In this work, different concentrations of lithium iodide (LiI) have been added to the gel polymer electrolyte (GPE) containing PEO and PVA in equal ratio, tetrabutylammonium iodide (TBAI), ethylene carbonate (EC), dimethyl sulfoxide (DMSO) and iodine crystals (I2). The effect of introducing lith...

Lithium sulfur battery is one of the most cost-effective alternatives to meet the requirement of high energy density for power sources due to its high energy density and low cost. However, lithium sulfur battery still suffers from a rapid capacity fading and poor rate performance, which are main...

Absorption refrigerators are expected for automotive use due to their advantage of utilizing waste heat from exhaust gas. The compactness and efficiency of the refrigeration system required for such use indicates a pair of water/lithium bromide (LiBr) as a promising working fluid. However, opera...

While grain conductivity of lithium titanium phosphate materials (LTP) is high, the total conductivity is relatively low due to high resistant grain boundary phase. The work demonstrates that this resistance can be substantially reduced by helps of LiI. For this purpose a series of the LTP–LiI ...

Recovery of lithium from lithium-rich electrolytes has attracted worldwide attention because of issues related to the electrolytic production of aluminum and its environmental impacts. Lithium carbonate preparation from a lithium-rich electrolyte by H2SO4 leaching, followed by removal of impurit...

A novel process for extracting lithium from carbonate subtype and sulfate type salt-lakes of Tibet by making full use of local resources and energy was developed. In this research, we extract lithium from carbonate subtype and sulfate type salt-lakes of Tibet through following three steps: carbo...

We report the synthesis of colloidal graphene via electrochemical exfoliation of graphite in Li2SO4 aqueous solution. In this electrochemical exfoliation method, high quality graphene was prepared within short time of 1.5 hr. This electrochemical exfoliation mechanism suggests that SO42- and H2O...

Lithium salts are known to have remarkable effect to restrain alkali aggregate reaction, but the influence on strength and setting time of cement paste is uncertain. This paper presents an experimental approach to study the influence of lithium sulfate on strength and setting time of ordinary Po...

The anticipated increase in demand for lithium salt brings a growing concern over lithium shortage and environmental problems in the industry of extracting lithium from ores. A closed-loop process for the extraction of lithium from β-spodumene (β-LiAlSi2O6) by leaching with Na2SO4, the by-prod...

Lithium slag (LS) blended cement mortar was prepared under two replacement levels (0 wt% and 20 wt%) and two curing regimes (initial steam curing for 7 h and initial standard curing), and their hydration products and performances under partial immersion in 5 wt% sodium sulfate solution were inve...

Brine from natural salt lakes (salt brine) is an important source of lithium; consequently the recovery of lithium from brine eluates prepared through Li+ adsorption-desorption is economically important. The present paper describes a study on the direct crystallization of Li2SO4·H2O from synthe...

A piezoelectric current response to small applied mechanical pressure changes, as low as 1 Pa, in environmental 1 atm pressure conditions, is reported for Lithium Sulfate monohydrate (LSM) nano-crystals grown inside alumina pores. A higher piezoelectric sensitivity is obtained in crystals having...

Glycine Lithium Sulphate (GLS), a non-centrosymmetric semi organic NLO single crystals were grown from aqueous solution with dimension of 10 x 11 x 12 mm3 by slow evaporation technique at room temperature using water as the suitable solvent. Crystalline phase and information on unit cell measure...

Slurry preparation in a citric-acid-buffered aqueous solution at low pH has been established as a viable strategy for tackling the poor capacity retention of silicon electrodes. A number of studies ascribed the improved capacity retention to the formation of a silyl ester between the Si surface ...

Maturation, which consists of storing the electrode under humid atmosphere before drying and cell assembly, improves very significantly the cyclability of silicon-based composite electrodes made with an acidic binder. During maturation, the atmospheric-induced corrosion of the current collector ...

The titanium type lithium ion sieve (Ti-LIS) is usually considered as a promising lithium ion sieve (LIS) by the virtue of its superiorities in both stable structure and high adsorption capacity. Acidification process is a significant and necessary step for LIS application in the lithium adsorpt...

Naturally occurring polyamines like Putrescine, Spermidine, and Spermine are polycations which bind to the DNA, hence stabilizing it and promoting the essential cellular processes. Many synthetic polyamine analogues have been synthesized in the past few years, which have shown cytotoxic effects ...

Water soluble rhodium catalyst complexes are highly active in a microemulsion system stabilized by technical grade surfactants of the alkyl-polyglycolether type. At temperatures around 120 °C and pressures of 100 bar internal alkenes are hydroformylated with high regioselectivity. 7-Tetradecene...

The rhodium-catalysed hydroformylation of the post-metathesis product 7-tetradecene using aryl- (1) and ferrocenyl- (2) Schiff base derived precatalyst complexes was investigated. It was found that the reaction temperature (75–115 °C), pressure (30–60 bar, CO/H2 = 0.5–2) and 7-tetradecene-to...
