Igiciro kinini cy'ibikoresho fatizo by'ibikoresho bya ternary kizagira ingaruka mbi ku kwamamaza bateri za ternary lithium. Cobalt ni icyuma gihenze cyane mu bateri zitanga ingufu. Nyuma yo gucibwa inshuro nyinshi, ikigereranyo cya cobalt kuri toni imwe ni hafi 280000 yuan. Ibikoresho fatizo bya bateri ya phosphate ya lithium iron bikungahaye kuri fosifore na feri, bityo ikiguzi cyoroshye kugenzura. Kubwibyo, nubwo bateri ya ternary lithium ishobora kunoza cyane ubwoko bw'imodoka nshya zitanga ingufu, kubera umutekano n'ikiguzi, abakora ntibashyize hasi ubushakashatsi bwa tekiniki n'iterambere rya bateri ya phosphate ya lithium iron.

Umwaka ushize, Ningde era yasohoye ikoranabuhanga rya CTP (kuva kuri cell ujya kuri paki). Dukurikije amakuru yashyizwe ahagaragara na Ningde times, CTP ishobora kongera igipimo cy'ikoreshwa ry'ipaki ya bateri ku kigero cya 15%-20%, kugabanya umubare w'ibice bya bateri ku kigero cya 40%, kongera umusaruro ku kigero cya 50%, no kongera ubucucike bw'ingufu za bateri ku kigero cya 10%-15%. Kuri CTP, ibigo byo mu gihugu nka BAIC new energy (EU5), Weilai automobile (ES6), Weima automobile na Nezha automobile byagaragaje ko bizakoresha ikoranabuhanga rya Ningde era. VDL, uruganda rukora bisi rw'i Burayi, narwo rwavuze ko ruzayishyira ahagaragara mu mwaka utaha.

Kubera ko inkunga y’imodoka nshya zikoresha ingufu igenda igabanuka, ugereranyije na bateri ya lithium ya yuan 3 ifite agaciro ka 0.8 yuan /wh, igiciro cy’ubu cya 0.65 yuan /wh kuri sisitemu ya lithium iron phosphate ni cyiza cyane, cyane cyane nyuma yo kuvugurura tekiniki, bateri ya lithium iron phosphate ubu ishobora kongera ibirometero by’imodoka ikagera kuri kilometero 400, bityo yatangiye gukurura amaso y’ibigo byinshi by’imodoka. Amakuru agaragaza ko mu mpera z’igihe cy’impinduka muri Nyakanga 2019, ubushobozi bwa lithium iron phosphate bungana na 48.8% kuva kuri 21.2% muri Kanama kugera kuri 48.8% mu Ukuboza.

Tesla, umuyobozi w’inganda umaze imyaka myinshi akoresha bateri za lithium-ion, ubu agomba kugabanya ikiguzi cyayo. Dukurikije gahunda nshya y’inkunga y’imodoka zikoresha ingufu zo mu 2020, terefone za tram zidakoresha amafaranga menshi zirenga 300000 ntizishobora kubona inkunga. Ibi byatumye Tesla itekereza kwihutisha inzira yo guhindura ikoranabuhanga rya bateri ya lithium iron phosphate. Vuba aha, umuyobozi mukuru wa Tesla musk yavuze ko mu nama ye itaha ya "umunsi w’amabati", azibanda ku ngingo ebyiri, imwe ni ikoranabuhanga rya bateri rikora neza, indi ni bateri idafite cobalt. Inkuru ikimara gusohoka, ibiciro bya cobalt ku rwego mpuzamahanga byaragabanutse.

