A battery utilizing the Galvani potential difference between aqueous and organic phases is demonstrated. The battery consists of two organic redox electrolytes separated by an immiscible aqueous phase. The charge is stored by transferring a salt from the a ...
Chem. degrdn. at electrode/electrolyte interfaces in high-energy storage devices, such as Li-ion batteries, imposes durability challenges that affect their life and cost. In oxide electrodes, degrdn. is linked to the presence of redox active transition met ...
In the present study, a forged CoCrMo (ISO 5832-12) has been subjected to pulsed plasma treatment in a N-2/H-2 atmosphere at low temperatures (below 500 A degrees C). This treatment resulted in the formation of a layer composed by dispersed chromium nitrid ...
Pure Magneli Ti4O7 nanotube arrays (NTA) were successfully fabricated by reducing TiO2 NTA with hydrogen at 850 degrees C for 30 minutes. The microstructure, composition and electrochemical behavior of the prepared Ti4O7 NTA were characterized by means of ...
There is considerable interest in developing solid electrolytes for rechargeable lithium batteries as they have the potential to increase both energy d. due to incorporation of a lithium metal anode and safety of batteries due to the fact that they are non ...
Within the context of the electrical circuit modeling of batteries, this paper proposes an improvement of the most common electric equivalent circuit used for Lithium cells. The main improvement is based on the modeling of the so-called charge redistributi ...
As a promising cathode inheritor for lithium-ion batteries, the sulfur cathode exhibits very high theoretical volumetric capacity and energy density. In its practical applications, one has to solve the insulating properties of sulfur and the shuttle effect ...
The present work focuses on stress-corrosion mechanisms in soda-lime silica glass. Four-point beam-bending tests were performed on small specimens, measuring failure time in function of temperature and relative humidity. By using linear elastic fracture me ...
Replacing the liq. electrolyte in lithium batteries by a solid has been a long-standing goal of the battery industry due to the promise of better safety and the potential to produce batteries with higher energy densities. Recently, sym. polystyrene-block-p ...
Solid state diffusion is a very complex mechanism and, up until recent studies, such properties had mainly been conducted by macroscopic methods that do not yield true material properties. This has been a major problem for materials development regarding e ...
