Na2Ti3O7: Lowest voltage ever reported oxide insertion electrode for sodium ion batteries

TL;DR: In this paper, Na2Ti3O7 is found to reversibly uptake 2 Na ions per formula unit (200 mA h/g) at an average potential of 0.3 V and is hence a very promising negative electrode material for building sodium ion bat...
Journal ArticleDOI

Real-Time NMR Investigations of Structural Changes in Silicon Electrodes for Lithium-Ion Batteries

TL;DR: A spontaneous reaction of the lithium silicide with the electrolyte is directly observed in the in situ NMR experiments; this mechanism results in self-discharge and potential capacity loss.
Journal ArticleDOI

Interface Stability of Argyrodite Li6PS5Cl toward LiCoO2, LiNi1/3Co1/3Mn1/3O2, and LiMn2O4 in Bulk All-Solid-State Batteries

TL;DR: In this article, the interface stability of argyrodite Li6PS5Cl was investigated for all-solid-state Li-ion half-cells and the interface mechanisms were characterized by Auger electron spectroscopy and X-ray photoelectron spectrographs.
Journal ArticleDOI

An all-solid state NASICON sodium battery operating at 200 °C

TL;DR: In this paper, an all-solid state symmetric monolithic sodium ion battery operating at 200°C was described, using NASICON-type electrodes and electrolyte, and the full battery was assembled in a 10′ single step by spark plasma sintering at 900°C.
Journal ArticleDOI

Structural and Mechanistic Insights into Fast Lithium-Ion Conduction in Li4SiO4–Li3PO4 Solid Electrolytes

TL;DR: Solid-state (6)Li, (7) Li, and (31)P NMR experiments reveal enhanced local Li-ion dynamics and atomic disorder in the solid solutions, which are correlated to the ionic diffusivity.
