Sezvo Tesla akazivisa kugadzirwa kwe21700mabhatiri emagetsi ndokuaisa kuModel 3 modhi, iwo21700simba rebhatiri dutu rapfuura.Pakarepo mushure meTesla, Samsung yakaburitsawo nyowani21700 bhatiri.Inotiwo kuwanda kwesimba rebhatiri idzva rakapetwa zvakapetwa kaviri bhatiri riri mukugadzirwa, uye bhatiri paki rinoumbwa nebhatiri idzva rinogona kuchajwa mubhatiri rekuwedzera nerwendo rwemakiromita mazana matatu nemakumi manomwe mukati memaminitsi makumi maviri.Kutarisana ne21700musika webhatiri remagetsi, ams yakagadzirira.Mapulagi akadai seXT60 akatevedzana anogona kupfuura 30A akakwenenzverwa pamusika kwemakore anopfuura gumi uye anoshandiswa zvakanyanya mumotokari dzemagetsi, marobhoti akangwara, midziyo yekuchengetedza simba, nezvimwe. Muindasitiri yekushandiswa kwebhatiri ye lithium, inovimbwa zvakanyanya ne vatengi.

Kufanana ne18650 bhatiri, iye Tesla21700 bhatiriiriwo imwe ye cylindrical lithium mabhatiri.Pakati pavo, "21" inoreva bhatiri rine dhayamita ye21mm, "70" inoreva kureba kwe70mm, uye "0" inomiririra cylindrical bhatiri.

Tesla anotora danho rekutanga

Tesla akatanga chirongwa21700 bhatirikwete kutungamira nzira yetekinoroji, asi chaizvo nekuda kwekumanikidzwa kwemutengo.Ams 'inokurumidza yekubatanidza zvigadzirwa zvinotora yakawanda-yevatengi yakabatana tsvagiridzo uye kusimudzira modhi kudzikisa mutengo kune vatengi uku uchisimbisa mhando.

Pakutanga kwechirongwa cheModel 3, Musk akaisa mutengo we35,000 US madhora emotokari iyi, asi kana yekutanga.18650 bhatiriichiri kushandiswa, pachava nemigumisiro miviri, zvichida kuve nechokwadi chokuti hupenyu hwebheteri hunodarika mutengo, kana kuti kuve nechokwadi chokuti mutengo unoderedzwa.Kutsungirira kwakaoma kubvuma kune "picky" Musk.Saka mubvunzo ndewekuti kune bhatiri rinogona kuderedza mutengo uchichengetedza hupenyu hwebhatiri.Mhinduro ndeyekuti21700 mabhatiri.

Kunyangwe iyo18650 bhatiriakaita zvipo zvikuru pakusimuka kwaTesla, Musk pachake akagara asina chokwadi nazvo.About the21700uye18650 mabhatiri, Musk akati pasocial media: Kubuda kwe18650 bhatirizvachose tsaona yezvakaitika kare.Chiyero chezvigadzirwa zvekutanga, ikozvino chete21700 mabhatiriinogona kusangana nekuita kwebhatiri zvinodiwa zvemotokari dzemagetsi.

Indasitiri vaongorori vanotenda kuti simba density ye21700-mhando mabhatiriyakakwirira kupfuura yevanozivikanwa18650-mhando mabhatiri, uye mutengo uchaderedzwa mushure mekuunganidza.Sarudzo ye21700haisi nekuti kuita kwayo kwakakwana kuri nani pane mamwe mamodheru, asi mhedzisiro yehuwandu hwehuwandu hwezvinhu zvemuviri uye hupfumi.

Zvinonzi simba density ichi21700 bhatirisystem inenge 300Wh/kg, iyo inopfuura 20% yakakwirira kupfuura iyo18650 bhatirisimba remagetsi rinoshandiswa mukutanga Model S. Kuwanda kwesero kunowedzerwa ne35%, asi mari yehurongwa inoderedzwa ne10%.Musk akati: Iyi seti ye21700 mabhatiriparizvino ndiro bhatiri rine simba repamusoro-soro uye mutengo wakaderera pakati pemabhatiri anogadzirwa-zhinji.

