"Intebe" ya koke ya peteroli ya grafitis ntabwo ishobora gusenywa n'ibikomoka kuri graphene cyangwa grafiti y'ubukorano mu gihe gito, ariko ishobora guhura n'imbogamizi zikomoka ku ivugurura ry'ikoranabuhanga no kuvugurura uruhererekane rw'inganda mu gihe kirekire. Isesengura rikurikira rikorwa mu buryo butatu: imiterere y'ibikoresho, ikoreshwa ry'ibintu, n'imigendekere y'uruhererekane rw'inganda.
I. Umwanya w'ingenzi wa Koke ya Peteroli ifite Graphitized: Inzitizi ebyiri z'ikiguzi n'uburyo ikorwa
Ibiranga ibikoresho fatizo bidasimburwa
Koke ya peteroli ya grafitize ni yo ikoreshwa cyane mu gukora ibikoresho bya anode ya bateri ya lithiamu-ion, hamwe n'inyungu zirimo:
- Kunoza Ikiguzi: Gukora toni 1 ya grafiti y'ubukorano bisaba toni 1.2–1.5 za coke ya peteroli. Hashingiwe ku giciro gito cya coke ya peteroli ya yuan 6.000 kuri toni mu 2025, ikiguzi cy'ibikoresho fatizo kingana na 36%–45% by'ikiguzi cyose cya grafiti y'ubukorano (hafi yuan 25.000 kuri toni). Guhindura ibikoresho bisimbura ibindi byakongera cyane ikiguzi.
- Gukura kw'Ibikorwa: Nyuma yo gutunganya graphite kuri 2,500–3,000°C, peteroli coke ikora imiterere ya kristale ya grafiti, itanga amashanyarazi meza cyane n'ubushyuhe buhamye—ni ingenzi ku mikorere ya graphite y'ubukorano.
Imbogamizi zikomeye ku ruhererekane rw'ibicuruzwa
- Imbogamizi z'umusaruro: Mu 2025, umusaruro wose wa peteroli mu Bushinwa ni toni miliyoni 29, aho coke ifite sulfure nke (ingano ya sulfure <3%) ingana na 30% (hafi toni miliyoni 8.7). Ibi bigomba guhaza ibyifuzo bya anode za aluminium zitetse mbere, electrode za grafiti z'icyuma, n'ibikoresho bya anode, bigatuma habaho ubwisanzure buke mu gutanga.
- Igenzura ry’ibyoherezwa mu mahanga: Mu 2025, Ubushinwa bwashyizeho amategeko agenga ibyoherezwa mu mahanga ku bikoresho bya anode ya grafiti n’ibindi bikoresho bifitanye isano, bituma inganda zikora bateri zo mu mahanga zihutisha iterambere ry’uruhererekane rw’ibicuruzwa mu gihugu, birushaho kongera ikenerwa rya coke ya peteroli ifite sulfure nke.
II. Abahanganye: Imbogamizi z'ibikomoka kuri Graphene na Graphite karemano
Ibicuruzwa bya Graphene: Inzitizi ku ikoranabuhanga n'ibiciro
- Umusaruro muke: Ibikomoka ku gukora graphene (urugero, graphene nanoribhoni, dots za quantum) biguma mu ikoreshwa rya laboratwari cyangwa mu bunini, ntibishobora gusimbuza peteroli coke ku rugero runini.
- Ingaruka mbi ku giciro: Urugero, ikoranabuhanga rya "flash" rya Kaminuza ya Rice risaba kugurisha ibikomoka kuri graphene ku giciro cya 5% by'ibiciro ku isoko kugira ngo harebwe ikiguzi cyo gukora hydrogen, bigaragaza ko nta bukungu buhagije bushobora gukoreshwa mu nganda.
Graphite karemano: Kugereranya imikorere n'ikiguzi
- Imbogamizi mu mikorere: Nubwo grafiti karemano igura 30% munsi ya grafiti y’ubukorano, imiterere yayo ya kristu iteye imbere itera anisotropy, bigatuma ubuzima bw’uruziga budakora neza ndetse n’ubushobozi bwo gukora neza ugereranije na grafiti y’ubukorano. Urugero, grafiti karemano isanzwe ikoresha uruziga ruri munsi ya 1.500, mu gihe grafiti y’ubukorano irenga uruziga 2.000.
