Discharge Capacity of Energy Storages as a Function of the Discharge Current–Expanding Peukert’s equation

International Journal of Electrochemical Science, 2017
In 1897 Wilhelm Peukert tested lead-acid batteries with constant current and observed that a single equation can describe the relationship between the discharge capacity of the battery and a constant discharge current.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Fabrication Routes for Ionic Conducting Fiber Strain Sensors

Advanced Engineering Materials, EarlyView.
Ionic conducting fiber strain sensors (ICFSs) offer compliant, textile‐integrable sensing. Thus far, the commercialization of ICFSs has been constrained by fiber fabrication routes. This review provides a fabrication‐centric analysis of ICFSs correlating processing strategies with material properties and scalability.

Kinetics and Electrochemical Studies of Fe-substituted LiMnPO4

International Journal of Electrochemical Science, 2012
A simple sol-gel method was applied to synthesize LiMn(1-x)FexPO4 (x=0-0.5). The kinetics of LiMn(1-x)FexPO4 was studied by chemical delithiation experiment and EIS measurements. The results showed that the LiMn0.6Fe0.4PO4 has the fastest conversion rate

Materials‐Driven Additive Manufacturing for Electrical Machines: Qualification‐Oriented Design Beyond Geometric Freedom

Advanced Engineering Materials, EarlyView.
This perspective reframes additive manufacturing for electrical machines as a qualification‐limited materials and architecture design problem. It links process–structure–property–performance relationships to magnetic, conducting, dielectric, and thermal property windows, highlighting where AM can enable segmented magnetic circuits, permanent magnet ...

Developing the Discharge Capacity of Al Husa'chi River

Engineering and Technology Journal, 2009
Al Husa'chi River is one of the three main branches of Al Ka’hla River in Maissangovernorate. Its length is 25 km. the river directly feeds Al Huwayza Marsh by overpasspipes at its end. It is also used for irrigating the nearby agricultural areas. A study forevaluating the hydraulic performance of the river has been carried out in order to developits ...

Enhancing Low‐Temperature Performance of Sodium‐Ion Batteries via Anion‐Solvent Interactions

Advanced Functional Materials, EarlyView.
DOL is introduced into electrolytes as a co‐solvent, increasing slat solubility, ion conductivity, and the de‐solvent process, and forming an anion‐rich solvent shell due to its high interaction with anion. With the above virtues, the batteries using this electrolyte exhibit excellent cycling stability at low temperatures. Abstract Sodium‐ion batteries
