摘要

利用经典分子动力学，本研究研究了石墨烯基超级电容器，该电容器采用氨基酸离子液体（[emim] +与甲硫酸盐、苯丙酸盐或丝氨酸盐配对），控制水合（0 - 40%）。对双电层结构、离子分布和电位分布的分析表明，适度含水量（10 - 20%）可以通过改善界面有序来提高电容和能量密度，而不会造成明显的电压损失。以苯丙氨酸为基础的电解质提供最高的能量储存，而丝氨酸在水合水平下提供稳定性，蛋氨酸显示出明显的水合驱动增益。这些离子液体的可生物降解性强调了它们在可持续、高性能储能设备方面的前景。

Biodegradable ionic liquids in energy storage: Molecular insights into hydration-controlled performance in graphene-based supercapacitors

Using classical molecular dynamics, this work investigates graphene-based supercapacitors employing amino acid ionic liquids ([emim] + paired with methioninate, phenylalaninate, or serinate) with controlled hydration (0–40 %). Analysis of electric double layer structure, ion distribution, and potential profiles suggests that moderate water content (10–20 %) tends to enhance capacitance and energy density by improving interfacial ordering without significant voltage loss. Phenylalanine-based electrolytes deliver the highest energy storage, while serine offers stability across hydration levels and methionine shows pronounced hydration-driven gains. The biodegradability of these ionic liquids underscores their promise for sustainable, high-performance energy storage devices.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