- Impinduka mu ikoranabuhanga: Guhindura irangi ryo hejuru (urugero, nano-silicon carbide layers) bishobora kongera igihe cyo gukora grafiti karemano kirenga 2.000, ariko gutunganya byiyongereyeho byongera ibiciro, bigakuraho inyungu ku biciro.
III. Impinduka z'igihe kirekire: Ivugurura ry'ikoranabuhanga n'ivugurura ry'uruhererekane rw'inganda
Ingaruka z'ikoranabuhanga rya Anode y'ikinyejana gikurikira
- Anode zishingiye kuri Silicon: Zifite ubushobozi bwa teorike bwa 4.200 mAh/g (inshuro 10 ugereranyije na graphite), anode zishingiye kuri silicon zishobora guhangana n'umuvuduko w'ikiguzi cya peteroli. Isoko ryazo ryazamutse kuva kuri 5% rigera kuri 15% mu 2025, ariko kwiyongera k'ingano (>300%) mu gihe cyo gutwara igare biracyari ikibazo gikomeye mu kwangirika k'ubuzima bw'igare.
- Ibikoresho bya Karuboni Ikomeye: Karuboni ikomeye ya GAC Aion ikomoka kuri biomass (ishingiye ku gishishwa cya kokonati) ikwiranye na bateri za sodium-ion, aho ibikoresho fatizo bigura kimwe cya gatatu cy’ibicuruzwa bya peteroli bya coke. Ariko, ubucucike bwayo bw’ingufu nke (~300 mAh/g ugereranyije na 372 mAh/g ya grafiti) bugabanya ubushobozi bwo gusimbuza mu gihe gito.
Irushanwa ryo guhuza no guhatana mu buryo burambuye mu ruhererekane rw'inganda
- Upstream Lock-In: Inganda zikomeye zo mu gihugu zikora anode zicunga koke idafite sulfur nyinshi binyuze mu kugura imigabane mu nganda zitunganya cyangwa mu mashanyarazi. Urugero, CATL yagabanyije kwishingikiriza kuri koke ikoresha peteroli binyuze mu gukoresha uburyo buhoraho bwo gushushanya kugira ngo igabanye imikorere y’umusaruro.
- Amashyirahamwe Mpuzamahanga: Ibigo bikomeye bya batiri mu mahanga (urugero: Samsung SDI, LG Energy Solution) byagiranye ubufatanye n'ibigo by'ubutasi bw'ibikomoka kuri peteroli byo mu Bushinwa, bihana ishoramari kugira ngo babone umutungo wo kubona ibikoresho mu myaka icumi iri imbere.
Umwanzuro: Guhagarara mu gihe gito, Kwitonda mu gihe kirekire mu kwirinda gusimbuza abandi
Ingufu za peteroli zikoresha graphitized coke ziracyari zikomeye mu gihe gito, zishingiye ku nyungu z'ikiguzi, igihe cyo gukora, no gukomera kw'uruhererekane rw'ibicuruzwa. Ariko, mu gihe kirekire, ubucuruzi bw'ikoranabuhanga rigezweho nka anode zishingiye kuri silicon na karuboni ikomeye, hamwe n'ipiganwa ry'umutungo uva mu guhuza imiterere, bishobora kugabanya ubushobozi bwayo buhoro buhoro. Abafatanyabikorwa mu nganda bagomba gushyira imbere:
- Iterambere ry'ikoranabuhanga: Kwihutisha kunoza imikorere no kugabanya ikiguzi cya anode zishingiye kuri silikoni, karuboni ikomeye, n'izindi nzira.
- Ingamba z'umutungo: Gucunga imiyoboro y'ibicuruzwa binyuze mu bufatanye mu nganda zitunganya ibikomoka ku bimera cyangwa ibindi bikoresho fatizo (urugero, biomass coke).
- Guhindura Politiki: Guhindura uburyo bwo kuvugurura uruhererekane rw'ibicuruzwa ku isi hifashishijwe uburyo bwo kugenzura ibicuruzwa byoherezwa mu mahanga, binyuze mu kwagura ubushobozi bw'ibicuruzwa byo mu mahanga.
