Uturemangingo twa lithiyumu two mu rwego rwa B, izwi kandi nkauturemangingo tw'amashanyarazi ya lithium twongeye gukoreshwa, bagumana 60-80% by'ubushobozi bwabo bw'umwimerere kandi ni ingenzi mu kuzenguruka kw'umutungo ariko bahura n'imbogamizi zikomeye. Mu gihe bongera kubikoresha muriububiko bw'ingufucyangwa kugarura ibyuma byabyo bigira uruhare mu kurambye, hafi 70% by'izi selile za lithium zakoreshejwe mu Bushinwa zinjira mu bigo bitemewe n'amategeko. Ibi bigabanya imikorere kandi bigateza akaga ku mutekano w'ibidukikije. Iri sesengura risuzuma ikibazo kiri ku isoko ry'uturemangingo twa lithium two mu rwego rwa B mu Bushinwa, ibyago byo kongera gukoreshwa mu buryo butari bwo ndetse n'ibisubizo birambye.
Gusubiramo bateri za lithium EV zasigaye (uturemangingo twa bateri twa Grade B) ni ingenzi cyane mu kubungabunga umutungo kamere no kurengera ibidukikije. Iyo ubushobozi bwa bateri bugabanutse bukagera kuri 60%, inganda z'imodoka zikora ibikorwa byo gusenya no kuvugurura umwuga kugira ngo zikoreshe uturemangingo twasubijwe mu buryo bushya.uburyo bwo kubika ingufu z'izuba, imodoka zitwara imizigo, n'izindi porogaramu binyuze mu gukoresha imodoka zica mu mazi.
Ku bateri zitagomba gukoreshwa mu buryo bwa kabiri, uburyo bugezweho bwo gukurura ibyuma by'ingenzi nka lithium, nickel, na cobalt, bikazavamo ibikoresho bya bateri fatizo kugira ngo bigere ku ruziga rw'umutungo.
Ibipimo byo kugabanyirizwa ibiciro no gukoresha neza ibikoresho byo kongera gukoresha
Agaciro gasigaye k'amabati ya lithium ion yavuye mu kazi (coefficient yo kugabanyirizwa ibiciro) gatandukana bitewe n'imiterere.
- 1. Bateri ziterwa na electrolyte: Igipimo cyo kugabanyirizwa 30%-50% bitewe n'ibyago byo kwandura.
- 2. Bateri ziterwa na electrolyte zitarimo electrolyte: Kugera ku gipimo cyo kugabanyirizwa ibiciro kugeza kuri 60-80%, kuko ibikoresho bya cathode/anode bitanduye byemerera icyuma kuzamukaho 95% cyangwa hejuru.
Uburyo butemewe n'amategeko bwo kongera gukoresha ibikoresho bubangamira ibidukikije
Muri iki gihe, hafi 70% bya bateri za EV zakoreshejwe zijyanwa mu masoko adagenzurwa. Amaduka mato adafite uruhushya cyangwa ibyemezo by’ibidukikije akoresha ibiciro biri hasi kugira ngo arushe ikigo cy’abakoresha bateri za lithium. Ibi bikorwa binyuranyije n’imisoro, amabwiriza y’umutekano, n’ibikorwa birengera ibidukikije, bigashyira imbere inyungu y’igihe gito kuruta iy’uburambe.
Ingaruka ku bidukikije n'ubukungu ziterwa no kongera gukoresha ibikoresho mu buryo butari bwo
- ▲Kugarura ibikoresho mu buryo budahwitse: Uburyo bwo gutwika (urugero, gutwika, gusohora aside) butanga umusaruro uri munsi ya 50% by'igipimo cyo kugarura ibyuma ugereranije na >90% mu bigo byemewe bikoresha hydrometallurgy cyangwa vacuum pyrolysis
- ▲ Ingaruka z'umwanda:Electrolyte Kumeneka kw'amazi n'imyuka ihumanya (urugero: hydrogen fluoride, ibyuma biremereye) Byanduza ubutaka/amazi.
- ▲ Ihungabana ry'Isoko:Byavuguruwe cyangwa byatunganyijwe nabibateri za litiyumu-ion zikora ku buryo bwimbitsekongera kwinjira mu masoko, byongera ibyago by’umutekano no kubangamira intego z’ubukungu bushingiye ku ruziga.
Uru ruhererekane rudakurikije amategeko rusesagura umutungo kamere mu gihe rubangamira urusobe rw'ibinyabuzima n'ubuzima rusange. Gushyiraho imiyoboro yemewe yo kongera gukoresha ibikoresho biracyari ingenzi mu iterambere rirambye rya EV.
