A thorough analysis of the evolution of the voltage profiles of silicon nanoparticle electrodes upon cycling has been conducted. The largest changes to the voltage profiles occur at the earlier stages ( > 0.16 V vs Li/Li + ) of lithiation of the silicon nanoparticles. The changes in the voltage profiles suggest that the predominant failure mechanism of the silicon electrode is related to incomplete delithiationofthesiliconelectrodeduringcycling.Theincompletedelithiationisattributedtoresistanceincreasesduringdelithiation,whicharepredominantlycontactandsolidelectrolyteinterface(SEI)resistance.Thecapacityretentioncanbesignificantlyimprovedbyloweringdelithiationcutoffvoltageorbyintroducingelectrolyteadditives,whichgenerateasuperiorSEI.TheimprovedcapacityretentionisattributedtothereductionofthecontactandSEIresistance.©TheAuthor(s)2015.PublishedbyECS.ThisisanopenaccessarticledistributedunderthetermsoftheCreativeCommonsAttribution4.0License(CCBY,http://creativecommons.org/licenses/by/4.0/),whichpermitsunrestrictedreuseoftheworkinanymedium,providedtheoriginalworkisproperlycited.[DOI:10.1149/2.0731512jes]Allrightsreserved.
