custom-made electrochemical energy storage devices abstract customizable electrochemical energy storage device represents a key technology for the realization of wearable and bio-integrated electronics. this perspective begins with a brief introduction of the drive for customizable electrochemical energy storage devices. the following section involves the first-decade development trajectory of the customizable electrochemical energy storage devices. it then discusses the challenges and the future directions of the customizable electrochemical energy storage devices, calling for customizable electrochemical energy storage devices that allow users to select, design and change the functions (including capacity, flexibility, shapes, and functionalities) according to real-world application scenarios. the leveraging of the customizable electrochemical energy storage devices will shed a light on smarter and programmable electrochemical energy storage devices to power future wearable and bio-integrated electronics. key content： the drive for customizable electrochemical energy storage devices the first-decade journey towards customizable ees devices

(聚吡咯/黑磷氧化物/石墨烯氧化物) honeycomb‐lantern‐inspired 3d stretchable supercapacitors with enhanced specific areal capacitance abstract traditional stretchable supercapacitors, possessing a thin electrode and a 2d shape, have limited areal specific areal capacitance and are incompatible with 3d wearables. to overcome the limitations of 2d stretchable supercapacitors, it is highly desirable to develop 3d stretchable supercapacitors with higher mass loading and customizable shapes. in this work, a new 3d stretchable supercapacitor inspired by a honeycomb lantern based on an expandable honeycomb composite electrode composed of polypyrrole/black‐phosphorous oxide electrodeposited on carbon nanotube film is reported. the 3d stretchable supercapacitors possessing device‐thickness‐independent ion‐transport path and stretchability can be crafted into customizable device thickness for enhancing the specific areal energy storage and integrability with wearables. notably, a 1.0 cm thick rectangular‐shaped supercapacitor shows enhanced specific areal capacitance of 7.34 f cm−2, which is about 60 times higher than that of the original 2d supercapacitor (120 mf cm−2) at a similar discharge rate. the 3d supercapacitor can also maintain a capacitance ratio of 95% even under the reversible strain of 2000% after 10 000 stretch‐and‐release cycles, superior to state‐of‐the‐art stretchable supercapacitors. the enhanced specific areal energy storage and the customizability in shapes of the 3d stretchable supercapacitors show immense promise in a wide range of applications in stretchable and wearable electronics. keywords 3d supercapacitors, black phosphorus, expandable honeycomb structures, flexible electronics, polypyrrole 原文链接：

nanowire composite abstract：although some progress has been made on stretchable supercapacitors, traditional stretchable supercapacitors fabricated by predesigning structured electrodes for device assembling still lack the device-level editability and programmability. to adapt to wearable electronics with arbitrary configurations, it is highly desirable to develop editable supercapacitors that can be directly transferred into desirable shapes and stretchability. in this work, editable supercapacitors for customizable shapes and stretchability using electrodes based on mechanically strengthened ultralong mno2 nanowire composites are developed. a supercapacitor edited with honeycomb-like structure shows a specific capacitance of 227.2 mf cm−2 and can be stretched up to 500% without degradation of electrochemical performance, which is superior to most of the state-of-the-art stretchable supercapacitors. in addition, it maintains nearly 98% of the initial capacitance after 10 000 stretch-and-release cycles under 400% tensile strain. as a representative of concept for system integration, the editable supercapacitors are integrated with a strain sensor, and the system exhibits a stable sensing performance even under arm swing. being highly stretchable, easily programmable, as well as connectable in series and parallel, an editable supercapacitor with customizable stretchability is promising to produce stylish energy storage devices to power various portable, stretchable, and wearable devices. 原文链接：https://onlinelibrary.wiley.com/doi/full/10.1002/adma.201704531

楼主，您好！早在1月就拜读了AM的那篇大作，当时就认为文章的思路很巧妙。我刚涉及超容的电极材料研究，目前还在组装阶段，就遇到了很多问题，想向你咨询一下，希望不吝赐教。我做的聚吡咯导电织物，单个电极材料测试时，电压窗口0.8V，组装后，电压窗口变成了0.5V，应该是我组装的问题，我看文献里大都还是0.8V，疑惑如下：1.用的PVA/H2SO4或PVA/H3PO4凝胶电解质，高温煮透后呈透明状态，在50℃左右浸泡电极材料2小时，取出后加隔膜组装，问题就出来了，很多文献中说等待电解质凝固，这个凝固的状态却不好控制，一不留神就干了，凝固到什么状态是比较合适的呢？2.组装时，三明治式的装置需要加压吗？如果加压，多大的压力比较合适？非常期待您的解答。 |