Zvakanakira zviri pachena, asi zvazvakaipira zvakakodzera kungwarira

　　21700 bhatiriine zvakanakira zvitatu.Kuwanda kwesimba kwesero rimwe chete neboka kwakagadziridzwa zvakanyanya.Kutora21700 bhatiriyakagadzirwa naTesla semuenzaniso, mushure mekuchinja kubva ku18650model kune21700modhi, bhatiri sero simba rinogona kusvika 3 ~ 4.8Ah, iri kuwedzera kukuru kwe35%.Mushure meboka, simba remagetsi richiri kuwedzera ne20%.

Nekuda kwehuwandu hwesimba hwemaseru, huwandu hwemaseru ebhatiri anodiwa pasi pesimba rimwechete anogona kudzikiswa neinenge 1/3.Ndichiri kuderedza kuoma kwehurongwa hwekutonga, zvakare inoderedza huwandu hwesimbi zvimiro uye magetsi ekushandisa anoshandiswa mubhatiri pack.Nekuda kwekuderedzwa kwehuwandu hwemamonomers anoshandiswa uye kudzikiswa kwekushandiswa kwezvimwe zvishongedzo, huremu hwesimba rebhatiri sisitimu inokwenenzverwa pasi pechisimbiso chekuvimbisa huwandu hwakafanana.Mushure mekunge Samsung SDI ichichinjira kune imwe seti ye21700 mabhatiri, zvakaonekwa kuti uremu hwehurongwa hwakaderedzwa ne10% kana ichienzaniswa nebheteri yemazuva ano.

Sezvo hukuru hwesero hunogona kuitwa hukuru uye kukwanisa kwesero kunogona kuwedzerwa, wadii kushandisa sero ine hukuru hukuru uye kukwanisa?

Kazhinji kutaura, kuwedzera kwehukuru hwemuviri wecylindrical cell hakungo wedzera simba remagetsi, asi zvakare kunoderedza hupenyu hwekutenderera uye chiyero chesero.Maererano nekufungidzira, kune yega yega 10% kuwedzera kwehuwandu, hupenyu hwekutenderera huchaderedzwa ne20%;mutero uye chiyero chekubuda chichaderedzwa ne30-40%;panguva imwecheteyo, kutonhora kwebhatiri kuchakwira ne20%.

Kana saizi ikaramba ichiwedzera, kuchengetedzeka uye kuchinjika kwesero rebhatiri kuchaderedzwa, izvo zvinozowedzera zvisingaonekwe njodzi dzinogona kuitika dzekuchengetedza uye kuomerwa kwekugadzira kwemotokari nyowani dzesimba.Ichi ndicho chikonzero mabhatiri makuru ecylindrical akadai se26500 uye 32650 asina kukwanisa kutora musika mukuru pamwero mukuru.chikonzero.

Theoretically, zvichienzaniswa ne18650 bhatiri, bhatiri re21700 rine hupenyu hupfupi, nguva yakareba yekuchaja ine simba rakafanana uye kuchengetedzwa kwakaderera.Kumotokari dzemagetsi, kuchengeteka nguva dzose ndiyo inonyanya kukosha.Kuti udzivise moto nekuda kwekukwira kwakanyanya kwekushisa kwemabhatiri mahombe, bhatiri yekutonhodza system inofanirwa kugadzirwa zvine musoro.Panguva imwecheteyo, zvakakosha zvikuru kusarudza inonzwisisika uye yepamusoro-soro21700 bhatiriplug.The21700lithium bhatiri interface yeAms inoshandisa V0 murazvo unodzoreredza zvinhu zvakaita sePA66, inoshingirira kune yakakwirira uye yakaderera tembiricha.Zvikamu zvesimbi zvinoshandisa dhizaini yemuchinjikwa uye yakanaka kupisa kupisa kuita.Ndiyo21700 lithium bhatiriconnector.Chisarudzo chakanakisisa.

