摘要 In the past decade,the surging demand for portable electronics,electric vehicles,and stationary energy storage grids has triggered a noticeable rise in the production of Li-ion batteries(LIBs).However,this swift rise is now hindered by relying on the use of N-methyl-2-pyrrolidone(NMP),a repro-toxic solvent,in the current cathode processing of LIBs.To overcome this challenge,here we have investigated triethyl phosphate(TEP) as a greener alternative to NMP.The compatibility with polyvinylidene fluoride(PVDF)binder,the slurry rheology,the electrode morphology and cell performance with Ni-rich cathodes are characterized.The results show that TEP-based samples possess indistinguishable characteristics in all as pects studied when compared with NMP,revealing that TEP is a promising substitute for NMP in processing Ni-rich cathodes.It is anticipated that this green solvent,TEP,will draw attention from industry in the real-world LIB application in the future.
