In this paper, the flow dynamics of polymer greases was investigated using micro-particle image velocimetry. Polymer have a different thickener structure, compared to widely used lithium-based greases, and they well-known ability release oil. How these properties affect grease deformation its is corresponding behavior lithium complex with same consistency. Two main tests were carried out, where...

introduction: lithium salts are known as effective psychotropic medicine for treatment bipolar disorder and may be used to treat alcoholism, schizoaffective disorders, and cluster headaches. the antioxidant activity and immunomodulatory effects of prospective lithium compounds have been investigated in this work. materials and methods: the antioxidant properties were studied by the voltammetry ...

Solid-State Lithium Batteries In article number 2200206, Feng Li, Zhenhua Sun, and co-workers report a double crosslinked poly(ethylene oxide)-based polymer electrolyte by C-S-C groups metal-organic framework, which enables fast ion conduction high stability. This cathode-supported is developed for high-energy solid-state lithium batteries.

Interpenetrating Polymer Network Electrolyte In article number 2213469, Hsisheng Teng and co-workers demonstrate a robust solid-state lithium battery with synergy between O-based F-based polymer networks, which overpowers liquid electrolyte batteries in terms of safety performance. This synergistic relationship, combined the creation an anion-aggregate domain, expedites Li+ transport battery.

A hybrid solid electrolyte prepared by fast UV-photopolymerization of a single-ion polymer network and ceramic garnet LLZO nanoparticles with very high lithium conductivity is reported.

All-solid-state lithium-ion batteries (ASSLIBs) are promising alternatives to conventional organic electrolyte-based due their higher safety and energy densities. Despite advantages, ASSLIBs suffer from issues like high charge transfer resistances the brittleness of inorganic solid electrolyte chemical instabilities at lithium/electrolyte interface. Within this work, we investigate composite el...

Frequency dependent conductivity of amorphous polymeric solid electrolyte containing LiN(SO2CF3)2 (LiTFSI) or LiBF4 was studied. Successive heating and cooling cycles showed changeable conductivity behavior, which was due to chemistry change in the lithium salts. Both salts showed a tendency of decreasing conductivity in the second cooling process. The decrease in conductivity behavior for samp...

Three alkali cations, potassium, sodium, and lithium, have been separated within 15 s in a 1 cm long polymer microchip. The separation microchannel is modified by a polycation, poly(allylammonium chloride), which makes the channel surfaces positively charged leading to a reversed electroosmotic flow (EOF) when compared to bare channels. Due to the decreased apparent mobility of the cations, the...

The reduction of aluminium trichloride by lithium aluminium hydride in the presence of poly(vinylpyrrolidone) or poly(methylmethacrylate) in mesitylene yielded nano aluminium particles in the matrices of respective polymers. Solution phase synthesis methodology was used successfully to produce composites of various Al/polymer ratios. The composites were characterized by powder XRD patterns and ...
