In this work, graphite-based negative electrode for lithium-ion battery consisting a novel and biodegradable binder poly(hydroxybutyrate-co-hydroxyvalerate) (PHBV) is compared with standard graphite electrode with polyvinylidene fluoride (PVDF) as a binder. The rate and cycling performance of lithium ion insertion/extraction of electrodes with PHBV in a half-cell configuration are evaluated. Moreover, on the basis of the electrochemical tests it is concluded that the electrode with PHBV binder is characterized by similar specific capacity and diffusion coefficient of lithium ions as conventional graphite electrode with PVDF binder.

聚（羟基丁酸酯-共羟基戊酸酯）作为锂离子电池负极材料中的可生物降解粘合剂

在这项工作中，将由新型可生物降解粘合剂聚（羟基丁酸-共-羟基戊酸）（PHBV）组成的锂离子电池石墨基负极与以聚偏二氟乙烯（PVDF）作为粘合剂的标准石墨电极进行了比较。评估了半电池配置中具有 PHBV 的电极的锂离子插入/提取的速率和循环性能。此外，基于电化学测试得出结论，具有 PHBV 粘合剂的电极具有与具有 PVDF 粘合剂的常规石墨电极相似的比容量和锂离子扩散系数的特征。
