The AsF6 anion, in the crystalline polymer electrolyte PEO6:LiAsF6, was replaced with the larger N(SO2CF3)2 anion. This produced an increase in the room temperature ionic conductivity of 1.5 orders of magnitude. It is believed that the enhancement is the result of the disruption of the electrostatic field around the lithium ions. The presence of the large and asymmetrical N(SO2CF3)2 ion creates...

The article is concerned with hybrid amorphous polymers synthesized basing on epoxy oligomer of diglycide aliphatic ester of polyethylene glycol that was cured by polyethylene polyamine and lithium perchlorate salt. Structural peculiarities of organic-inorganic polymer composites were studied by differential scanning calorimetry, wide-angle X-ray spectra, infrared spectroscopic, scanning electr...

To the average person, lithium-ion technology, at least until the last year or so, was represented by the black-box-like batteries in high-end consumer devices such as laptop computers. Mobile phone batteries use similar chemistry, although in that case the batteries are often lithium-polymer types that are frequently described as if they constitute an entirely different technology. The mystiqu...

We compare the physical properties and solution conductivities of three new lithium orthoborate salts with those of the well known slat lithium bis(trifluoromethanesulfony)imide LiTFSI. The three new lithium salts are lithium bis(perfluoropinacolato)borate (LiBPFPB), lithium bis(oxalato)borate (LiBOB) and lithium bis(malonato)borate (LiBMB). Computational models of the three orthoborate anions ...

Solid-state electrolytes provide substantial improvements to safety and electrochemical stability in lithium-ion batteries when compared with conventional liquid electrolytes, which makes them a promising alternative technology for next-generation high-energy batteries. Currently, the low mobility of lithium ions in solid electrolytes limits their practical application. The ongoing research ove...

Baterai lithium-ion-polymer atau lithium-polymer merupakan salah satu jenis dari baterai berbasis lithium-ion. Saat ini, Lithium-ion banyak digunakan pada berbagai macam perangkat portabel hingga kendaraan listrik. Pengisi daya charger untuk yang umum saat ini menggunakan metode constant current – voltage (CC-CV). Metode dianggap efektif menghindari undercharging dan overcharging. Pada battery ...

Polymer composite electrolytes (PCEs), i.e., materials combining the disciplines of polymer chemistry, inorganic and electrochemistry, have received tremendous attention within academia industry for lithium-based battery applications. While PCEs often comprise 3D micro- or nanoparticles, this review thoroughly summarizes prospects 2D layered inorganic, organic, hybrid nanomaterials as active (i...

Mixed-conducting lithium-ion doped emeraldine polyaniline (PAni)–polyethylene oxide (PEO) blends have been developed to achieve an optimal electronic– ionic conductivity balance in nano-tin composite anodes. Electrochemical evaluation was performed on the anodes with differing electrode preparation procedures, doping methods and PEO contents. Results indicate that both good electronic and ionic...

Sol-gel derived poly(oxyethylene)/siloxane hybrids doped with lithium hexafluoroantimonate, LiSbF6, have been prepared. Compositions of these novel xerogel electrolytes were identified using the conventional d-U(2000)nLiSbF6 notation, (where n is the molar ratio of oxyethylene moieties per Li + ion) and samples with n between ∞ and 2.5 were characterized by conductivity measurements, cyclic vol...
