18650 lithiamu batire poyambirira amatanthauza NI-MH ndi Lithium-ion batire.Tsopano imayimira betri ya Lithium-ion popeza batire ya NI-MH yakhala ikugwiritsidwa ntchito pafupipafupi.

18650 imatengera dzina lake kuchokera ku kukula kwa selo: 18.6 mm m'mimba mwake ndi 65.2 mm m'litali ndi kulemera kwa 47g.

LiFePO4(LFP) ndi LiNiaCobMncO2(NCM) ndi mitundu yotchuka kwambiri.Tesla wachita mayeso ochulukirapo a batri kuti apeze batire yabwino kwambiri yagalimoto yake yamagetsi ndipo 18650 ndiye wopambana.18650 idakhala maziko a chitukuko chaukadaulo wa batri muTeslakupanga mzere kuyambira pamenepo.

Asanalowe m'magalimoto amagetsi amagetsi, 18650 yakhala ikugwiritsidwa ntchito pazinthu zamagetsi monga laputopu, makamera, zomwe zimapangitsa kuti ikhale mtundu woyambirira, wolimba kwambiri wa batri ya lithiamu.Pambuyo pazaka zachitukuko, opanga amagwiritsa ntchito luso laukadaulo lomwe amapeza kuchokera kuzinthu zamagetsi zamagetsi pamabatire amgalimoto.

Poyerekeza ndi mitundu ina ya batri yotsika, 18650 imagwirizana kwambiri ndi mapulogalamu osiyanasiyana omwe ali ndi magetsi osiyanasiyana, apano, komanso kukula kwake.

18650 idayesedwa kuti inali yopanda poizoni, yoyaka, yosaphulika, komanso yopanda kuipitsidwa, pansi pa chiphaso cha RoHS.

Kukhazikika kwa kutentha pansi pa kutentha kwakukulu kumapambananso machitidwe ena a Li-ion.Imawona 100% yotulutsa pa 65 ℃.

Kuphatikiza apo, cell ya batri imasindikizidwa mu silinda yachitsulo, yomwe imalola kuthekera kocheperako.Chifukwa cha mawonekedwe ake ang'onoang'ono, okhala ndi mphamvu zochepa, kulephera kwa batire imodzi kumapangitsa kuti batire igwire ntchito.

Kwa iwo akunja makampani opanga njinga zamagetsi ngatiSuper73, mulingo wapamwamba kwambiri wotetezedwa ndi wofunikira kuti batire lisagwedezeke mukamakwera m'malo ovuta.Teslayakhala yosamala pakusankha batire chifukwa kagawo kakang'ono pakati pa ma cell a batire omwe amapangidwa ndi mikhalidwe yosiyanasiyana yamisewu atha kubweretsa zoopsa monga kuphulika.

Batire imodzi ya 18650 ya lithiamu ili ndi mphamvu ya 1200mAh - 3600mAh pomwe ena ali ndi 800mAh.Izi zimathandiza kuti batire ipitirire 5000mAh ngati itaphatikizidwa.

Pakulemera komweko, mphamvu ya batri ya 18650 imatha kukhala nthawi 1.5-2 kuposa mu batri ya NI-MH.Mlingo wodzitulutsanso ndi wotsika.

Malinga ndi zomwe zaperekedwa kuchokera ku Tesla, mphamvu yeniyeniyo imatha kukwera mpaka 250Wh/kg kuti ikwaniritse zofunikira zamagalimoto amagetsi a Tesla.

Batire ya 18650 imakhala ndi nthawi yayitali kwambiri poyerekeza ndi mabatire wamba.Moyo wozungulira ukhoza kukhala 1000-2000 pokonzekera bwino.Pambuyo pazaka zachitukuko, mapangidwe apangidwe, teknoloji yopangira zinthu ndi zipangizo ndizoyenera, zomwe zimalola kuti mtengo wochepetsera ntchito ndi wokonza ukhale wotsika.

Pakuchita bwino kwake, batire ya lithiamu ya 18650 imapezekanso mkatiSuper73Mizere yopangira, mtundu wotchuka kwambiri wa njinga zamagetsi zakale ku US.

Komabe, batire ya lithiamu ya 18650 ikuyang'anizanabe ndi zovuta zina monga kudziwotcha kwambiri, magulu ovuta komanso kulipira pang'onopang'ono, zomwe ndi chifukwa chenichenicho chomwe Tesla akugwirizana ndi chimphona cha batri Panasonic kuti apange batri ya 21700 ya lithiamu.

Amanenedwa kuti ndi batri ya lithiamu yotsika mtengo kwambiri yomwe ili ndi mphamvu zapadera kwambiri pamizere yopanga misa.

Diameter 21mm, Utali 70mm, Kulemera 68g.

Chithunzi 1 - Kusiyana kwa kusunga mphamvu (Kumanzere) ndi moyo wozungulira (Kumanja) pakati pa 18650 ndi 21700

Kuthekera kwa selo limodzi kumawonjezeka ndi50%

Batire ya lithiamu ya 21700 yopangidwa ndi Tesla, imatha kufika 3-4.8Ah pa selo.

 

Zowonjezera 20% za mphamvu zenizeni zamakina a batri

Malinga ndi deta yochokera ku Tesla, batire ya 18650 ili ndi mphamvu zochulukirapo pafupifupi 250Wh/kg pomwe 21700 imatha kukwera mpaka 300Wh/kg.

 

Kupulumutsa 9% pamtengo wamagetsi a batri

Kuchokera pakuwunika kwa Tesla, mtengo wa batri uli pafupifupi $170/Wh ndi $185/Wh ya 21700 ndi 18650 motsatana.Model 3 yachepetsa bwino mtengo wake ndi 9% pamagetsi a batri.

 

10% kupepuka kulemera

Ngakhale batire ya 21700 ili ndi kukula kwakukulu, imakhala ndi mphamvu zapadera mu selo limodzi, zomwe zikutanthauza kuti chiwerengero cha maselo amodzi ofunikira kuti mphamvu zina ziwonongeke zimachepetsedwa ndi 33%.Ndikosavutanso kuwongolera batire la mapulogalamu osiyanasiyana.Komanso, ngati maselo ocheperako amafunikira, kusowa kwazitsulo ndi zida zamagetsi kumathandizira kuti batire ionde.

Akuti Super73 ikuyenera kusintha 18650 ndi 21700 kuti ipange zochuluka posachedwa, kuyambira ndi mtundu wogulitsa kwambiri.RX.

 

 

Pali zambiri zofanana pankhani ya mizere yopangira batri ndi njira zake.Chifukwa chake ndizotheka kusintha kupanga batire ya 18650 kukhala 21700's posintha zina mwazomwe zidapangidwa kale.
