The paper summarizes the results of studying how the temperature of the heat treatment of petroleum coke in a nitrogen flow influences its physicochemical and electrochemical properties. Petroleum coke was kept for 5 h in a nitrogen flow at fixed temperatures of 450, 600, 800, 1000, and 1200°C. Heat treatment of petroleum coke leads to a significant decrease in the specific resistivity (from 4.8 × 107 to 1 × 10–2 Ω cm), to an increase in the specific surface area, and to a decrease in the pycnometric density (the temperature of 1200°C is an exception). Petroleum coke that has not been heat-treated or has been heat-treated at 450 °С exhibits no electrochemical activity. The carbon electrodes made of petroleum coke heat-treated at 600°C in a nitrogen atmosphere exhibit the maximal anodic capacity for lithium (340–350 mA h/g). However, carbon electrodes based on petroleum coke heat-treated at 600°С exhibit short cyclic duration and high irreversible capacity (58–60%). An increase in the petroleum coke heat treatment temperature to 1200°С leads to a decrease in the irreversible capacity to 40% and in the reversible anodic capacity to 220 mA h/g and to an increase in the cycling duration of the carbon electrodes. The petroleum coke heat-treated un a nitrogen atmosphere at 1000°C is the most promising material for negative electrodes of lithium-ion batteries from the viewpoint of the set of physicochemical and electrochemical properties.","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"96 8","pages":"780 - 787"},"PeriodicalIF":0.6,"publicationDate":"2024-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140797801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structural features of the coating are described. Irrespective of the vibrational mixing conditions, thin coatings are layers with pronounced relief. Examination of the cross sections shows that the basic fragments forming the relief are metal–ceramic fragments consisting of SiC particles and nickel. A detailed study of thin sections shows that a nickel film is present on the surface of each particle, which indicates that the metal is reduced, in particular, on the particle surface. In the structure of thick composite coatings, agglomerations of SiC particles are also revealed. A coating formation mechanism consisting in the adsorption of SiC particle agglomerates and instantaneous nickel deposition on their surface was suggested. The results of analysis of the coating metal matrix by backscattered electron diffraction agree with the suggested mechanism.","PeriodicalId":757,"journal":{"name":"Russian Journal of Applied Chemistry","volume":"96 7","pages":"737 - 746"},"PeriodicalIF":0.6,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140598463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
