摘要

可伸缩性是柔性一体化超级电容器的一个重要特性。本研究报道了一种新型水凝胶电解质--聚丙烯酰胺-二乙烯基苯-Li2SO4(PAM-DVB-Li),该电解质的合成采用了疏水节点与亲水网络相结合的策略,以及通过胶束将疏水 DVB 交联剂分散到丙烯酰胺单体/Li2SO4 水溶液中,然后进行γ 辐射诱导聚合和交联的方法。最终得到的 PAM-DVB-Li 水凝胶电解质具有优异的机械性能,拉伸度为 5627 ± 241%,离子电导率高达 53 ± 3 mS cm-1。通过在 PAM-DVB-Li 水凝胶电解质上原位聚合导电聚苯胺 (PANI),进一步制备出了具有高度集成结构的新型一体化超级电容器 PAM-DVB-Li/PANI。得益于水凝胶电解质的优异性能和一体化结构,该器件在 0.5 mA cm-2 电流条件下的比电容高达 469 mF cm-2,并具有良好的循环稳定性、安全性和抗形变破坏性。更重要的是,该器件的抗拉强度(在不超过 300% 的应变下正常工作,1000% 拉伸 1000 次和 3000% 拉伸 10 次的电容稳定性)远远超过了其他一体化超级电容器。这项研究提出了一种构建抗拉伸一体化柔性超级电容器的新策略,这种电容器可用作可拉伸电子设备的储能装置。

An Ultrastretchable and Highly Conductive Hydrogel Electrolyte for All-in-One Flexible Supercapacitor With Extreme Tensile Resistance

An Ultrastretchable and Highly Conductive Hydrogel Electrolyte for All-in-One Flexible Supercapacitor With Extreme Tensile Resistance
Stretchability is a crucial property of flexible all-in-one supercapacitors. This work reports a novel hydrogel electrolyte, polyacrylamide-divinylbenzene-Li2SO4 (PAM-DVB-Li) synthesized by using a strategy of combining hydrophobic nodes and hydrophilic networks as well as a method of dispersing hydrophobic DVB crosslinker to acrylamide monomer/Li2SO4 aqueous solution by micelles and followed γ-radiation induced polymerization and crosslinking. The resultant PAM-DVB-Li hydrogel electrolyte possesses excellent mechanical properties with 5627 ± 241% stretchability and high ionic conductivity of 53 ± 3 mS cm−1. By in situ polymerization of conducting polyaniline (PANI) on the PAM-DVB-Li hydrogel electrolyte, a novel all-in-one supercapacitor, PAM-DVB-Li/PANI, with highly integrated structure is prepared further. Benefiting from the excellent properties of hydrogel electrolyte and the all-in-one structure, the device exhibits a high specific capacitance of 469 mF cm−2 at 0.5 mA cm−2, good cyclic stability, safety, and deformation damage resistance. More importantly, the device demonstrates a superior tensile resistance (working normally under no more than 300% strain, capacitance stability in 1000 cycles of 1000% stretching and 10 cycles of 3000% stretching) far beyond that of other all-in-one supercapacitors. This work proposes a novel strategy to construct tensile-resistant all-in-one flexible supercapacitors that can be used as an energy storage device for stretchable electronic devices.

期刊介绍: Energy & Environmental Materials (EEM) is an international journal published by Zhengzhou University in collaboration with John Wiley & Sons, Inc. The journal aims to publish high quality research related to materials for energy harvesting, conversion, storage, and transport, as well as for creating a cleaner environment. EEM welcomes research work of significant general interest that has a high impact on society-relevant technological advances. The scope of the journal is intentionally broad, recognizing the complexity of issues and challenges related to energy and environmental materials. Therefore, interdisciplinary work across basic science and engineering disciplines is particularly encouraged. The areas covered by the journal include, but are not limited to, materials and composites for photovoltaics and photoelectrochemistry, bioprocessing, batteries, fuel cells, supercapacitors, clean air, and devices with multifunctionality. The readership of the journal includes chemical, physical, biological, materials, and environmental scientists and engineers from academia, industry, and policy-making.
