1. Ibicuruzwa byingenzi
Ibikoresho byibanze bya Graphite Anode ni ibikoresho byifu byateguwe byateguwe nuburyo busobanutse nka pre - carboneisation, kumenagura, kweza, no gutondekanya amanota, hamwe na - coke y'urushinge rwera, kokiya ya peteroli, cyangwa amakara - ashingiye kuri kokiya. Nibintu byingenzi bibanziriza umusaruro wa artite grafite ya electrode mbi ya bateri ya lithium. Agaciro kayo kingenzi ni ugutanga ubuziranenge - bwo gutunganya ibishushanyo mbonera nyuma yo gutunganya ibishushanyo mbonera binyuze mu kugenzura neza imiterere y’imiti n’imiterere y’umubiri, amaherezo bigaha gradite artificiel electrode ifite imbaraga nziza, gutwara amagare, hamwe n’imikorere y’ibipimo, byujuje ibyangombwa bisabwa na bateri ya lithium kugirango "ubushobozi buke, ubuzima burebure, n'umutekano muke".

3.Ibiranga Ibicuruzwa
(1) Ibirimo byinshi bya karubone hamwe n’umwanda muke
Ibikoresho bya karubone bihamye Birenze cyangwa bingana na 98.5% (hejuru - ibyiciro by’ingufu zanyuma birarenze cyangwa bingana na 99.5%), ibivu by ivu Bitarenze cyangwa bingana na 0.3% (ibirimo byose byanduye byuma nka Fe, Ni, Cu Bitarenze cyangwa bingana na 50ppm), ibirimo bya sulferi Ntibiri cyangwa bingana na 0.1%, azote iri munsi cyangwa ihwanye na 0.2%; Umwanda muke uranga urashobora kwirinda kwitwara kuruhande mugihe cyamagare ya batiri, kugabanya kwangirika kwa electrolyte, no kwemeza ituze rya interineti mbi.
(2) Optimized Particle Morphology na Particle Ingano Ikwirakwizwa
Kubikoresho Byibanze bya Graphite Anode, ibice bifite imiterere cyangwa imiterere idasanzwe, bifite ubuso bworoshye kandi nta mpande zityaye (kugirango wirinde gukuramo substrate mugihe cyo gutwikira electrode); ingano yubunini bwayo ikwirakwizwa (D 50=10-50 μm, Span =0.8-1.2), kandi irashobora guhindurwa ukurikije ubunini bwibisabwa byapa ya electrode mbi. Irakwiriye kubikorwa byumusaruro hamwe nubucucike butandukanye (1.6-1.8g / cm³) kugirango utezimbere icyapa cya electrode.
(3) Imikorere myiza ya Graphitisation
Hariho amahirwe menshi yo kuzamura impamyabumenyi. Nyuma yubushyuhe bwo hejuru - ubushyuhe bwa dogere 2800-3000, impamyabumenyi ya grafite irashobora kugera hejuru ya 90%, naho guhoraho kwa lattice (c0) ni munsi cyangwa ihwanye na 0.3356nm; Mugihe cyo gushushanya, igipimo cyo kugabanuka kwijwi gikomeza kuba gihamye (Ntibisanzwe cyangwa bingana na 5%), bishobora kugabanya ibyago byo guturika mubicuruzwa bibi bya electrode kandi bikagabanya igihombo cyumusaruro.
(4) Uburyo bwiza bwo guhuza n'imihindagurikire
Ifu ifite umuvuduko mwiza (inguni ya repose Ntibisanzwe cyangwa bingana na dogere 38) kandi byoroshye kuvangwa kimwe hamwe na binders (nka PVDF) kugirango bibe sisitemu ihamye; Mugihe cyo guhuzagurika, ifite plastike ikomeye kandi ntabwo ikunda kumeneka ibice, byemeza imiterere ya electrode kandi ihuza n'imirongo ikora neza.
4. Ibice byingenzi byo gusaba
(1) Amashanyarazi ya Litiyumu
Ikoreshwa mugukora ibishushanyo mbonera bya grafitike ya electrode ya bateri nshya yingufu zamashanyarazi, hamwe nubushobozi buhanitse kandi buranga polarisiyasi nkeya, itezimbere igipimo cyumuriro wa batiri no gusohora (gushyigikira byihuse 1C-3C), mugihe itanga ubuzima bwikubye inshuro zirenga 2000, byujuje ibyifuzo byimodoka nubuzima bwa serivisi.
(2) Ububiko bw'ingufu za Batiri ya Litiyumu
Bikwiranye na batiri ya lithium electrode mbi mububiko bwingufu zibika ingufu (nka Photovoltaque nuyumuyaga ushyigikira ububiko bwingufu), ibirimo umwanda muke birashobora kugabanya igipimo cya batiri - gusohora (buri kwezi - gusohora munsi cyangwa bingana na 3%), kandi imikorere ihamye ituma ubushobozi buke bwangirika bwa bateri mugihe kirekire -.
(3) Umuguzi wa Electronics Litiyumu Bateri
Ikoreshwa nka electrode itari nziza kuri bateri ya lithium mubikoresho bya elegitoroniki byabaguzi nka terefone zigendanwa na mudasobwa zigendanwa, gukwirakwiza ingano y’ibice byabigenewe bishobora kugera ku kunanuka kwa electrode (umubyimba wa electrode munsi cyangwa ingana na 80μm) kandi igateza imbere ingufu za bateri (hamwe na - ubushobozi bwa electrode nziza cyane, irashobora kugera kuri 4.5Wh / cm³).
(4) Umwanya wa Batiri ya Litiyumu idasanzwe
Ikoreshwa nka electrode itari nziza kuri bateri ya lithium ahantu harehare - ahantu h’ubushyuhe (nkibikoresho bigenzura inganda) cyangwa ubushyuhe buke - ibidukikije (nkibikoresho byo hanze), bateri ikomeza imikorere ihamye yo gusohora (igipimo cyo kugumana ubushobozi Birenze cyangwa bingana na 80%) kuri dogere -20 dogere -60 mukugena ibirimo umwanda hamwe nimpamyabumenyi.
Ibirangantego: ibikoresho fatizo bya anode ya artite, Ubushinwa ibikoresho fatizo kubukorikori bwa grafite
