Ni izihe ngamba n'uburyo bwo kunoza imikorere ya peteroli coke ifite graphitized?

Kugira ngo habeho ibyifuzo bya bateri za lithium-ion zo mu gisekuru gitaha zifite imikorere myiza, coke ya peteroli ifite graphite isaba kunoza imikorere y’umuvuduko, kudahindagurika kw’ingendo, imikorere y’ubushyuhe buke, imbaraga z’imiterere, imikorere y’ibanze, no kugabanya ikiguzi mu bijyanye n’imikorere y’umusaruro. Isesengura ryihariye ni iri rikurikira:

I. Kongera imikorere y'igipimo n'ihindagurika ry'ingendo

Ikibazo: Mu gihe cyo gutanga no gusohora umuriro, gushyira no gukuramo iyoni za lithiyumu muri koke ya peteroli ya grafiti bishobora gutuma ibice bya grafiti byaguka kandi bigacika. Mu gihe kirekire, ibi bishobora kwangiza imiterere y'umubiri, bigahindura imiterere y'uruziga. Amabwiriza yo kunoza:

• Gutunganya Imiterere y'Ibice: Hitamo ibikoresho bya mbere bya sisitemu bya coke kandi ukoreshe ibikoresho byoroshye gukoresha graphitize nka pitch nk'isoko ya karuboni ku bikoresho bifatanya. Mu gutunganya ibi bikoresho mu itanura rizunguruka, ibice byinshi bya sisitemu bya coke bishobora guhuzwa hamwe kugira ngo bikore ibice bya kabiri bifite ingano ikwiye y'ibice, hanyuma hagakurikiraho graphitize. Ubu buryo bugabanya neza igipimo cy'icyerekezo cya crystallite (agaciro ka OI) cy'ibikoresho kandi bukongera inzira yo gukwirakwiza iyoni za lithiamu, bityo bikanoza imikorere y'igipimo.
• Guhindura Ingufu zo Kuraho: Koke ya peteroli ikoze muri graphite ikoresheje ibikoresho nka karubone idafite imvange, okiside z'icyuma, cyangwa polymer kugira ngo hubakwe uduce tw’imiterere y’ “inkingi y’ibumba”. Urusobe rw’ingufu rushobora gutandukanya imikorere ya electrolyte, kugabanya ahantu hakora ku buso, kugabanya ubuso bwihariye, no kongera ubushobozi bwo gushyira no gukwirakwiza iyoni za lithiamu, bityo bikanoza uburyo uruziga ruhagaze.

II. Kongera imikorere y'ubushyuhe buri hasi

Ikibazo: Mu bidukikije bifite ubushyuhe buke, igipimo cyo gukwirakwira kwa iyoni za lithiamu muri koke ya peteroli ikozwe muri grafiti kigabanuka, bigatuma imikorere ya bateri igabanuka. Amabwiriza yo kunoza:

• Gukoresha Soft Carbon: Gushyiramo igice runaka cya soft carbon muri graphite anode bishobora kunoza imikorere ya bateri mu gihe cyo gusharija ubushyuhe buke. Soft Carbon ifite imiterere idahinduka ifite intera nini hagati y’ibice kandi ihura neza na electrolyte, bigatuma ikora neza mu gihe cyo buke. Ariko, ikigereranyo cya doping kigomba kugenzurwa neza kugira ngo gihuze imikorere y’ubushyuhe buke n’igihe cyo kuzenguruka.
• Kunoza Uburyo bwo Gutunganya Electrolyte: Kunoza uburyo bwo gutunganya electrolyte wongeramo inyongera nshya cyangwa guhindura imiterere y'ibinyabutabire kugira ngo ugabanye ubushyuhe bwa electrolyte mu bushyuhe buke kandi wongere umuvuduko wo gukwirakwiza kwa iyoni za lithiamu.

III. Kunoza imbaraga n'ubudahangarwa by'inyubako

Ikibazo: Ibikoresho bya karuboni bifite grafiti nyinshi, nubwo bifite ubushobozi bwo hejuru n'ibikoresho bitanga umuriro bidahindagurika, bishobora kugaragaza imikorere mibi mu ngendo no mu bushyuhe buke. Amabwiriza yo kunoza:

• Kugenzura Ingano ya Graphitization: Mu gihe cyo gukora graphitization, urwego rwa graphitization rugomba kugenzurwa kugira ngo hagumane imiterere imwe n'imwe idahinduka hagati ya microcrystals, bityo hagakomeza urwego runaka rw'imbaraga z'imiterere.
• Gushyira ahagaragara Nanostructures: Mu kubaka nanostructures cyangwa imiterere ifite imyenge, umubare w'imiyoboro yo gushyiramo no gukuramo iyoni za lithium ushobora kwiyongera, bigatuma imiterere y'ibikoresho ikomera.

IV. Kunoza Imikorere y'Imbere no Kugabanya Ikiguzi

Ikibazo: Nk'ibikoresho bya anode, coke ya peteroli ya grafiti ishobora kugaragaza umusaruro muke mu ntangiriro ndetse n'ikiguzi cyo kuyikora kiri hejuru. Amabwiriza yo kunoza:

• Uburyo bwo kuvura ogisijeni ku butaka: Shyira umuti ukomeye wo gusiga ogisijeni kuri peteroli ukoresheje umuti wo gusiga ogisijeni kugira ngo ogisijeni kandi utume ubushobozi bwo gukora ku butaka buhagarara kandi bugabanye imikorere y’amatsinda, bityo urusheho kunoza imikorere y’ibanze.
• Kunoza Imikorere y'Umusaruro: Kunoza Imikorere y'Umusaruro nko Gutunganya Kalisiyumu na Graphitisation kugira ngo bigabanye ikiguzi cy'Umusaruro no kunoza Imikorere.
