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).

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）。