Kugira ngo hakemurwe akajagaribateri ya litiyumuuburyo bwo kongera gukoresha ibikoresho, dukeneye uburyo bwuzuye buhuza kugenzura amategeko, inyungu ku isoko, n'ibisubizo by'ikoranabuhanga:
- ⭐Amategeko: Kwihutisha amategeko kugira ngo habeho gukurikirana ibintu byose no gushyiraho ibiciro bihindagurika bifitanye isano n'iby'igihe kizaza by'ibyuma, bishyigikiwe n'igabanuka ry'imisoro.
- ⭐Amahame ngenderwaho mu nganda: Hazamurwa inzitizi zo kwinjira kugira ngo hakurweho abakinnyi badafite ibyangombwa kandi hakomezwe iyubahirizwa ry’amategeko mu turere twose tw’igihugu hifashishijwe ibikoresho byo kugenzura abaturage.
- ⭐Udushya: Gutera inkunga ikoranabuhanga ryo gusana ibintu mu buryo butangiza ibidukikije no kuringaniza ibyago biri ku isoko binyuze mu gutanga amakuru hakiri kare.
Ubu buryo bugamije kuzamura igipimo cyemewe cyo kongera ibikoresho byo kongera gukoresha ibikoresho kuva kuri 30% kugera hejuru ya 85%, bigatuma habaho inganda zirambye zigira akamaro haba mu kongera gukoresha ibikoresho byo kongera gukoresha ibikoresho no kurengera ibidukikije.
Umwanzuro
Ikiganiro ku birebana na bateri ya B kigaragaza gutandukana hagati y’inyungu z’igihe gito n’iterambere rirambye. Nubwo uturemangingo twa lithium-ion ya B twongerewemo dushobora kugaragara nk’aho duhendutse bitewe n’ibiciro byatwo byagabanijwe (agaciro gasigaye ka 30%-80%), ubushobozi bwacu bwo kugurwa akenshi buturuka ku nzira z’uburiganya: amahuriro atemewe n’amategeko anyuranyije n’amategeko agenga umutekano, akwepa imisoro, kandi agakoresha uburyo bwo kongera gukoresha ibikoresho byangiritse bugarura <50% by’ibyuma by’ingenzi. Ibi ntibipfa ubusa umutungo kamere gusa ahubwo binagira ingaruka zikomeye—umwanda w’uburozi, ibyago by’inkongi z’umuriro ziterwa na bateri zidakora neza, ndetse n’ibyangiritse mu buryo bw’urusobe rw’ibinyabuzima mu gihe kirekire.
Niyo mpamvu hari uburyo bwinshi bwo kubika bateri za lithium buhendutse ku isoko ubu. Ku bigo by'ubucuruzi, gushyira imbere ibiciro bihendutse bya Grade BUturemangingo twa bateri ya LiFePO4ni ubukungu bw'ikinyoma. Uturemangingo tudakora neza dukomoka ku miyoboro idakora neza yo kongera gukoresha ibintu mu buryo bunyuranyije n'amategeko, bigabanya icyizere cy'imikorere y'ikoranabuhanga kandi bigashyira abakoresha mu bibazo byemewe n'amategeko n'iby'ibanga. Mu buryo bunyuranye, uturemangingo twa bateri two mu cyiciro cya A—dukorerwa munsi y'igenzura rikomeye ry'ubuziranenge hamwe n'ibikoresho fatizo bishobora gukurikizwa—bituma ibyuma bisubizwa inyuma ku gipimo cya >95% mu buryo bwemewe bwo gufunga, bigatuma umutekano n'ubuzima bw'umuntu birushaho kuba byiza.
Inzira irasobanutse: Kongera umusaruro w’uturemangingo two mu rwego rwa A (ubu ni 87%) no gushyira mu bikorwa amabwiriza akaze yo kongera gukoresha ibikoresho bizatera imbere mu nganda. Guhitamo abatanga bateri za lithium bubahiriza amategeko si icyemezo cy’ubucuruzi gusa; bigaragaza kwiyemeza kubungabunga ibidukikije no kubungabunga umutekano mu mikorere. Iri hitamo ryemeza ko amasosiyete ahuza n’imikorere irambye mu gihe arinda ibikorwa byayo ingaruka zishobora kubaho. Mu kwanga ubundi buryo butari bwiza no gushora imari mu bisubizo byemewe byo mu rwego rwa A, abafatanyabikorwa babona inyungu irambye mu gihe barinda urusobe rw’ibinyabuzima n’ubuzima rusange.
