Cellulose is the most abundant biopolymer on Earth and has long been used as a sustainable building block of conventional paper. Note that nanocellulose accounts for nearly 40% of wood’s weight and can be extracted using well-developed methods. Due to its appealing mechanical and electrochemical properties, including high specific modulus (∼100 GPa/(g/cm3)), excellent stability in most solvents, and stability over a wide electrochemical window, nanocellulose has been widely used as a separator, electrolyte, binder, and substrate material for energy storage. Additionally, nanocellulose-derived carbon materials have also drawn increasing scientific interest in sustainable energy storage due to their low-cost and raw-material abundance, high conductivity, and rational electrochemical performance. The inexpensive and environmentally friendly nature of nanocellulose and its derivatives as well as simple fabrication techniques make nanocellulose-based energy storage devices promising candidates for the future of “green” and renewable electronics. For nanocellulose-based energy storage, structure engineering and design play a vital role in achieving desired electrochemical properties and performances. Thus, it is important to identify suitable structure and design engineering strategies and to better understand their relationship.

面向高级能量存储设备的纳米纤维素:结构和电化学

纤维素是地球上最丰富的生物聚合物,长期以来一直被用作传统纸张的可持续构建基块。请注意,纳米纤维素约占木材重量的40%,可以使用发达的方法进行提取。由于其吸引人的机械和电化学性能,包括高比模量(〜100 GPa /(g / cm 3)),在大多数溶剂中的优异稳定性以及在宽阔的电化学窗口范围内的稳定性,纳米纤维素已被广泛用作隔膜,电解质,粘合剂和用于储能的基材。另外,由于纳米纤维素衍生的碳材料的低成本和原材料丰富,高电导率以及合理的电化学性能,它们在可持续能源存储方面也引起了越来越多的科学兴趣。纳米纤维素及其衍生物的廉价和环保特性以及简单的制造技术使基于纳米纤维素的储能设备成为“绿色”和可再生电子技术未来的有希望的候选者。对于基于纳米纤维素的能量存储,结构工程和设计在实现所需的电化学性能和性能方面起着至关重要的作用。
