چکیده
Li 2-3x Al x S (0 ≤ 0.1667) was prepared via the planetary ball-milling method. Diffuse reflection UV-Vis measurements revealed that band gap and electronic structure of 2 changed with formation defective S. Compared = 0, ionic conductivity for sample 0.1334 improved by ∼3 orders magnitude. The lithium movement activation energy pre-exponential factor A were found to be dependent on value. S, a ∼10-fold improvement in realized addition 3 . Additionally, all-solid-state Li-S battery cell performance also displayed an enhancement both initial capacity stability 0.1667 compared 0. This study highlighted importance intrinsic active materials (but not electrode) battery.

متن کاملRechargeable Sodium All-Solid-State Battery
A reversible plating/stripping of a dendrite-free metallic-sodium anode with a reduced anode/ceramic interfacial resistance is created by a thin interfacial interlayer formed in situ or by the introduction of a dry polymer film. Wetting of the sodium on the interfacial interlayer suppresses dendrite formation and growth at different discharge/charge C-rates. All-solid-state batteries were obtai...

All-inorganic solid-state sodium-sulfur batteries (ASSBs) are promising technology for stationary energy storage due to their high safety, high energy, and abundant resources of both sodium and sulfur. However, current ASSB shows poor cycling and rate performances mainly due to the huge electrode/electrolyte interfacial resistance arising from the insufficient triple-phase contact among sulfur ...

متن کاملLiMnPO4 nanoplate grown via solid-state reaction in molten hydrocarbon for Li-ion battery cathode.
Electrochemically active LiMnPO(4) nanoplates have been synthesized via a novel, single-step, solid-state reaction in molten hydrocarbon. The olivine-structured LiMnPO(4) nanoplates with a thickness of approximately 50 nm appear porous and were formed as nanocrystals were assembled and grew into nanorods along the [010] direction in the (100) plane. After carbon coating, the prepared LiMnPO(4) ...
