Currently　known　organic　electrode　materials　for　lithium-ion　batteries　have　severe　cost　and　resource　constraints　and　are　difficult　to　implement　in　applications　for　large-scale　electrical　energy　storage.　Compared　to　lithium-ion　battery　electrode　materials,　sodium-ion　battery　electrode　materials　are　more　abundant　and　more　cost　effective.　However,　methods　for　the　prediction　of　organic　electrode　materials　for　sodium-ion　batteries　are　not　perfect　at　present.　A　fast　and　accurate　theoretical　method　for　finding　possible　candidates　for　organic　electrode　materials　for　Na-ion　batteries　is　urgently　needed.　In　the　present　work,　dispersion-corrected　hybrid　density　functional　theory　is　applied　to　study　five　organic　electrode　materials　for　Na-ion　batteries.　The　results　of　this　study　show　that　the　D2　dispersion-corrected　hybrid　functional　method　(HSE06-D2)　can　precisely　calculate　the　potential　of　organic　materials　with　a　small　average　error　of　approximately　3.68%.　The　band　gap　values　are　approximately　lower　than　2.5　eV,　which　proves　that　the　materials　have　good　conductivity　and　are　expected　to　be　candidates　for　organic　electrode　materials　for　sodium-ion　batteries.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
