Ngokweengxelo zemithombo yeendaba zangaphandle, uTesla usandula ukufaka isicelo selungelo lomenzi elitsha lokwahlula iiseli zebhetri ezineziphene ukuze zithintele ukuba zichaphazele kakubi iiseli zebhetri ezisebenzayo, ngaloo ndlela ziphucula ukhuseleko lwebhetri.

Imvelaphi yokuphuhliswa kweTesla yale patent kukuba ngenxa yokuba iiseli zebhetri ziya kuvelisa ubushushu ngexesha lenkqubo yokutshaja kwaye xa zikhupha amandla, uTesla wafumanisa ukuba iiseli zebhetri eziphosakeleyo ziya kuvelisa ukushisa, okuya kuchaphazela imisebenzi yeeseli zebhetri ezijikelezayo. Ibangela ukusilela okuqhubekayo kwebhetri. Ngoko ke, iye yavelisa ilungelo elilodwa lomenzi wechiza.

I-patent yeTesla ichaza inkqubo eyinkimbinkimbi eyenza i-interconnect layer (i-inter-connectivity layer) ebeka iliso kwaye ilungise ubushushu kunye noxinzelelo kwi-pack yebhetri ngokuhlukanisa amacandelo angalunganga.

I-Tesla Model 3 ixhotyiswe ngesizukulwana samva nje seebhetri, iiseli zebhetri ezingama-21700. UTesla ubonakalise ukuba iseli yebhetri inobuninzi bamandla obuphezulu kunayo nayiphi na iseli yebhetri yemoto yombane kuba inciphisa kakhulu umxholo we-cobalt, inyusa ngamandla umxholo we-nickel, kunye nenkqubo yebhetri igcina uzinzo olupheleleyo lwe-thermal. U-Tesla uphinde wachaza ukuba ukubunjwa kweekhemikhali ze-nickel-cobalt-aluminium i-electrode efanelekileyo ye-cell cell ye-Tesla yebhetri iphantsi kumxholo webhetri yesizukulwana esilandelayo.

Amalungelo awodwa omenzi kaTesla aphinde abonise ukuba ngaphandle kobunkokeli benkampani kwitekhnoloji yebhetri, isaqhuba izinto ezintsha.

Yintoni umlingo we21700?

Owona mahluko ucacileyo phakathi kwe-21700 kunye ne-18650 iibhetri ubukhulu obukhulu.

Ngenxa yokuthintelwa kokusebenza kwezixhobo zebhetri, ukonyuka koxinzelelo lwamandla ngokongeza umthamo omtsha kube yeyona nto iphambili kuqwalaselo lwenkampani. ilizwe lam liphakamisa ngokucacileyo ukuba ngo-2020, ubuninzi bamandla amandla e-lithium-ion iiseli zebhetri ziya kudlula i-300Wh / kg, kwaye ubuninzi bamandla beenkqubo zebhetri ze-lithium-ion ziya kufikelela kwi-260Wh / kg; kwi-2025, ubuninzi bamandla beenkqubo zebhetri ze-lithium-ion ziya kufikelela kwi-350Wh / kg. Iimfuno eziqhubekayo zoxinano lwamandla amandla eebhetri ze-lithium-ion zibophelelekile ukuqhubeka nokukhuthaza ukuguqulwa kweemodeli zebhetri ze-lithium-ion.

Ngokolwazi oluvezwe nguTesla ekuqaleni kwalo nyaka, phantsi kweemeko zangoku, ubuninzi bamandla benkqubo yebhetri ye-21700 malunga ne-300Wh / kg, malunga ne-20% ephezulu kune-250Wh / kg yenkqubo yebhetri ye-18650 yokuqala. Ukunyuka komthamo webhetri kuthetha ukuba inani leeseli ezifunekayo kumandla afanayo lincitshiswa malunga ne-1/3, enciphisa ubunzima bolawulo lwenkqubo kwaye ilula inani lezixhobo ezifana nezakhiwo zetsimbi, nangona ubunzima kunye neendleko zomntu omnye. iseli ziye zanda , Kodwa ubunzima kunye neendleko zenkqubo yebhetri ye-PACK zincitshisiwe.

Ukuveliswa kobu buchwepheshe obutsha bokuzihlukanisa kuvumela ibhetri ye-21700 ye-cylindrical ene-enence yamandla ephezulu ukuba igcinwe kakuhle ngokwemiqathango yokuzinza kwe-thermal.

Izimvo: Ngokweebhetri zecylindrical, iinkampani zebhetri zaseTshayina ziseninzi ekufuneka zifunde kwiPanasonic yaseJapan. Okwangoku, i-BAK, i-Yiwei Lithium Energy, i-Smart Energy kunye ne-Suzhou Lishen zonke zisebenzise i-21700 yeemveliso zebhetri. Ukuguqulwa komgca wokuvelisa ikakhulu kubandakanya ukusika, ukujija, ukudibanisa, ukwenza kunye nezinye izixhumanisi zamanqanaba aphakathi kunye nasemva, kunye neendleko zokulungiswa kwe-mold kumgca we-semi-automatic iphantsi. Kukulungele ngakumbi ukuba abavelisi beebhetri batshintshe ukusuka kwi-18650 yesiqhelo ukuya kwi-21700, kwaye abayi kutyala imali ephezulu kakhulu yeendleko zenguqu yobugcisa kunye notyalo-mali olutsha lwezixhobo. Nangona kunjalo, iinkampani zeemoto zelizwe lam zisalela emva kweTesla ngokwetekhnoloji yolawulo lwebhetri, kwaye mininzi kakhulu imisebenzi yasekhaya ekufuneka yenziwe.
