18650 batiri ya lithium mubyukuri yerekeza kuri bateri ya NI-MH na Litiyumu-ion.Ubu ahanini igereranya bateri ya Lithium-ion kuva bateri ya NI-MH yakoreshejwe mugihe gito.

18650 ibona izina ryayo kuva mubunini bwakagari: 18,6 mm z'umurambararo na mm 65.2 z'uburebure hamwe na 47g.

LiFePO4 (LFP) na LiNiaCobMncO2 (NCM) nubwoko bukunzwe cyane.Tesla yakoze umubare munini wibizamini bya batiri kugirango imenye bateri nziza kumodoka yayo yamashanyarazi kandi 18650 niyo yatsinze.18650 yabaye ishingiro ryiterambere rya tekinoroji ya batiri muriTesla'Umusaruro Umurongo Kuva.

Mbere yo kwinjizwa mu nganda z’amashanyarazi, 18650 imaze igihe kinini ikoreshwa muri elegitoroniki nka mudasobwa zigendanwa, kamera, bigatuma iba ubwoko bwa mbere bwa batiri ya lithium.Nyuma yimyaka yiterambere, abayikora bakoresha iterambere rya tekiniki ryunguka kubicuruzwa bya elegitoroniki byabaguzi kuri bateri yimodoka.

Ugereranije nubundi buryo buke bwa bateri, 18650 irahuza cyane na progaramu zitandukanye zifite voltage zitandukanye, izubu, nubunini busabwa.

18650 yapimwe ko idafite uburozi, ikongoka, ntisukure, kandi nta kwanduza, byemejwe na RoHS.

Ubushyuhe bwumuriro munsi yubushyuhe nabwo buruta ubundi buryo bwa Li-ion.Irabona igipimo cyo gusohora 100% kuri 65 ℃.

Ibindi byinshi, selile ya bateri ifunze muri silindiri yicyuma, itanga amahirwe yo kuba ntoya.Bitewe nuburyo buto bwarwo, burimo ingufu nkeya, kunanirwa kwingingo imwe ya bateri ishyiraho ingaruka nkeya kumikorere ya bateri muri rusange.

Kuri ayo masosiyete yo hanze yamashanyarazi nkaSuper73, urwego rwo hejuru rwumutekano ni ngombwa kuri bateri kugirango irwanye gutungurwa mugihe ugenda ahantu habi.Teslayagize amakenga muguhitamo bateri kuko igice kiri hagati ya selile zituruka kumiterere itandukanye yumuhanda gishobora kuvamo ingaruka zikomeye nko guturika.

Batare imwe ya 18650 ya lithium ifite ubushobozi bwa 1200mAh - 3600mAh mugihe izindi zifite 800mAh.Iyi mikorere ituma bateri yashyizweho irenga 5000mAh niba ishyizwe hamwe.

Ku buremere bumwe, ubushobozi bwa bateri 18650 irashobora kuba inshuro 1.5-2 yibyo muri bateri ya NI-MH.Igipimo cyo kwikuramo nacyo kiri hasi.

Dukurikije amakuru yatanzwe na Tesla, urwego rwingufu rwihariye rushobora kugera kuri 250Wh / kg kugirango rwuzuze ibisabwa n’imodoka z’amashanyarazi za Tesla.

Batare ya 18650 ifite ibyiringiro birebire ugereranije na bateri zisanzwe.Ubuzima bwizunguruka burashobora kuba 1000-2000 mukubungabunga neza.Nyuma yimyaka yiterambere, igishushanyo mbonera, tekinoroji yo gukora nibikoresho birashoboye, bituma igiciro gito cyibikorwa no kubungabunga.

Kubikorwa byayo bitangaje, bateri ya lithium 18650 nayo irashobora kuboneka muriSuper73's imirongo yumusaruro, icyamamare cyamashanyarazi bikunzwe cyane muri Amerika.

Nyamara, bateri ya 18650 ya lithium iracyafite imbogamizi nko kwishyushya cyane, kwishyira hamwe bigoye no kwishyurwa gahoro, akaba arinimpamvu nyayo yatumye Tesla ifatanya nigihangange cya Panasonic mugutezimbere batiri ya lithium 21700.

Bivugwa ko ari bateri ya lithium ihenze cyane ifite ingufu zidasanzwe kumurongo wibyinshi.

Diameter 21mm, Uburebure 70mm, Uburemere 68g.

Igishushanyo 1 - Itandukaniro ryo kugumana ubushobozi (Ibumoso) nubuzima bwinzira (Iburyo) hagati ya 18650 na 21700

Ubushobozi bwakagari kamwe bwiyongereyeho50%

Batiri ya lithium 21700 yakozwe na Tesla, irashobora kugera kuri 3-4.8Ah kuri selile.

 

Inyongera 20% yingufu zihariye za sisitemu ya bateri

Dukurikije amakuru yaturutse muri Tesla, bateri ya 18650 ifite ingufu zingana na 250Wh / kg mu gihe 21700 zishobora kuzamuka zigera kuri 300Wh / kg.

 

Kuzigama 9% kubiciro bya sisitemu ya batiri

Duhereye ku isesengura rya Tesla, igiciro cya batiri yashyizweho ni $ 170 / Wh na $ 185 / Wh kuri 21700 na 18650.Model 3 yagabanije neza igiciro cyayo 9% kuri sisitemu ya batiri.

 

10% byoroshye muburemere

Nubwo bateri 21700 ifite ubunini bunini muri rusange, ifite ingufu zidasanzwe muri selile imwe, bivuze ko umubare wingirabuzimafatizo zikenewe ku mbaraga runaka ugabanukaho 33%.Biroroshye kandi gucunga bateri yashizwe mubikorwa bitandukanye.Byongeye kandi, nkutugingo ngengabuzima dukenewe, kubura ibyuma na electronics bizafasha sisitemu ya bateri guta ibiro.

Bavuga ko Super73 ishobora gusimbuza 18650 na 21700 kugirango ikorwe mu gihe gito, guhera ku cyitegererezo cy’abagurisha cyizaRX.

 

 

Hano haribintu byinshi bihuriweho iyo bigeze kumurongo wo gukora bateri nibikorwa.Birashoboka rero guhindura imikorere ya bateri 18650 ikagera kuri 21700 muguhindura bimwe mubishusho muburyo bwahoze bukora.
