摘要

萜烯是一类广泛存在于植物和海洋生物体内的天然碳氢化合物,萜烯树脂(TR)经乳化得到萜烯树脂乳液(ATRE)。本文采用ATRE/羧甲基纤维素(CMC)作为锂离子电池石墨负极粘结剂。差示扫描量热(DSC)测试表明ATRE/CMC能够混溶。优化TR/CMC比例,发现采用TR/CMC(3∶2,质量比)粘结剂制备的石墨电极在比容量和倍率性能优于目前商用丁苯橡胶(SBR)/ CMC粘结剂。

Abstract

Aquous terpene resin emulsion (ATRE) was prepared by the emulsification of natural terpene resins (TR) from many plants exudates and marine organisms. ATRE/carboxymethyl cellulose (CMC) were completely miscible by differential scanning calorimetry. ATRE/CMC composite was used as a binder for graphite electrode in Li-ion batteries in this paper. Optimized ratios of TR/CMC (3:2, by weight), the graphite electrode exhibits the higher specific capacity and better rate capability than that of the commercial styrene-butadiene rubber (SBR)/CMC binder.
