18650 lithium bhatiri pakutanga inoreva NI-MH uye Lithium-ion bhatiri.Ikozvino inonyanya kumiririra Lithium-ion bhatiri sezvo NI-MH bhatiri rave richishandiswa mune shoma frequency.

Iyo 18650 inowana zita rayo kubva muhukuru hwesero: 18.6 mm muhupamhi uye 65.2 mm kureba nehuremu hwakapoteredza 47g.

LiFePO4(LFP) neLiNiaCobMncO2(NCM) ndiwo marudzi ane mukurumbira.Tesla akaita nhamba yakakura yekuedza kwebhatiri kuitira kuti awane bhatiri rakanakisa remotokari yake yemagetsi uye 18650 ndiye anokunda.Iyo 18650 yakave hwaro hwekuvandudza tekinoroji yebhatiri mukatiTeslamutsara wekugadzira kubvira ipapo.

Isati yagamuchirwa muindasitiri yemotokari yemagetsi, iyo 18650 yagara ichishandiswa mumagetsi senge laptops, makamera, izvo zvinoita kuti ive yekutanga, yakanyanya kugadzikana mhando yelithium bhatiri.Mushure memakore ebudiriro, vagadziri vanoshandisa kuvandudzwa kwehunyanzvi kunowanikwa kubva kune zvigadzirwa zvemagetsi zvevatengi pamabhatiri emotokari.

Kana ichienzaniswa nemamwe mafomu akaderera ebhatiri, iyo 18650 inoenderana zvakanyanya neakasiyana maapplication ane akasiyana voltage, azvino, uye saizi zvinodiwa.

Iyo 18650 yakaedzwa kuti haina chepfu, inopisa, isingaputike, uye isina kusvibiswa, pasi pechitupa cheRoHS.

Thermal kugadzikana pasi pekupisa kwakanyanya kunodarika mamwe maLi-ion masisitimu.Iyo inoona 100% yekuburitsa chiyero pa65 ℃.

Uyezve, bhatiri sero rakavharwa musimbi cylinder, iyo inobvumira mukana wehukuru hudiki.Nekuda kwechimiro chayo chidiki, chine simba shoma, kutadza kwebhatiri rimwe chete yuniti inoburitsa kushomeka kwekuita kwebhatiri rose.

Kune avo vekunze emagetsi bike company likeSuper73, yakakwirira safty level yakakosha kuti bhatiri rirambe richivhundutsa kana uchifamba munzvimbo dzakashata.Teslayave yakangwarira pakusarudza bhatiri sezvo chikamu chiri pakati pemasero ebhatiri anogadzirwa nemamiriro akasiyana emigwagwa anogona kukonzera njodzi dzakakomba sekuputika.

Imwe 18650 lithium bhatiri ine capacitance ye1200mAh - 3600mAh nepo vamwe vaine kutenderera 800mAh.Ichi chinogonesa bhatiri seti kuti ipfuure 5000mAh kana ikaiswa pamwechete.

Pahuremu humwe chete, huwandu hwebhatiri re18650 hunogona kuita 1.5-2 nguva dzeiyo muNI-MH bhatiri.The self-discharge rate zvakare yakaderera.

Zvinoenderana nedata rakapihwa kubva kuTesla, iyo chaiyo yesimba nhanho inogona kuenda yakakwira kusvika 250Wh/kg kuti isangane nezvinodiwa zvakasiyana zveTesla mota dzemagetsi.

Bhatiri re18650 rine tarisiro yakarebesa kana ichienzaniswa nemabhatiri enguva dzose.Hupenyu hwekutenderera hunogona kuva 1000-2000 pasi pekugadzirisa kwakakodzera.Mushure memakore ebudiriro, dhizaini yekugadzira, tekinoroji yekugadzira uye michina inokwanisa, ichibvumira yakaderera mutengo wekushanda nekugadzirisa.

Nekuita kwayo kunoshamisa, iyo 18650 lithium bhatiri inogonawo kuwanikwa mukatiSuper73Mitsetse yekugadzira, inonyanya kufarirwa mabhasikoro emagetsi emagetsi muUS.

Nekudaro, iyo 18650 lithium bhatiri ichiri kutarisana nezvimwe zvipingamupinyi senge kuzvidziyisa, kuomesesa kuita mapoka uye kunonoka kuchaja, ndicho chikonzero chaicho icho Tesla achibatana nebhatiri hofori Panasonic kugadzira iyo 21700 lithium bhatiri.

Inonzi ndiyo inonyanya kudhura-inoshanda lithium bhatiri ine yakanyanya kujeka simba pamitsetse yekugadzira mizhinji.

Diameter 21mm, Kureba 70mm, Huremu 68g.

Mufananidzo 1 - Musiyano wekuchengetedza simba (Kuruboshwe) uye hupenyu hwekutenderera (Kurudyi) pakati pe18650 ne21700

Kugona kwesero rimwe chete kwakawedzera ne50%

Iyo 21700 lithium bhatiri yakagadzirwa naTesla, inogona kusvika 3-4.8Ah pasero.

 

Kuwedzera 20% yesimba chairo rebhatiri system

Zvinoenderana nedata kubva kuTesla, iyo 18650 bhatiri ine simba density inosvika 250Wh/kg apo 21700 inogona kukwira kusvika 300Wh/kg.

 

Kuchengetedza 9% pamutengo webhatiri system

Kubva pakuongorora kwaTesla, mutengo webhatiri seti ungangoita $170/Wh uye $185/Wh ye21700 uye 18650 zvakateerana.Model 3 yakabudirira kuderedza mutengo wayo ne9% pabhatiri system.

 

10% kureruka mukurema

Kunyangwe bhatiri re21700 riine saizi yakakura, inobata simba rakanyanya musero rimwe chete, zvinoreva kuti huwandu hwemasero anodiwa kune rimwe simba hunodzikiswa ne33%.Zvakare zvakareruka kubata bhatiri seti kune akasiyana maapplication.Uyezve, semasero mashoma anodiwa, kusavapo kwesimbi uye zvemagetsi zvikamu zvichabatsira bhatiri system kuderedza uremu.

Zvinonzi Super73 inogona kutsiva iyo 18650 ne21700 yekugadzirwa kwakawanda munguva pfupi iri kutevera, kutanga nemhando yepamusoro yekutengesa.RX.

 

 

Pane zvakawanda zvakafanana kana zvasvika kune mitsara yekugadzira bhatiri uye maitiro.Saka zvinokwanisika kushandura kugadzirwa kwe18650 bhatiri kusvika 21700's nekushandura mamwe magadzirirwo mune yaimbova kugadzirwa system.
