| 英文摘要 | a dinitrile compound containing ethylene oxide moiety (4,7-dioxa-1,10-decanedinitrile, neon) is synthesized as an electrolyte solvent for high-voltage lithium-ion batteries. the introduction of ethylene oxide moiety into the conventional aprotic aliphatic dinitrile compounds improves the solubility of lithium hexafluorophosphate (lipf6) used commercially in the lithium-ion battery industry. the electrochemical performances of the neon-based electrolyte (0.8 m lipf6 + 0.2 m lithium oxalyldifluoroborate in neon:ec:dec, v:v:v = 1:1:1) are evaluated in graphite/li, licoo2/li, and licoo2/graphite cells. half-cell tests show that the electrolyte exhibits significantly improved compatibility with graphite by the addition of vinylene carbonate and lithium oxalyldifluoroborate and excellent cycling stability with a capacity retention of 97 % after 50 cycles at a cutoff voltage of 4.4 v in licoo2/li cell. a comparative experiment in licoo2/graphite full cells shows that the electrolyte (neon:ec:dec, v:v:v = 1:1:1) exhibits improved cycling stability at 4.4 v compared with the electrolyte without neon (ec:dec, v:v = 1:1), demonstrating that neon has a great potential as an electrolyte solvent for the high-voltage application in lithium-ion batteries. |
