The lithium–air (oxygen) battery could offer significant improvements in gravimetric energy density compared to lithium-ion technology. A major barrier to realising this goal is the oxidative degradation of the electrolyte solution and the carbon at the positive electrode. Recently, the lithium–oxygen...
There are several approaches to generate Ov into BiOX, including using reaction reagents, temperature changes, light illumination, ultrasonic waves, and lithium intercalation. For instance, a hydrothermal process using ethylene glycol has been developed to prepare BiOCl-Ov, which was then modified with...
The rate performance improved significantly; for example, the discharge and charge voltages at 200 mA g−1 were in the range 2.0–4.0 V. These results indicate that the resistance of solid electrolytes is still a rate limiting factor. Therefore, improvement of lithium-ion conductivity and ...

Reactivity towards air or oxygen increases from lithium to cesium, and the intensity depends on state of subdivision and on presence or absence of moisture. Lithium normally ignites in air above its mp, while potassium may ignite after exposure to atmosphere, unless it is unusually dry. Rubidium...
and electrical energy efficiency. In this study, an organic compound, triethylsulfonium iodide, is found to act bifunctionally as both a redox mediator and a solid electrolyte interphase-forming agent for lithium-oxygen batteries. During charging, the organic iodide exhibits comparable lithium peroxide...
H2V3O8has been regarded as a compelling cathode material for aqueous zinc-ion batteries (AZIBs) owing to its elevated theoretical capacity, abundance of vanadium valence states, and advantageous layered configuration. Nonetheless, the intrinsically low conductivity and sluggish ionic reaction kinetics of...
This ivnention relates to an electrolyte film of Li, P, O, N, S compound used in Li or Li ionic battery. Its components can be expressed by a molecular formula: LiwPOxMySz, where 2x+3y+2z=5+w, w is approximately equal to 3, and the optimized iron electric conductance S/P ratio ...
Various formulations of organic carbonate-based electrolytes have been extensively studied and are prevalent in commercial battery applications.11,12,13 Ionic conductivity within the electrolyte is enhanced through the incorporation of lithium-based salts, with Li+ serving as the cation.
