Umzi-mveliso webhetri yeLithium wenze inkqubela phambili ebonakalayo yokufezekisa iimfuno zombane nezixhobo, kubandakanya izixhobo zamandla, iimoto kunye nezixhobo zonyango. Kule minyaka ingamashumi amabini idlulileyo, ubungakanani obahlukeneyo kunye neemilo ze-lithium buta Ivelisiwe ekuphenduleni ekuphenduleni kwemfuno. Iimodeli zefowuni ze-cylindrical zibone ukukhula okukhulu, nge-18650 kunye ne-21700 yeemodeli ezikhuphisana nobungakanani kunye nomthamo.
I-186555 i-COLCICS ZesiXhosa
Iseli yebhetri ye-18650, ibiwe yiPanasonic ngo-1994 kwaye yaqinisekiswa ngo-2013, imilinganiselo ye-18mm ububanzi kunye ne-6,5mm ubude. Inamandla asusela kwi-1,200 mah ukuya kwi-3,600 mah kwaye isebenza malunga ne-3.6 ukuya kwi-3.7 volts.
Imfuneko ifakwe ngo-2011 ngenxa yokunyuka kwezithuthi zombane ezinjengeTssa, ii-drones, kunye nezixhobo zonyango, ezikhokelela kwiiseli ezizigidi ze-2,55 zeebhiliyoni ze-2,55 zeebhiliyoni zivelise loo nyaka.
Nangona kunjalo, ibango liye lehla njengoko i-elektronics ihamba ngendlela yokuyila efune amandla aphezulu. Inkxalabo yokunqongophala kwebhetri ezinokubakho kwezithuthi zombane ezikhokelwa abavelisi beeseli eziphezulu.
Ukuhlangabezana nesidingo esikhulayo seebhetri eziphezulu zezakhono, iimodeli ezintsha ezinje nge-21700 zinokuba yimfuneko.
21700 iziseko zebhetri zebhetri ezingama-21700
Iiseli ezingama-21700, zaziswa ngo-2017 ngePanasonic naseTessa, zilinganisa i-21mm ubukhulu kunye ne-70mm ubude.
Zinkulu kwiiseli ezili-18650 kwaye zinike amandla ezi-4,000 ukuya kwi-5,000 mah ngesantya esithile se-3.6 ukuya kwi-3.7 volts.
Ifumaneka njengoko ikhuselwe (enezinto ezikhuselekileyo) okanye engakhuselekanga (ngaphandle kokhuseleko), ezi zibhengezo ze-cylindrical zinokuyihlambulula okanye ziyilo oluthile ukutshintsha i-18650 kwizithuthi zombane.
I-18650 vs i-21700 yeseli
Umthamo weseli
Umthamo webhetri owe-18650 iiseli unqunyelwe malunga ne-3,600mah ngenxa yesayizi yabo.
Ngokwahlukileyo, ibhetri engama-21700 inokuthi ifike kwinqanaba lama-5,000mma, elimele ukunyuka kwe-420.
Iindleko
Ulwazi lwaseburhulumenteni likaThela lubonisa ukuba inkqubo yebhetri ye-TSLA ixabisa i-15500 yebhetri ixabisa i-155 / kWh, ngelixa inkqubo ye-18650 ixabisa i-171 / kWh ixabisa i-171 / kWh ixabisa i-171 / kWh, kukhokelela ekunciphiseni kweendleko malunga ne-9%.
Iindleko eziphezulu ze-18650 zibangelwa yimfuno yayo yezixhobo ezingaphezulu zokufezekisa umthamo ofanayo. Umzekelo, ibhetri eyi-100 ye-100 ifuna iiyunithi ezingama-20 ze-5,000 yeeseli ezingama-21000 kodwa zidinga iiyunithi ezingama-3,300mah 18650 iiseli.
Ukuxinana kwamandla
Ibhetri engama-21700 ine ukuxinana kwamandla Phantse i-300 wh / kg, ngelixa i-18650 ifikelela kwi-250 kuphela i-wh / kg. Oku kuthetha ukuba ukuxinana kwamandla angama-21700 phantse ngama-20% aphezulu kunelo ye-18650.
Isicelo
- I-21700: Izithuthi zombane, izixhobo zamandla, ukusebenza kwe-elektroniki, i-drones
- I-18650: I-Flashlights, izixhobo zeVapoing, i-charger ephathekayo
Ulindelo lwexesha elizayo kumzi mveliso webhetri
Amacandelo e-elektroniki kunye namacandelo emoto atshintsha ukuya kwi-21700 yeseli ye-lithium ye-lithium yemveliso esebenza kakuhle kunye nomthamo ophuculweyo.
Ngelixa iiseli ze-pouch zinokuba neendleko eziphezulu zemveliso, zombini ezili-18650 kunye neeseli ezingama-21700 zibonelela ngeendlela zokuncitshiswa kweendleko. Ukuhambela phambili kwezobuchwephesha kulindeleke ukuba kube sezantsi kweendleko zokwenza iimoto ngokuhamba kwexesha.
Izikhundla ezingama-21700 ze-ratimes ezilinganayo njengendawo efanelekileyo yokutshintshwa ngo-18650; Nangona kunjalo, abavelisi basaza kusebenzisa iiseli ezili-18650 apho kufuna ubungakanani abancinci okanye amandla asezantsi kufuneka.
Njengoko ishishini livele, iibhetri ezilula ezikhanyayo ezinoyilo oluhlekisayo ziya kuhlala zifunekile, zikhupha utshintsho kwiiseli eziphezulu zexabiso ngelixa zivumela iinguqu ezigudileyo ukusuka kwi-18650 ukuya kwi-21700 ngaphandle komvusi opheleleyo.
Ukuqukumbela
Abavelisi beseli be-tier ephezulu batshintsha ukusuka kwi-18650 ukuya kwimodeli yeseli engama-21700. Njengoko olu luyilo luxhaphake ngakumbi, umahluko uya kuvela ngokusekelwe kwiimfuno zesicelo. Ukuqwalaselwa okuphambili kukubanakho kweeseli eziflethi; Ukuba iseli yeseli ihambelana nokusebenza kwe-cylindrical 21700, ibango liya kuphumela.
Nangona kunjalo, imfuno yeeseli ezili-18650 ziya kuqhubeka emkhosini, kwezonyango, kunye nezithuthi zemoto. Njengoko imakethi inamazwe anoyilo olunama-21700, abavelisi banokunciphisa ukuveliswa kweebhetri ezili-18650. Ukubonisana ne Umvelisi wepakethe yebhetri Njengebhetri yeHolo inokunceda iinkampani zokuvavanya iimfuno zangoku zebhetri kwaye zilindele utshintsho elizayo njengeetekhnoloji.
