I-18650 ibhetri ye-lithium ekuqaleni ibhekisela kwi-NI-MH kunye nebhetri ye-Lithium-ion.Ngoku ubukhulu becala imele ibhetri ye-Lithium-ion kuba ibhetri ye-NI-MH isetyenzisiwe kwi-frequency encinci.

I-18650 ifumana igama layo kwisayizi yeseli: 18.6 mm ububanzi kunye ne-65.2 mm ubude kunye nobunzima obujikeleze i-47g.

I-LiFePO4(LFP) kunye ne-LiNiaCobMncO2(NCM) zezona ntlobo zidumileyo.UTesla wenze inani elikhulu lovavanyo lwebhetri ukuze afumane eyona bhetri ibalaseleyo yemoto yakhe yombane kwaye i-18650 iphumelele.I-18650 yaba sisiseko sophuhliso lwetekhnoloji yebhetri kwiTeslaumgca wemveliso ukusukela oko.

Ngaphambi kokuba yamkelwe kumzi-mveliso wezithuthi zombane, i-18650 kudala isetyenziswa kwi-electronics efana neelaptops, iikhamera, nto leyo eyenza ukuba ibe yeyona ndlela yokuqala, eyona nto izinzileyo yebhetri ye-lithium.Emva kweminyaka yophuhliso, abavelisi basebenzisa uphuculo lobugcisa oluzuzwa kwiimveliso ze-elektroniki zabathengi kwiibhetri zemoto.

Xa kuthelekiswa nezinye iifom zebhetri ezikumgangatho ophantsi, i-18650 ihambelana kakhulu nezicelo ezahlukeneyo ezinombane ohlukeneyo, iimfuno zangoku kunye nobukhulu.

I-18650 yavavanywa ukuba ayinayo ityhefu, inokutsha, ayiqhumisi, kwaye ayinangcoliso, phantsi koqinisekiso lwe-RoHS.

Ukuzinza kwe-Thermal phantsi kobushushu obuphezulu kuphinda kudlule ezinye iinkqubo ze-Li-ion.Ibona i-100% yezinga lokukhupha kwi-65 ℃.

Ngaphezu koko, iseli yebhetri itywinwe kwi-cylinder yentsimbi, evumela ukuba kwenzeke ubungakanani obuncinci.Enkosi kwimilo yayo encinci, equlethe isixa esincinci samandla, ukusilela kweyunithi yebhetri enye kwizithuba zempembelelo encinci ekusebenzeni kwebhetri iyonke.

Kwezo nkampani zangaphandle zeebhayisekile zombane ezifanaSuper73, inqanaba eliphezulu lokhuseleko libalulekile kwibhetri ukuxhathisa ukothusa xa ukhwele kumhlaba orhabaxa.TeslaIlumkile ekukhetheni ibhetri njengoko iqhezu eliphakathi kweeseli zebhetri elenziwe ziimeko zendlela ezahlukeneyo linokubangela iingozi ezimandundu ezifana nokuqhambuka.

Ibhetri ye-lithium enye ye-18650 inamandla e-1200mAh - 3600mAh ngelixa abanye bejikeleze i-800mAh.Eli nqaku livumela ibhetri ukuba ihambe ngaphaya kwe-5000mAh ukuba zidibene.

Ngobunzima obufanayo, umthamo webhetri ye-18650 unokuba ngamaxesha angama-1.5-2 aloo bhetri ye-NI-MH.Izinga lokuzikhupha ngokwakho liphantsi.

Ngokutsho kwedatha enikezelwe nguTesla, inqanaba elithile lamandla linokuhamba ukuya kwi-250Wh / kg ukuhlangabezana nemfuno yoluhlu lweemoto zombane zeTesla.

Ibhetri ye-18650 inokulindela ixesha elide xa kuthelekiswa neebhetri eziqhelekileyo.Ubomi bomjikelezo bunokuba yi-1000-2000 phantsi kokugcinwa okufanelekileyo.Emva kweminyaka yophuhliso, uyilo lwesakhiwo, iteknoloji yokuvelisa kunye nezixhobo zifanelekile, zivumela iindleko eziphantsi zokusebenza kunye nokugcinwa.

Ngokusebenza kwayo okugqwesileyo, ibhetri ye-lithium ye-18650 inokufumanekaSuper73Imigca yemveliso, eyona idumileyo yakudala yeebhayisekile zombane uphawu e-US.

Nangona kunjalo, ibhetri ye-lithium ye-18650 isajongene nemiqobo efana nokuzifudumeza okuphezulu, ukudibanisa amaqela kunye nokutshaja okucothayo, esona sizathu sokuba uTesla asebenzisane nebhetri enkulu yePanasonic ukuphuhlisa ibhetri ye-lithium ye-21700.

Kuthiwa iyona bhetri ye-lithium enexabiso eliphezulu kakhulu elinamandla athile kwimigca yokuvelisa ubuninzi.

Ububanzi 21mm, Ubude 70mm, Ubunzima 68g.

Umzobo 1 - Umahluko wokugcinwa kwamandla (ngasekhohlo) kunye nobomi bomjikelezo (Ekunene) phakathi kwe-18650 kunye ne-21700

Umthamo weseli enye unyuke ngo50%

Ibhetri ye-lithium ye-21700 eyenziwe nguTesla, inokufikelela kwi-3-4.8Ah ngeseli nganye.

 

I-20% eyongezelelweyo yamandla athile enkqubo yebhetri

Ngokwedatha evela kuTesla, ibhetri ye-18650 inoxinano lwamandla malunga ne-250Wh/kg ngelixa i-21700 inokunyuka iye kuthi ga kwi-300Wh/kg.

 

Ukugcina i-9% kwiindleko zenkqubo yebhetri

Ukususela kuhlalutyo lukaTesla, ixabiso leebhetri zexabiso malunga ne-$ 170 / Wh kunye ne-$ 185 / Wh ye-21700 kunye ne-18650 ngokulandelanayo.Imodeli ye-3 iphumelele ukunciphisa iindleko zayo nge-9% kwinkqubo yebhetri.

 

I-10% ilula ngobunzima

Nangona ibhetri ye-21700 inobungakanani obukhulu ngokubanzi, ibamba amandla athile aphezulu kwiseli enye, oku kuthetha ukuba inani leeseli ezifunekayo kumandla athile liyancipha ngama-33%.Kwakhona kulula ukulawula iseti yebhetri kwizicelo ezahlukeneyo.Ngaphezu koko, njengoko iiseli ezincinci zifunekayo, ukungabikho kwentsimbi kunye nezixhobo zombane kuya kunceda inkqubo yebhetri ilahlekelwe ubunzima.

Kuthiwa i-Super73 inokuthi ithathe indawo ye-18650 kunye ne-21700 yemveliso yobuninzi kwixesha elifutshane, ukuqala ngemodeli engcono kakhulu yokuthengisa.RX.

 

 

Kuninzi okufanayo xa kuziwa kwimigca yokuvelisa ibhetri kunye neenkqubo.Ngoko ke kunokwenzeka ukuguqula ukuveliswa kwebhetri ye-18650 ukuya kwi-21700 ngokuguqula ezinye zeendlela zokucwangciswa kwindlela yokuvelisa yangaphambili.
