LiNixMnyc._(z)O_(2)(x≥0.8)(NMc.partic.es with poly(3,4-ethylenedioxythiophene)(PEDOT).The simulation results show that the c.ating of.primary NMc.partic.es signif.c.ntly reduc.s the stress generation by ef.ic.ently ac.ommodating the volume c.ange assoc.1}ted with the lithium dif.usion,and the c.ating layer plays roles both as a c.shion against the volume c.ange and a c.annel f.r the lithium transport,promoting the lithium distribution ac.oss the sec.ndary partic.es more ***,the lower stif.ness,higher ionic.c.nduc.ivity,and larger thic.ness of.the c.ating layer improve the stress *** paper provides a mathematic.l f.amework f.r c.lc.lating the c.emo-mec.anic.l responses of.anisotropic.elec.rode materials and f.ndamental insights into how the c.ating of.NMc.ac.ive partic.es mitigates stress levels.
