The increased focus on green energy storage devices and the related rapid advancement in biomedical technologies makes the investigation of biocompatible integrated systems with medical relevance increasingly important. Peptides and their assembled morphologies with their innate biocompatibility and biodegradability are emerging as promising candidates in this respect due to their structural attributes which can be easily tuned to form supramolecular 3D architectures with extended pathways for ionic mobility. However, to comprehend their applicability in energy storage devices, it is crucial to explore their self-assembling characteristics, charge-storage mechanisms, and coating efficacies. Herein, all these aspects are compiled with specific emphasis on peptide-based systems for supercapacitor applications. The electrochemical charge storage mechanisms that are used for categorizing conventional supercapacitors with the theories and mechanisms outlining biological electron transfer, such as tunneling, hopping, superexchange, and flickering resonance, are collated. Furthermore, the characterization techniques solely pertaining to the study of such systems and their role in predicting the morphology of self-assembly patterns which could directly impact the overall electrochemical properties are also addressed. Finally, some of the critical challenges associated with these systems while realizing their future potential in the field of sustainable energy storage devices are highlighted.
对绿色储能设备日益增加的关注以及生物医学技术的相关快速发展，使得对具有医学相关性的生物相容性集成系统的研究变得越来越重要。肽及其组装形态因其固有的生物相容性和生物降解性，正成为这方面有前景的候选者，这是由于它们的结构属性可以很容易地进行调整，以形成具有扩展离子迁移途径的超分子三维结构。然而，为了理解它们在储能设备中的适用性，探索它们的自组装特性、电荷存储机制和涂层效率至关重要。在此，所有这些方面都进行了汇总，特别强调了用于超级电容器应用的基于肽的系统。整理了用于对传统超级电容器进行分类的电化学电荷存储机制，以及概述生物电子转移的理论和机制，如隧穿、跳跃、超交换和闪烁共振。此外，还讨论了仅与此类系统研究相关的表征技术，以及它们在预测可能直接影响整体电化学性能的自组装图案形态方面的作用。最后，强调了在实现这些系统在可持续储能设备领域的未来潜力时与它们相关的一些关键挑战。
