The electrochemical behavior of the lithium hexagonal tungsten bronze, LixWO3, is investigated herein. material was synthesized at a low temperature under hydrothermal conditions, yielding nanorod-like particles with growth along c-axis. Upon cycling in 5 M LiNO3 aqueous electrolyte, specific capacity 71 C.g−1 obtained 2 mV.s−1, corresponding to charge/discharge cycle 10 min. charge storage mec...

A conducting lithium aluminum germanium phosphate (LAGP) glass-ceramic with a formula of Li1.5Al0.5Ge1.5(PO4)3 was synthesized by melt-quenching method and subsequent crystallization at 850 °C for 8 h. The prepared glass-ceramic was characterized using differential scanning calorimetry (DSC), X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and AC impedance techniqu...

Congruently melting salt hydrates absorb and release heat reversibly upon solidification, have among the highest energy density thermal conductivity of low point (<50 °C) phase change materials. However, very few hydrate systems been identified that congruently melt near room temperature, which limits their utility in environmental control applications. Here we present thermochemical thermophys...

Electrolyte additives have been widely used to address critical issues in current metal (ion) battery technologies. While their functions as solid electrolyte interface forming agents are reasonably well-understood, interactions the liquid environment remain rather elusive. This lack of knowledge represents a significant bottleneck that hinders development improved systems. Here, key role promo...

Inductively-coupled thermal plasma processes were used to produce nanosized Li2S. Prior the syntheses, feasibility of forming Li2S was first evaluated using FactSage by considering phase diagrams sulfur and different lithium precursors in reducing atmospheres; Li2O, LiOH·H2O, Li2CO3 Li2SO4·H2O all showed promises producing nanoparticles, as confirmed experiments. Argon hydrogen mixtures gases, ...

The changes in global energy trends and the high demand for secondary power sources, have led to a renewed interest aqueous lithium-ion batteries. selection of suitable anode media is difficult task because many materials poor cycling performance due side reactions with water or dissolved oxygen. An effective method improving characteristics anodes electrolyte solutions adding carbon nanotubes ...

Despite the large number of studies on the behavior of LiCoO2 in organic electrolytes and its recent application as a positive electrode in rechargeable water battery prototypes, a little information is available about the lithium intercalation reaction in this layered compound in aqueous electrolytes. This work shows that LiCoO2 electrodes can be reversibly cycled in LiNO3 aqueous electrolytes...

This paper proposes an alternative for the calculation of liquid entropy binary solutions is proposed in this form correlation equations with higher computation speed. These were obtained by using both least squares method modelling reference and a classical matrix computer solving modeling entropy. Goodness-of-fit parameters such as sum estimation errors (SSE), Pearson's factor (R-squared), ro...
