrating how various cellulose materials can be precisely integrated into key components of flexible supercapacitors—including electrodes, electrolytes, separators, and binders—and elucidating the underlying “structure-function” relationships. Finally, given that the large-scale application of cellulose-based flexible supercapacitors is still in its early stages, we proactively propose a holistic design framework that integrates “chemistry, performance, and sustainability.” This framework is not merely aimed at addressing the current limitations of these devices; rather, it seeks to chart a clear path forward for the next generation of truly green and high-performance flexible supercapacitors. We believe that by clarifying the logical chain—from “chemical structure” determining “device performance” to ultimately achieving “environmental sustainability”—we can powerfully propel flexible electronics toward a greener and more practical future.
