英文摘要	5 V lithium ion batteries (LIBs) are promising candidates for high energy density batteries. However, conventional carbonate-based liquid electrolyte is vulnerable to oxidative decomposition caused by free radical attack, which leads to poor cycling performance of the 5 V LIBs. Herein, we present a novel strategy based on the free radical scavenging effect to suppress the electrolyte decomposition of 5 V class batteries composed of LiNi 0.5 Mn 1.5 O 4 (LNMO) cathodes and carbonate-based electrolyte. Our strategy is to scavenge the free radicals during the charging process at the cathode interface by adopting a renewable biomass lignin binder with numerous phenol groups, which can significantly suppress the free radical chain reaction and subsequently generate a compatible multi-dimensional interphase between the electrode and electrolyte. The lignin based electrode exhibited a capacity retention of 94.1% after 1000 cycles, which is significantly higher than that of its PVDF counterpart (46.2%). This work represents a milestone contribution to the strategy for resolving the interfacial issue of high voltage cathode materials, initiating a big step in boosting 5 V batteries. © 2019 The Royal Society of Chemistry.
