Kuva Tesla yatangaje umusaruro wa21700amashanyarazi ya batiri hanyuma uyashyire mubikorwa bya Model 3 ,.21700amashanyarazi ya batiri yamashanyarazi.Nyuma ya Tesla, Samsung nayo yasohoye agashyaBatare 21700.Ivuga kandi ko ubwinshi bwingufu za bateri nshya bwikubye kabiri ubw'umubyigano urimo gukorwa, kandi ipaki ya batiri igizwe na bateri nshya irashobora kwishyurwa mubushobozi bwa bateri ifite urugendo rw'ibirometero 370 muminota 20.Guhangana na21700ingufu za batiri isoko, ams iriteguye.Amacomeka nka XT60 yuruhererekane ashobora gutambuka 30A amaze imyaka irenga icumi asukuye kumasoko kandi akoreshwa cyane mumashanyarazi, robot zifite ubwenge, ibikoresho byo kubika ingufu, nibindi. abakiriya.

NkaBatare 18650, TeslaBatare 21700ni na imwe muri bateri ya litiro.Muri byo, “21 ″ bivuga bateri ifite diameter ya 21mm,“ 70 ″ bivuga uburebure bwa 70mm, naho “0 ″ igereranya batiri ya silindrike.

Tesla ifata iyambere

Tesla yatangijeBatare 21700ntabwo kuyobora icyerekezo cyikoranabuhanga, ariko mubyukuri biterwa nigitutu cyibiciro.Ibicuruzwa byihuta bya Ams bifata abakiriya benshi hamwe nubushakashatsi bwiterambere kugirango bagabanye ibiciro kubakiriya mugihe bafite ireme.

Mugutangira umushinga wa Model 3, Musk yashyizeho igiciro cyamadorari 35.000 USD kuriyi modoka, ariko niba ari umwimerereBatare 18650iracyakoreshwa, hazabaho ibisubizo bibiri, haba kugirango tumenye neza ko ubuzima bwa bateri burenze igiciro, cyangwa kwemeza ko igiciro cyagabanutse.Kwihangana biragoye kubyemera kuri "gutoranya".Ikibazo rero ni ukumenya niba hari bateri ishobora kugabanya ibiciro mugihe ubuzima bwa bateri.Igisubizo niBatteri 21700.

NubwoBatare 18650yagize uruhare runini mu kuzamuka kwa Tesla, Musk ubwe yamye ashidikanya kuri byo.Kubyerekeye21700naBatteri 18650, Musk yavuze ku mbuga nkoranyambaga: Kugaragara kwaBatare 18650ni impanuka yamateka.Igipimo cyibicuruzwa byambere, ubu gusaBatteri 21700irashobora kuzuza ibisabwa bya batiri yimodoka zamashanyarazi.

Abasesenguzi b'inganda bemeza ko ingufu zingana zaBateri zo mu bwoko bwa 21700ni hejuru kurenza iyizwiBateri yo mu bwoko bwa 18650, kandi ikiguzi kizagabanuka nyuma yo guterana.Guhitamo21700sibyo kuko imikorere yayo yuzuye iruta izindi ngero, ariko ibisubizo byuburinganire bwuzuye bwimiterere nubukungu.

Biravugwa ko ingufu zingana zibiBatare 21700sisitemu ni 300Wh / kg, irenga 20% kurenza iBatare 18650ubwinshi bwingufu zikoreshwa muburyo bwambere Model S. Ubushobozi bwakagari bwiyongereyeho 35%, mugihe ibiciro bya sisitemu bigabanukaho hafi 10%.Musk yagize ati: Iyi seti yaBatteri 21700kuri ubu ni bateri ifite ingufu nyinshi kandi nigiciro gito muri bateri zakozwe cyane.

Ibyiza biragaragara, ariko ibibi bikwiye kuba maso

　　Batare 21700ifite ibyiza bitatu.Ingufu zingirakamaro zingirabuzimafatizo imwe nitsinda ryaratejwe imbere cyane.GufataBatare 21700byakozwe na Tesla nkurugero, nyuma yo kuva kuri18650icyitegererezo kuri21700icyitegererezo, ubushobozi bwa selile ya batiri irashobora kugera kuri 3 ~ 4.8Ah, niyongera cyane rya 35%.Nyuma yitsinda, ubwinshi bwingufu buracyiyongera 20%.

Kubera ubwinshi bwingufu zingirabuzimafatizo, umubare wa selile ikenerwa munsi yingufu zimwe urashobora kugabanukaho hafi 1/3.Mugihe kugabanya ingorane zo gucunga sisitemu, bizanagabanya umubare wibyuma nibikoresho byamashanyarazi bikoreshwa mumapaki.Bitewe no kugabanuka kwumubare wa monomeri wakoreshejwe no kugabanya ikoreshwa ryibindi bikoresho, uburemere bwa sisitemu ya batiri yamashanyarazi buba bwiza cyane hashingiwe ku kwemeza ubushobozi bumwe.Nyuma ya Samsung SDI yahinduye kumurongo mushya waBatteri 21700, byagaragaye ko uburemere bwa sisitemu bwagabanutseho 10% ugereranije na batiri iriho.

Ko ubunini bwakagari bushobora gukorwa bunini kandi ubushobozi bwakagari bukaba bwiyongera, kuki utakoresha selile ifite ubunini nubushobozi?

