Abaphandi kwiSebe leMigangatho ye-US (DoE) elebhu ye-Argonne i-Argonne inembali ende yobuvulindlela obufunyenwe yintsimi yeLithium yeLithium-ion. Uninzi lwezi ziphumo zezokubhekiswa kwebhetri, ebizwa ngokuba yi-NMC, iNickel Manganese kunye neCobalt Oxide. Ibhetri malunga le thehode ngoku inamandla i-chevrolet bolt.
Abaphandi be-argonne baphumelele olunye ubhukuqwa kwi-NMC CASODS. Isakhiwo esitsha se-cathode esincinci se-Cathode sinokwenza ibhetri ingakumbi kwaye ikhuseleke, iyakwazi ukusebenza kwii-voltures eziphakamileyo kakhulu kwaye zibonelela ngeendlela ezinde.
"Ngoku sinesikhokelo sokuba abavelisi beebhetri anokuyisebenzisa ukwenza uxinzelelo oluphezulu, iArgonne Bedmatimumu.
"I-NMC ye-NMC ye-NMCODS EVELDES EYA KUKHONA UMSEBENZI WOKUGQIBELA WOKUGQIBELA," utshilo uCimist Wimist Geliang Xu. Ngomdla wokugqibela wokuhamba ngebhayisikile, ukusebenza kwehla ngokukhawuleza ngenxa yokuqulunqa ii-rocks kumasuntswana amaKathode. Kumashumi eminyaka, abaphandi bebhetri babefuna iindlela zokulungisa ezi mpahla.
Enye indlela kwixesha elidlulileyo elisebenzisa amasuntswana amancinci aqaqanjiweyo odityaniswe ngamasuntswana amancinci amaninzi. Amasuntswana amakhulu e-sloherical i-polycrystalline, kunye ne-crystalline sceides yearhente ezahlukeneyo. Ngenxa yoko, banokuthetha izinto zesayensi ezibiza imida phakathi kwamasuntswana, enokubangela ibhetri ukuba iqhekeke ngexesha lomjikelo. Ukuthintela oku, amaQu kunye noLogqwetha ka-Argonne bebekhe bakhulisa i-polymer ekhuselayo i-parlymer ejikelezayo ejikeleze i-surlyment nganye. Oku kudibana kujikeleza amasuntswana amakhulu kunye namasuntswana amancinci ngaphakathi kubo.
Enye indlela yokuphepha olu hlobo lokuqhekeka kukusebenzisa amathafa anye. I-elektroscopy ye-elektroni yala masuntswana ibonise ukuba azinamida.
Ingxaki yeqela yayikukuba amaKathodes owenziwe ngeepolycrystals ezinamakhonkco kunye neekristale ezizodwa zisaqhekekile ngexesha lokuhamba ngebhayisikile. Ke ngoko, baqhuba uhlalutyo olubanzi lwezi zinto zasebukhosini kumthombo we-Photon we-Photon
Uhlalutyo olwahlukeneyo lwe-X-Ray lwenziwa kwiingalo ezintlanu ze-APs (11-BM, 20-I-2-ID-D, I-ID-C kunye ne-34-ID-E). Kuyabonakala ukuba le nto icinga ngayo yayiyinto eyongeziweyo, njengoko kubonisiwe kwi-elektroni kunye ne-ray microscopy, eneneni yayinomda ngaphakathi. Ukuskena kunye ne-elektroni ye-elektroni yemicroscopy yee-CNMS kuyiqinisekisa esi sigqibo.
"Xa sijonga i-morphology yala masuntswana, babekhangeleka ngathi amakristali enye," watsho uWonjun Liu. â� <"但是, 但是 APs 使用一种称为同步加速器 x 射线衍射显微镜的技术和其他技术时, 我们发现边界隐藏在内部." â� <"但是, 当 在 在 使用 使用 使用 称为 称为 同步 显微镜 显微镜 的 技术 技术 和 其他 其他 其他 时 时 时 时 时 时 时 隐藏 隐藏 隐藏 在.""Nangona kunjalo, xa sasisebenzisa ubuchule esibizwa ngokuba yi-Synchrotron X-Ranchratcopy microscopy kunye nezinye iindlela kwii-APs, safumanisa ukuba imida ifihlwe."
