Trifluoromethanesulfonamide ine CAS 421-85-2
Trifluoromethanesulfonamide chinhu chinoshandiswa mumakemikari, chinogona kugadzirwa nekuita kwe trifluoromethanesulfonyl chloride ne ammonia gas. Trifluoromethanesulfonyl inogona kushandiswa kugadzira LiTFSI. LiTFSI chinhu chinobatsira mumakemikari e organic chemabhatiri e lithium. Nekuda kwechimiro chemakemikari chakakosha chechikamu cheanion (CF3SO2)2N-, LiTFSI ine kugadzikana kwakanyanya kwe electrochemical uye conductivity yemagetsi; Zvichienzaniswa neLiClO4 neLiPF6, LiTFSI se electrolyte additive inogona: 1) kuvandudza firimu reSEI re positive ne negative electrodes; 2) kusimudzira interface ye positive ne negative electrodes; 3) kudzivirira kugadzirwa kwegasi; 4) kuvandudza mashandiro e cycle; 5) kuvandudza kugadzikana kwekupisa kwakanyanya; 6) kuvandudza mashandiro ekuchengetedza nezvimwe zvakanakira.
