Pickering emulsion polymerization of polyaniline/LiCoO2 nanoparticles used as cathode materials for lithium batteries

Concurrently Approaching Volumetric and Specific Capacity Limits of Lithium Battery Cathodes via Conformal Pickering Emulsion Graphene Coatings

“…Pickering emulsions result from two immiscible solvents, where solid-state emulsifiers stabilize the interfaces of the emulsion droplets. Because of its benefits for mass production and controllability, Pickering emulsions have been previously utilized in batteries for in situ polymerization [16] and hollow carbon structures [17] . In our experiments, as the first step in achieving a conformal graphene coating, a Pickering emulsion was formed using acetonitrile and hexane as immiscible solvents and graphene (Gr) as a This article is protected by copyright.…”

Application of polyaniline and polypyrrole in electronics

“…При использовании в качестве материала катода композита полианилин/LiCoO 2 увеличивается не только электронная проводимость по сравнению с исходным LiCoO 2 , но и обратимость реакции. В результате может быть достигнуто увеличение удельной емкости с 136 мА×ч×г -1 до 167 мА×ч×г -1 [21]. Другой распространенный материал для изготовления катода -LiFePO 4 , обеспечивающий стабильность цикла заряда и разряда, а также значительную термостойкость, обладает низкой электронной и ионной проводимостью, что ограничивает возможности его применения при конструировании литий-ионных батарей.…”

Polymer particles armored with cobalt oxide nanosheets for the catalytic degradation of bisphenol A

“…One example is the use of oil-in-water (o/w) Pickering emulsions to prepare composites of LCO nanoparticles and polyaniline as the positive electrode in a lithium battery; the discontinuous phase of the emulsion was aniline dissolved in toluene and LCO particles served as surfactant. 40 Alternatively, Span-80 was used to stabilize aqueous droplets of lithium acetate and cobalt acetate in a continuous phase of kerosene for the synthesis of ultrafine LCO powder, with each droplet acting as a tiny reaction vessel. 41 In a similar vein to the use of salt-flocculated LAPO-NITE s clay nanosheets, 42 our groups recently demonstrated that oil-in-water emulsions can be stabilized by a combination of CONs and GO nanosheets when flocculated with salt.…”
