TL;DR: In this paper, the rational design of nanostructured materials has addressed the challenges of batteries and electrochemical capacitors and led to high-performance electrochemical energy storage devices, which is a critical technology in this century.

TL;DR: In this paper, a dual-solvent system with 1 m lithium bis(fluorosulfonyl)imide (LiFSI) and 1,2-dimethoxyethane is used as co-solvents to enable higher ionic conductivity and much reduced interfacial resistance.

TL;DR: In this article, a facile and scalable method is developed for fabricating metal-air batteries based on the fact that the Prussian blue analogue Mn3[Co(CN)6]2•nH2O and gelatin-coated Ketjenblack carbon thermally decompose at 400 °C in air (i.e., without requiring high-temperature pyrolysis under inert conditions) to form porous spinel oxides and N-doped carbon materials.

TL;DR: It is found that binders with relaxation times on the order of 0.1 s gave the best cycling stability with 80% capacity maintained for over 175 cycles using large silicon particles and the more cross-linked binder showed markedly worse performance confirming the need for liquid-like flow in order for the self-healing polymer electrode concept to be effective.

TL;DR: By using carbon nanocatalysts, heavy crude oil can be efficiently upgraded to lighter oil at a relatively low temperature of about 150 °C and has the following advantages: great viscosity reduction ratio over 96%, short reaction time, low required temperature, and long viscosities regression time.
