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。
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.
