Ofufuzawo ku Dipatimenti ya US ya US (Doe) la National Labotale ali ndi mbiri yayitali yopenda upainiya pantchito ya mabatire a lithiamu-ion. Zotsatira zake zambiri ndi za catavice Cavide, yotchedwa nmc, nickel manganese ndi coble oxide. Batri ndi cakatode iyi tsopano mphamvu ya Chevrolet Bolt.
Ofufuza a Argonne apezanso chitsime china mu NMC Cancedes. Tizilombo tating'ono tating'ono tating'ono timene titakhala nditakhala cholimba komanso zotetezeka, zimatha kugwira magetsi kwambiri komanso zimapereka maulendo atatali.
"Tsopano tili ndi chitsogozo kuti opanga Batri angagwiritse ntchito kupanga zinthu zazitali," khalil Amin, mnzake.
"NMC ya NMC yomwe ilipo idapereka zovuta zazikulu za magetsi pantchito zapamwamba," adatero wothandizira wa mankhwalawa guiliang xu. Ndi njinga zochotsa milandu, magwiridwe antchito amatsika mwachangu chifukwa cha mapangidwe ming'alu mu catoko. Kwa zaka makumi ambiri, ofufuza batry ayang'ana njira zokonza ming'aluyi.
Njira imodzi m'mbuyomu idagwiritsa ntchito tinthu tating'ono tating'ono tomwe timapangidwa ndi tinthu tating'onoting'ono tambiri. Tizikulu zigawo zazikulu ndi polycrystalline, ndi madera a makhirstalline amaizoni osiyanasiyana. Zotsatira zake, ali ndi zomwe asayansi amatcha malire a tirigu pakati pa tinthu tating'onoting'ono, zomwe zingapangitse batiri kuti lisatane pa kuzungulira. Popewa izi, anzanu a argonne anali atapanga kale zoteteza poyimitsa tinthu tokha. Kuphimba uku kumazungulira tinthu tambiri ndi tinthu tating'onoting'ono mkati mwawo.
Njira ina yopewera mtundu uwu wosweka ndikugwiritsa ntchito tinthu tating'onoting'ono. Ma millioncomcopy a tizinthu izi adawonetsa kuti alibe malire.
Vuto la gululi linali lakatolika lomwe limapangidwa kuchokera ku ma polycrystals obiriwira ndi makristalo amodzi omwe adasokonekera pakuyenda njinga. Chifukwa chake, adawunikira kwambiri zida za Canceode iyi pa Shope Yotsogola (APS) ndi Center ku Nanomatadium (CNM) ku Deadment of Ergonne Stute Center Center.
Kusanthula kosiyanasiyana kwa X-ray kunachitidwa pa mikono isanu (11-BM, 20-BM, 2-ID-5). Zimapezeka kuti zomwe asayansi amaganiza kuti chinali mawonekedwe amodzi, monga momwe akuwonetsera ndi electron ndi ray Microscopy, anali ndi malire mkati. Kusakanizira ndi kufalitsa mafoni a ma cnms a ma CMS adatsimikizira izi.
"Titayang'ana pansi morphology ya tinthu tating'onoting'ono, zimawoneka ngati makristali amodzi," anatero a Statusst Wenjun LIU. Â� <"<, 当我们在 APS 使用一种称为同步加速器 X 射 射 的 技术和其他技术时, 我们发现边界隐藏在内部." â� <""Komabe, tikamagwiritsa ntchito njira yotchedwa Syntrotron X-ray Cliquopy ndi njira zina ku APS, tidawona kuti malirewo adabisidwa mkati."
Chofunika, gululi lapanga njira yopangira makhiristo amodzi osapita malire. Kuyesa maselo ang'onoang'ono ndi castrist unyinjiwu kwa ma volipi ambiri omwe adawonetsa kuchuluka kwa 25% pakusungidwa kwa mphamvu pa unit muyeso ndi kusowa kwa magwiridwe antchito oposa 100 mayeso. Mosiyana ndi izi, NMC Catodes yopangidwa ndi masikono angapo kapena ma polycrystals obiriwira adawonetsa kutsika kwa 60% mpaka 88% pamoyo womwewo.
Kuwerengera kwa atomiki kumawonetsa makina a Cast Caviode Cance. Malinga ndi a Mariang, katswiri wa Nanosical ku CNM, malire amatha kutaya maatomu a mpweyawo pamene batri itaperekedwa kuposa madera ena kutali ndi iwo. Kutayika kwa mpweyawo kumabweretsa kuwonongeka kwa maselo.
"Kuwerenga kwathu kuwonetsa momwe malire angachitire kwa oxygen akumasulidwa kukulumizidwa kwambiri, komwe kumatha kuchititsa kuti athetse ntchito," chan anati.
Kuchotsa malire kumalepheretsa chisinthiko, potero kumapititsa patsogolo chitetezo ndi kukhazikika kwa cyclic ku Castde. Kuyimiritsa kwa Exygen ndi Aps ndi gwero lowunikira kwambiri ku Dipatimenti ya US ya Lawn Berkeley Labout Labotale la Inckeley kutsimikizira izi.
"Tsopano tili ndi malangizo omwe wopanga batri angagwiritse ntchito kupanga camtope zida zomwe zimakhala ndi malire ndikugwira ntchito yovuta kwambiri," adatero Khalil Amin, mnzake ku Argonne. Â� <"<nmc 以外 的 其他正极材料." Â� <"<nmc 以外 的 其他正极材料.""Malangizo azigwira ntchito ku Carviode zida kupatula NMC."
