Insufficient battery capacity for long-term durability in standalone mode is a highly significant issue in modern power supply cells. Manufacturing problems of electric energy chemical sources is topical and feasible problem. Chemical sources of electric ... see more

Orthorhombic Na0.44MnO2 with an S-shape tunnel structure was successfully synthesized by a hydrothermal method. The Na0.44MnO2 material has lattice parameters of a = 9.0842 Å, b = 26.2889 Å, and c = 2.8245 Å. Scanning electron microscope analysis reveals ... see more

The electrochemical characteristics of the cathode material coated with carbon layer has been developed. Various carbon coating methods. There  has been carried out a comparative electrochemical analysis of the coated and uncoated with carbon cathode... see more

One of the renewable energy storage systems that can be used today is the aluminum ion battery. In this study, aluminum foil was used as anode, polyetylene polyprophylene (PE/PP) as separator, electrolyte from AlCl3/[EMIm]Cl and graphite coated corncob, a... see more

In the last two decades, a huge attention has been paid to lithium-ion batteries with cathode material based on lithium iron phosphate (LiFePO4). This material is quite environmentally friendly and thermally stable in a fully discharged state. One of the ... see more

Li-ion batteries are the key enabling technology in portable electronics applications, and such batteries are also getting a foothold in mobile platforms and stationary energy storage technologies recently. To accelerate the penetration of Li-ion batterie... see more

Intermediate temperature (IT) fuel cells using mixed conducting materials have been reported by many researchers by adopting different compositions, microstructures, manufacture processes and testing conditions. Most iop-Vop relationships of these button ... see more

The article is devoted to the study of the operating modes of a glow discharge with a coaxial hollow cathode in helium and neon gases. It is shown that the burning voltage of a discharge with a coaxial hollow cathode is lower than one with a cylindrical h... see more

This paper reports studying the effect of such highly active, surface-active modifying elements as Y, Hf, and La on the structure and properties of the Ni–Cr–Al system's consumable cathodes, which are used to apply heat-resistant coatings onto the gas-tur... see more