Ngokubalulekileyo, iqela liphuhlise indlela yokuvelisa i-crystals enye ngaphandle kwemida. Ukuvavanya iiseli ezincinci kunye ne-Crystal ye-Crystade ye-Crystade kwi-intanethi kakhulu kudala i-25% yonyuso lwamandla kwicandelo ngalinye ngaphandle kokulahleka kwi-100 yeendlela zokusebenza. Ngokwahlukileyo, i-nuckade ye-NMC iqashelwe iikristali ezahlukeneyo zohlobo oluninzi okanye iipolycrystals ezinamathanga abonisa amandla angama-60% ukuya kwi-88% ngaphezulu kwexesha elifanayo.
Ukubala kwesikali seatomic kutyhila indlela yokupheliswa kwe-cathode. NgokukaMaria chang, i-nanosleest kwi-CNM, imida inokwenzeka ukuba ilahlekelwe ziiathom zeoksijini xa ibhetri ihlawuliswa ngaphezu kwazo. Le ilahleko yeoksijini ikhokelela ekuthambekeni komjikelo weseli.
"Ukubala kwethu kubonisa ukuba umda ungakhokelela njani kwioksijini ekhutshwe kwingcinezelo ephezulu, enokukhokelela ekunciphiseni ukusebenza, i-chan yatsho.
Ukuphelisa umda uthintela i-oxygen iveralution, ngaloo ndlela iphucule ukhuseleko nokuzimela kwe-cyccicy ye-canode. Imilinganiselo ye-OXYGENT EVISILLYO enee-APs kunye nomthombo wokukhanya okhethekileyo kwi-US yeSebe leLabhorey lase-US Gorgy Berrence Berrence Berrence Berrence Berrence Gearchy uqinisekise esi sigqibo.
"Ngoku sinezikhokelo abanokuzisebenzisa abavelisi beebhetri ukwenza izinto ezingekho mthethweni ezingenamida kwaye zisebenza kwingcinezelo ephezulu," watsho uKhalil Amin, ama-Argonne Tomters. â� <"该指南应适用于 NMC 以外的其他正极材料." â� <"该指南应适用于 NMC 以外的其他正极材料.""Izikhokelo kufuneka zisebenze kwizixhobo ze-canode ngaphandle kwe-NMC."

ISebe le-US lezemithombo ye-US ye-US Ii-APs zibonelela nge-X-rays ephezulu yophando kuluntu oluqhelekileyo kwiSayensi yeZandla, i-chemistry, i-firsists, ubomi kunye neSayensi yezeNdalo, kwaye yafaka uphando. Ezi x-ray zilungele ukufunda izixhobo kunye nezixhobo zebhayoloji, ukusasazwa kwezinto, iikhemikhali, ii-ofisi ezizezobunjineli, kunye nezobuchwephesha bezobunjineli, kunye nezobuchwephesha kwezoqoqosho, ezibalulekileyo kuqoqosho lwethu lukazwelonke, itekhnoloji. kunye nomzimba wesiseko sempilo. Nyaka ngamnye, bangaphezulu kwe-5000 abaphandi basebenzisa ii-APs ukupapasha iimpapasho ezingaphezu kwama-2 000 ezibonisa izinto ezifunyanisiweyo zebhayoloji ezibaluleke kakhulu kunazo naziphi na iziko labasebenzisi be-X-ray. Izazinzulu ze-APs kunye neenjineli zisebenzisa itekhnoloji enobuchule esisiseko sokuphucula ukusebenza kwabakhalikhali kunye nemithombo yokukhanya. Oku kubandakanya izixhobo zokufaka ezivelisa i-X-rays eziqaqambileyo ze-X ezixineneyo ngabaphandi, iilensi ezigxile kwi-Nanomester ephantsi kwe-X-rays zinxibelelane nendlela yokufumana uvavanyo, kunye nolawulo lwe-APS efunyenweyo.