Muri rusange, kwiyongera k'ubunini bw'umubiri wa selile ya silindrike ntabwo bizongera ingufu zingana gusa, ahubwo bizanagabanya ubuzima bwikurikiranya nigipimo cya selile.Ukurikije ibigereranyo, kuri buri 10% byiyongera mubushobozi, ubuzima bwinzira buzagabanukaho 20%;igipimo cyo kwishyurwa no gusohora kizagabanuka 30-40%;icyarimwe, ubushyuhe bwa bateri buzamuka hafi 20%.

Niba ingano ikomeje kwiyongera, umutekano hamwe n’imihindagurikire y’akagari ka batiri bizagabanuka, ibyo bikaba byongera mu buryo butagaragara ingaruka zishobora guhungabanya umutekano ndetse n’ibibazo by’imodoka nshya zifite ingufu.Niyo mpamvu bateri nini ya silindrike nka 26500 na 32650 itashoboye kwigarurira isoko rusange murwego runini.impamvu.

Mubyukuri, ugereranije naBatare 18650, bateri ya 21700 ifite ubuzima bucye, igihe kinini cyo kwishyuza gifite ubushobozi bumwe n'umutekano muke.Ku binyabiziga byamashanyarazi, umutekano nigihe cyose cyambere.Kugirango wirinde inkongi y'umuriro bitewe n'ubushyuhe bukabije bwa bateri nini, sisitemu yo gukonjesha bateri igomba kuba yarateguwe neza.Igihe kimwe, ni ngombwa cyane guhitamo gushyira mu gaciro kandi bifite iremeBatare 21700Gucomeka.Uwiteka21700Imashini ya batiri ya lithium ya Ams ikoresha ibikoresho bya V0 flame retardant nka PA66, irwanya ubushyuhe bwo hejuru kandi buke.Ibice by'icyuma bifashisha umusaraba wubusa hamwe nubushyuhe bwiza bwo gukwirakwiza.NiBatiri ya litiro 21700umuhuza.Guhitamo neza.

Birashoboka21700gusimbuza18650?

Ukurikije umurongo ngenderwaho wigihugu kubijyanye nubucucike bwingufu za batiri ya lithium, mumwaka wa 2020, ubwinshi bwingufu za selile yumuriro uzarenga 300Wh / kg, naho ingufu za sisitemu ya batiri ikagera kuri 260Wh / kg.ArikoBatare 18650ntishobora kuzuza ibisabwa bya tekiniki, kandi ubucucike bwa bateri nyinshi zo murugo buri hagati ya 100 ~ 150Wh / kg.

Mugihe cyigihe gito, ibicuruzwa bitezimbere birihuta cyane kuruta iterambere ryibintu, bityoBatare 21700, byongera ingufu zingufu zongera ubwinshi bwabyo, byanze bikunze bizahinduka ibitekerezo byingenzi kubigo.Ufatanije ninganda nini za Tesla, iyi bateri irashobora guhinduka icyerekezo gikurikira cyiterambere rya batiri.Ariko, biragoye kumenya niba ibigo byimbere mu gihugu bizoherezaBatteri 21700nkuko babigize mbere hamwe na bateri 18650.KandiBatare 18650ifite amateka maremare yiterambere kandi ifite imiterere ihindagurika.Usibye gukoreshwa mubijyanye n’ibinyabiziga byamashanyarazi, birashobora no kugaragara mubindi bice nka mudasobwa yamakaye, 3C digitale, drone, nibikoresho byamashanyarazi.

KuriBatiri ya litiro 21700, ntamurongo ufatika winganda, uzashidikanya ko uzamura ibiciro kandi bikabuza iterambere ryiterambere.Ni muri urwo rwego, igisubizo cya Tesla ni ugutangiza umusaruro munini mu ruganda rwa gigabit, ufite itegeko rya 500.000 Model 3, kandi hamwe n’izuba rikenewe cyane Sun City, Tesla irahagije kugirango igabanye umusaruro.Ariko ubu buryo bugarukira kuri Tesla, bigoye kubandi bakora cyane.

Byongeye kandi, isoko ya batiri yingufu zo murugo yagutse buhoro buhoro mumyaka yashize.Imirongo myinshi yumusaruro yashyizweho kugirango ikorweBatteri 18650, ndetse nubushobozi bwibigo bimwe mumyaka mike iri imbere bizategurwa18650.Birashobora kugaragara ko inganda ari TheBatare 18650iracyafite ibyiringiro kumwanya muremure.No mukuzamuraBatteri 21700, politiki yigihugu ijyanye nubunini bwa batiri nurufunguzo rwo kumenya ibizabaBatteri 21700.

Ntakibazo, isoko yimodoka nshya yingufu iratera imbere byihuse, kandi isoko ryabaguzi rya nyuma rikeneye byihutirwa ubuzima bwa bateri.Igena ko abayikora bazashyira imbere bateri zifite ubucucike bukabije hamwe nibikorwa byiza muri rusange, kandi politiki nayo ihindurwa kugirango isoko rihinduke.

Uyu munsi, Tesla yafashe iyambere kugirango yinjire muriBatare 21700kurugamba.Bamwe mubakora bateri yo murugo bahitamo gukurikira, nabandi baracyategereje.Ibi birashobora kuba urusimbi cyangwa ibirori.
