This condition causes problems in the environment and has a negative impact on life, including health and economic problems. To provide added value to the utilization of water hyacinth, a synthesis and characterization of porous carbon from water hyacinth has been carried out which is used as a sulfur cathode matrix in lithium sulfur batteries. From the results of the N 2 adsorption-desorption test, the surface area of porous carbon was 297.7 m 2 /g and the total pore volume was 0.332 cm 3 /g. The results of the composite test showed that the sulfur content in the composite for a ratio of 1:2.5 was 60.6 wt%. The cathode of a lithium sulfur battery has been made from a composite with a thickness 100 mm and a sulfur loading of 2.80 mg/cm 2 . The initial discharge capacity of the battery is 264 mAh/g with a coulomb efficiency of up to 70%. Battery discharge capacity of 175.5 mAh/g at 50th cycle.","PeriodicalId":488952,"journal":{"name":"JIIF (Jurnal Ilmu dan Inovasi Fisika)","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135396798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
