Article
Batteries are major technological challenge in this new century as they are key method to make more efficient use of energy. Lithium batteries are characterized by high specific energy, high efficiency and long life. These unique properties have made lithium batteries the power sources of choice for the consumer electronics market with a production...
Article
Silicon is considered one of the most promising anode materials for high-performance Li-ion batteries due to its 4000 mAh/g theoretical specific capacity, relative abundance, low cost, and environmental benignity. However, silicon experiences a dramatic volume change (∼300%) during full charge/discharge cycling, leading to severe capacity decay and...
Article
During last two decades, lithium-based glasses have been studied extensively as electrolytes for solid-state secondary batteries. For practical use, solid electrolyte must have high ionic conductivity as well as chemical, thermal and electrochemical stability. Recent progresses have focused on glass electrolytes due to advantages over crystalline s...
Article
Sb2Se3, an important member of V2VI3 compound semiconductor, is a layer-structured semiconductor of orthorhombic crystal structure which exhibits good photo-voltaic properties and high thermoelectric power (TEP) which makes it to possess promising applications in photo-chemical devices, optical and thermoelectric cooling devices, decorative coating...
Article
LiCoO2 thin films have received attention as cathodes of thin-film microbatteries in these days. In the present work, LiCoO2 thin films were prepared by sol–gel spin-coating method with a polymer additive (PVP) and a post annealing process which was very effective for preparing crack-free thin film. We have deposited LiCoO2 thin films on silicon wa...
Article
Lithiated layered transitional metal oxide materials of the LiMO2 type and especially LiCoO2 presents interesting specific properties as high energy density, long cycle life and constant discharging properties in a wide range of working conditions as well as a good safety. These properties made these materials excellent candidates as active compoun...
Article
Low cost anode materials having a high electrochemical efficiency have been critical in the success of thin film batteries that are applicable in ubiquitous environments as a portable energy source. Nichrome thin films are ideally suited for use in hybrid assemblies but their applications include precision integrated circuits in fields of telecommu...
Article
New materials hold the key to fundamental advances in energy conversion and storage, both of which are vital in order to meet the challenge of global warming and the finite nature of fossil fuels. Nanomaterials in particular offer unique properties or combinations of properties as electrodes and electrolytes in a range of energy devices. Technologi...
Article
Bismuth antimony sulphide (Bi1?x,Sbx)2S3 thin films have been deposited on glass substrates using arrested precipitation technique. Ingredients used for the deposition include triethanolamine complex of bismuth, aqueous thioacetamide and antimony trichloride. Stoichiometric mixtures of these ingredients are used for deposition of thin uniform and a...
Conference Paper
Sb<sub>2</sub>S<sub>3</sub> thin films of different thickness have been prepared by chemical bath deposition method using bismuth nitrate and thioacetamide in an aqueous medium. Films were deposited onto ordinary as well as FTO coated glass substrates. The photoelectrochemical (PEC) cell configuration was n-Sb<sub>2</sub>S<sub>3</sub> / 0.25 M NaOH...
Article
Combinational thin films of antimony sulphoselenide [Sb2(S1_x Sex)3 ] have been synthesized on a good quality glass substrates using newly developed arrested precipitation technique (APT) by us. Sb(III) ions were arrested using aqueous alkaline solution of organic complexing agent. Highly reflecting uniform and tightly adhesive thin films were form...
Article
A method is proposed for the chemical compositional analysis of mixed chalcogenide semiconducting thin films. The technique presently used for extraction, separation and spectrophotometric determination of bismuth(III) and selenium(IV) from hydrochloric acid media with 1-(41-bromophenyl) 4,4,6-trimethyl 1,4 dihydropyrimidine 2-thiol (4l-bromo PTPT)...
Article
Bismuth sulphoselenide [Bi2(S,Se)3] thin films were obtained onto the thoroughly cleaned amorphous glass substrates using a simple chemical growth process. The basic ingredients used were analytical grade and a selenium source was obtained from a reflux action of the sodium sulphite with the metal selenium. Growth kinetics and mechanism of film for...
