High-molecular-weight, carbohydrate based Solid Biopolymer Electrolyte (SBE) pectin-lithium perchlorate [C₆H₁₀O₇:LiClO₄ = 60:40 molar mass percentage (m.m.%)] with ethylene carbonate (EC) as plasticizer has been prepared by simple solution casting technique. Addition of EC results in enhanced electrochemical window from 3.39 V to 3.55 V. The flexibility of the SBE is also improved which leads to attain an enriched ionic conductivity of 3.89 × 10⁻⁴ Scm⁻¹ in the sample with optimum salt and plasticizer composition. The eco-friendly membrane with highest conductivity contributes good cycling properties and possesses higher value of cationic transference number when compared with other electrolyte samples. A lithium ion conducting battery constructed using the highly conducting polymer membrane sample is used to light up the red LED, display an Open Circuit Voltage (OCV) of 1.65 V.

高分子量，基于碳水化合物的固体生物聚合物电解质（SBE）果胶-高氯酸锂[C ₆ H ₁₀ O ₇：LiClO ₄  = 60:40摩尔质量百分比（mm％）]已经使用碳酸亚乙酯（EC）作为增塑剂。通过简单的溶液浇铸技术制备。添加EC可使电化学窗口从3.39 V提高到3.55V。SBE的柔韧性也得到了改善，从而获得了3.89×10 ^-4 Scm ^-1的富离子电导率。在样品中具有最佳的盐和增塑剂组成。与其他电解质样品相比，具有最高电导率的环保膜具有良好的循环性能，并具有更高的阳离子转移数值。使用高导电聚合物膜样品构建的锂离子导电电池用于点亮红色LED，显示1.65 V的开路电压（OCV）。
