纤维素滤纸基陶瓷复合隔膜的可控制备及其在锂离子电池中的应用研究
Controlled Fabrication of Cellulose Filter Paper-based Ceramic Composite Separators and Their Application in Lithium-Ion Batteries
摘要
Abstract
In this study,a cellulose filter paper-based ceramic composite separator was fabricated by constructing a chitosan/polyvinyl alco-hol/barium titanate multifunctional coating on low-cost paper substrates through an in-situ wet-coating technique.By regulating the disper-sion of ceramic fillers and the polymer cross-linking network,the controllable construction of a three-dimensional porous structure for the composite separator was successfully achieved.The results showed that when the mass fractions of chitosan,polyvinyl alcohol,and barium ti-tanate were 0.25%,1.0%,and 0.1%,respectively,the as-prepared composite separator exhibits exceptional comprehensive performance:enhanced thermal stability at 200℃with no dimensional shrinkage,a first-cycle discharge specific capacity of up to 118.69 mAh/g at 0.5 C in full-cell configuration,and an ultra-low charge transfer resistance of merely 6.87 Ω for the stainless steel/composite separator/half-cell.关键词
