TL;DR: The preparation of thick electrode all-solid-state lithium-ion cells in which a large geometric capacity of 15.7 mAh cm-2 was achieved at room temperature using a 600 μm-thick cathode layer was reported.

TL;DR: An operando diffraction technique that uses high-intensity neutrons to detect reactions in non-equilibrium states driven by high-current operation in commercial 18650 cells is reported, providing valuable information required for the development of advanced batteries.

TL;DR: The atomic and electronic structures of binary Li2S-P2S5 glasses used as solid electrolytes are modeled by a combination of density functional theory (DFT) and reverse Monte Carlo (RMC) simulation and it is found that the edge sharing between PSx and LiSy polyhedra increases at a highLi2S content, and the free volume around PSx polyhedRA decreases.

TL;DR: In this paper, Na 4 Co 2.4 Co 3 (PO 4 ) 2 P 2 O 7 has been evaluated as a positive electrode for sodium-ion batteries and two redox couples around 4.2 and 4.6 V were found to provide high mixed potential by the reactions of Co, Mn and Ni ions.

TL;DR: In this paper, a specific observation technique to visualize the precipitated nanocrystallites via transmission electron microscopy (TEM) and a quantitative method for evaluating the crystallization degree are developed.
