主 题:LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)/graphite battery High temperature performance H_(2)O/HF scavenger 2-Phenyl-1H-imidazole-1-sulfonate Electrolyte additive
摘 要:This work develops 2-Phenyl-1H-imidazole-1-sulfonate(PHIS)as a multi-functional electrolyte additive for H2O/HF scavenging and film formation to improve the high temperature performance of LiNi_(0.8)Co_(0.1)Mn_(0.1)O_(2)/graphite *** 450 cycles at room temperature(25℃),the discharge capacity retentions of batteries with blank and PHIS-containing electrolyte are 56.03%and 94.92%*** 230 cycles at high temperatures(45℃),their values are 75.30%and 88.38%*** enhanced electrochemical performance of the batteries with PHIS-containing electrolyte is supported by the spectroscopic characterization and theoretical *** is demonstrated that this PHIS electrolyte additive can facilitate the construction of the electrode interface films,remove the H2O/HF in the electrolyte,and improve the electrochemical performance of the *** work not only develops a sulfonate-based electrolyte but also can stimulate new ideas of functional additives to improve the battery performance.
