A polymer electrolyte was developed by blending lithium (LiPAA) with non-ionic polyacrylamide (PAM). The LiPAA-PAM showed synergic effect and achieved an ionic conductivity of 13.8 ± 2.4 mS cm−1, higher than previously developed neutral pH polymer electrolytes. Chemical and structural characterizations of the LiPAA-PAM films revealed a stable homogeneous amorphous structure. The performance of double layer capacitors using LiPAA-PAM electrolyte system was demonstrated using YP-50F activated carbon electrodes. These solid cells demonstrated wide voltage window (1.5 V), good cycle life (>10,000 cycles), and excellent rate capability (up to 500 mV s−1 in cyclic voltammetry).

聚丙烯酸锂-聚丙烯酰胺共混物作为固态电化学电容器的聚合物电解质

通过将锂(LiPAA)与非离子聚丙烯酰胺(PAM)共混来开发聚合物电解质。LiPAA-PAM显示出协同作用,并实现了13.8±2.4 mS cm -1的离子电导率,高于先前开发的中性pH聚合物电解质。LiPAA-PAM膜的化学和结构表征显示出稳定的均匀无定形结构。使用YP-50F活性炭电极证明了使用LiPAA-PAM电解质系统的双层电容器的性能。这些固态电池显示出宽电压窗口(1.5 V),良好的循环寿命(> 10,000次循环)和出色的倍率能力(循环伏安法中高达500 mV s -1)。
