VIP: Three-Dimensional Structural Engineering for Energy-Storage Devices: From Microscope to Macroscope

Jing Xu, Xianfu Wang, Xiaowei Wang, Di Chen,* Xiaoyuan Chen, Dongdong Li* and Guozhen Shen*

As typical energy-storage devices (ESDs), supercapacitors and Li-ion batteries have attained great research attention for their excellent electrochemical energy-storage performance and low cost. This article aims to review the recent achievements in these ESDs from three aspects: 3D active materials, 3D current collectors, and 3D device integrations, along the line of microscope to macroscope. The structural engineering in each section is categorized and summarized based on the results in the literature, shedding light on the importance of advanced architecture. In addition, some possible research trends about ESD configurations and an optimistic outlook are also proposed.

Coming soon.

    Two for the price of one: Electrodes modified with platinum and gold nanoparticles exhibit electrocatalytic synergy for glucose oxidation. Such a simple method of preparation of bimetallic nanoparticulate film produces an electrode with a significant shift in the onset potential compared to electrodes prepared only from platinum or gold nanoparticles.

  2. Inhibition of Cu Underpotential Deposition on Au Nanoparticles: The Role of the Citrate Capping Agent and Nanoparticle Size

    Probing inhibition: Given the importance of nanoparticle-based functional materials, understanding the altered adsorption and reactivity at these surfaces is of great interest. By comparing the underpotential deposition of Cu on a Au macroelectrode and nanoparticle surfaces, the influence of both the capping agent and the nanoparticle size are examined, revealing significant effects on the surface coverage of Cu.

  3. MnO2 Nanoflower Arrays with High Rate Capability for Flexible Supercapacitors

    Great things in small packages: Large-area α-MnO2 nanoflower arrays on flexible substrates are synthesized through a facial template-free electrochemical deposition process. These nanoflower arrays produce an enhanced electrochemical performance in the form of a high specific capacitance with remarkable rate capability and excellent cycling stability.

  4. Heterogeneous Catalysis of Multiple-Electron-Transfer Reactions at Nanoparticle-Modified Electrodes

    Control freak: The final product of important multistep electrode reactions, such as the electro-reduction of oxygen, depends on the extent of a surface-catalysed reaction and, therefore, on the nature and coverage of the nanoparticles employed for the electrode modification.

  5. Shielding of a Microdisc Electrode Surrounded by an Adsorbing Surface

    Article first published online: 26 MAR 2014 | DOI: 10.1002/celc.201400005

    Sheath shielding: It is shown that if significant adsorption occurs on the sheath used to insulate a microdisc electrode, then it can have a high impact on the measured current–time data because of a considerable shielding effect. Chronoamperograms are simulated as a function of the sheath-to-disc electrode radius ratio and the rate constant for adsorption onto the sheath.
