Supercapacitors: Aligned Ionogel Electrolytes for High-Temperature Supercapacitors (Adv. Sci. 5/2019)

In the article number 1801337, Qigang Wang and co-workers report a self-initiated cryopolymerization method to prepare nanocomposite ionogels with hierarchical aligned pores for use in high temperature supercapacitors. Diffusion simulations based on X-ray tomographic 3D reconstructed images are used to explain the origins of the observed electrochemical enhancements in the aligned ionogels, which highlight the potential for structured materials in energy storage devices.