Inogona21700tsiva18650?

Tichitarisa kubva kumitemo yenyika yesimba remagetsi emagetsi e-lithium mabhatiri, muna 2020, simba remagetsi emagetsi emagetsi emagetsi achapfuura 300Wh / kg, uye simba remagetsi emagetsi emagetsi emagetsi richasvika 260Wh / kg.Zvisinei, the18650 bhatirihaigone kuita ichi chinodiwa chehunyanzvi, uye kuwanda kwemabhatiri mazhinji epamba ari pakati pe100 ~ 150Wh/kg.

Pasi penguva-zvishoma mamiriro, chigadzirwa modhi yekuvandudza inokurumidza kupfuura kufambira mberi kwezvinhu, saka iyo21700 bhatiri, iyo inowedzera kuwanda kwesimba nekuwedzera vhoriyamu yayo, ichava isingadzivisiki kutarisisa kwakakosha kumabhizinesi.Yakabatanidzwa neTesla's hombe indasitiri pesvedzero, bhatiri iri rinogona kuzove rinotevera cylindrical bhatiri yekuvandudza maitiro.Nekudaro, zvakaoma kuona kana makambani epamba achaendesa21700 mabhatirisezvavakaita kare nemabhatiri e18650.Uye the18650 bhatiriine nhoroondo refu yebudiriro uye ine kuchinjika kwakasimba.Pamusoro pekushandiswa mumunda wemotokari dzemagetsi, inogonawo kuonekwa mune dzimwe nzvimbo dzakadai semakombiyuta emabhuku, 3C digital, drones, uye zvishandiso zvemagetsi.

For the21700 lithium bhatiri, hapana cheni inoshanda yeindasitiri, iyo pasina mubvunzo inowedzera mutengo uye inotadzisa kufambira mberi kwekusimudzira.Panyaya iyi, mhinduro yaTesla ndeyekutanga kugadzirwa kwakakura mufekitori yegigabit, yakabata kurongeka kwe500,000 Model 3, uye nekudiwa kukuru kweSun City, Tesla inokwana kugaya zvakabuda.Asi nzira iyi inongogumira kuTesla, iyo yakaoma kune vamwe vazhinji vanogadzira.

Zvakare, iyo yemba yemagetsi bhatiri musika yakangowedzera zvishoma nezvishoma mumakore achangopfuura.Mazhinji emitsetse yekugadzira akagadzirirwa kugadzirwa kwe18650 mabhatiri, uye kunyange mamwe makambani ekugadzira kugona mumakore mashoma anotevera achagadzirirwa18650.Zvinogona kuoneka kuti iyo indasitiri ndiyo The18650 bhatiriachiri netariro kwenguva yakareba.Uye mukusimudzirwa kwe21700 mabhatiri, mitemo yenyika ine chekuita nehukuru hwebhatiri ndiyo kiyi yekuona magumo e21700 mabhatiri.

Hazvina mhosva kuti chii, musika mutsva wemotokari yemagetsi uri kufambira mberi nekukurumidza, uye musika wevatengi wekupedzisira une chido chekukurumidzira chehupenyu hwebhatiri.Iyo inosarudza kuti vagadziri vanozopa pekutanga kune yakakwirira-density mabhatiri ane zvirinani kuita kwese, uye marongero anogadziridzwawo shanduko yemusika.

Nhasi, Tesla akatungamira kupinda mu21700 bhatirihondo.Vamwe vanogadzira mabhatiri epamba vanosarudza kutevera, uye vamwe vachiri kumirira.Izvi zvinogona kunge zviri zvekubheja kana mabiko.