Bivugwa kandi ko igihe cya Tesla na Ningde barimo kuganira ku mikoranire ya bateri nke za cobalt cyangwa izitari cobalt, kandi fosifate y'icyuma ya lithium ishobora guhaza ibyifuzo by'icyitegererezo cya 3. Nk'uko Minisiteri y'inganda n'ikoranabuhanga rishinzwe itumanaho ibivuga, uburebure bw'icyitegererezo cya 3 ni kilometero 450, ubucucike bw'ingufu za sisitemu ya bateri ni hagati ya 140-150wh / kg, kandi ubushobozi bw'amashanyarazi bwose ni hafi 52kwh. Kuri ubu, ingufu zitangwa n'igihe cya Ningde zishobora kugera kuri 80% mu minota 15, kandi ubucucike bw'ingufu za bateri zifite imiterere yoroheje bushobora kugera kuri 155wh / kg, ibi bikaba bihagije kugira ngo bihuze n'ibisabwa byavuzwe haruguru. Bamwe mu basesenguzi bavuga ko niba Tesla ikoresha bateri ya lithium, ikiguzi cya bateri imwe cyitezwe kugabanukaho 7000-9000 yuan. Ariko, Tesla yasubije ko bateri zidafite cobalt zidasobanura bateri za lithium fer phosphate.

Uretse inyungu ku giciro, ubucucike bw'ingufu za bateri ya phosphate y'icyuma ya lithium imaze kugera ku gisenge cya tekiniki bwiyongereye. Mu mpera za Werurwe uyu mwaka, BYD yasohoye bateri yayo y'icyuma, ivuga ko ubucucike bw'ingufu zayo bwari hejuru ya 50% ugereranyije na bateri isanzwe y'icyuma ku gipimo kimwe. Byongeye kandi, ugereranyije na bateri isanzwe ya phosphate y'icyuma ya lithium, ikiguzi cya bateri y'icyuma cyagabanutseho 20% - 30%.

Bateri yitwa blade mu by’ukuri ni ikoranabuhanga ryo kunoza imikorere y’ikoreshwa ry’ipaki ya bateri binyuze mu kongera uburebure bw’ingirabuzimafatizo no kugorora ingirabuzimafatizo. Kubera ko ingirabuzimafatizo imwe ari ndende kandi irambuye, yitwa "blade". Birumvikana ko ubwoko bushya bw’imodoka zikoresha amashanyarazi za BYD buzakoresha ikoranabuhanga rya "blade bateri" muri uyu mwaka no mu utaha.

Mu minsi ishize, Minisiteri y’imari, Minisiteri y’inganda n’ikoranabuhanga mu itumanaho, Minisiteri y’ubumenyi n’ikoranabuhanga, na Komisiyo y’igihugu ishinzwe iterambere n’ivugurura bashyize ahagaragara itangazo rijyanye no guhindura no kunoza politiki y’inkunga ku modoka nshya zikoresha ingufu, ryagaragaje neza ko inzira yo gutwara abantu n’ibintu n’amashanyarazi mu nzego runaka igomba kwihutishwa, kandi inyungu z’umutekano n’ikiguzi bya fosifate ya lithium iron zitezweho gukomeza gutezwa imbere. Bishobora kuvugwa ko hamwe no kwihutisha buhoro buhoro umuvuduko wo gushyira amashanyarazi no kunoza ikoranabuhanga rijyanye n’umutekano w’amabati n’ubwinshi bw’ingufu, amahirwe yo kubaho kwa bateri ya fosifate ya lithium iron na bateri ya lithium iron ternary azaba menshi mu gihe kizaza, aho kuba uwazabisimbuza.

Ni ngombwa kandi kumenya ko icyifuzo cya 5g muri sitasiyo ya base kizatuma icyifuzo cya bateri ya phosphate ya lithium iron kizamuka cyane kikagera kuri 10gwh, kandi ubushobozi bwa bateri ya phosphate ya lithium iron bushyirwa muri 2019 ni 20.8gwh. Biteganijwe ko isoko rya phosphate ya lithium iron riziyongera vuba muri 2020, bikungukira mu kugabanya ikiguzi no kunoza imiterere y’irushanwa rya bateri ya feri ya lithium.
