Mohd Sarofil, Anith Dzhanxinah; Devina, Winda; Albertina, Ingrid; Chandra, Christian; Kim, Jaehoon published an article on February 25 ,2022. The article was titled 《Toad egg-like bismuth nanoparticles encapsulated in an N-doped carbon microrod via supercritical acetone as anodes in lithium-ion batteries》, and you may find the article in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands).Recommanded Product: Triacetonamine The information in the text is summarized as follows:
A toad egg-inspired structure comprising bismuth (Bi) nanoparticles (NPs) contained in a carbon microrod shell (Bi@C) was synthesized via the one-pot supercritical acetone (scAct) route and subsequent carbonization. During the formation of Bi NPs in scAct in the presence of nitric acid, a few decomposed acetone mols. acted as carbon sources, which generated an albumen-like N-doped carbon microrod with an average shell thickness of 38 nm and were embedded with yolk-like Bi NPs having size in the range of 30-200 nm. The densely packed Bi NPs inside the carbon micron shell resulted in a high Bi loading of 78 wt%. When utilized for Li storage, the Bi@C delivered a high reversible capacity of 337 mAh g-1 after 70 cycles at 0.05 A g-1, long-term cyclability of 0.04 decay per cycle for 1000 cycles at 1 A g-1, and high volumetric energy d. of 870 mAh cm-3. The use of a mixed ether- and ester-based electrolyte in the Bi@C cell reduced the resistivity and increased the capacitive contribution, thereby resulting in a better high-rate performance and long-term stability than those obtained using conventional ester-based electrolytes. The experimental part of the paper was very detailed, including the reaction process of Triacetonamine(cas: 826-36-8Recommanded Product: Triacetonamine)
Triacetonamine(cas: 826-36-8) is a member of piperidine. Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Hence, continuous efforts have been made to develop convenient methods to prepare piperidine derivatives.Recommanded Product: Triacetonamine
