【摘要】 纳米纤维素作为一种拥有良好生物相容性和可降解性的天然材料,拥有独特的结构和优异的机械性能,已经广泛应用于锂离子电池(LIBs)电化学储能系统的构建,并取得了显著的进展。本论文以先进储能设备LIBs和绿色材料纳米纤维素的应用为背景,概述了纤维素纳米纤维(CNF)、纤维素纳米晶体(CNC)和细菌纤维素(BC)的制备和改性方法,并对纳米纤维素在LIBs领域的应用研究进行综述。主要分为3个方面:1)纳米纤维素基柔性LIBs电极;2)纳米纤维素衍生的炭材料作电极;3)纳米纤维素衍生的电池隔膜。最后,分析了该领域的一些问题,并进行了总结和展望。更多还原

【Abstract】 As a natural material with good biocompatibility and biodegradability, nano-cellulose has unique structure and excellent mechanical properties. It has been widely used in the construction of electrochemical energy storage system of lithium-ion batteries(LIBs), and has made significant progress. This thesis provided an overview of the preparation and modification methods of cellulose nanofibrils(CNF), cellulose nanocrystals(CNC) and bacterial cellulose(BC) in the context of the application of advanced energy storage devices LIBs and green materials nanocellulose, and reviewed the research progress on the application of nanocellulose in the field of LIBs. It was mainly divided into three aspects: first, nanocellulose-based flexible LIBs electrodes; second, carbon materials derived from nano cellulose as electrodes; third, nano cellulose derived battery separator. Finally, some problems in this field were analyzed, summarized and prospected.更多还原
