Sekureva kwemishumo yenhau dzekunze, Tesla nguva pfupi yadarika akanyorera patent nyowani yekuparadzanisa maseru akaremara ebhatiri kuti adzivise kukanganisa masero anoshanda ebhatiri, nekudaro achivandudza kuchengetedza kwebhatiri.

Mamiriro ekusimudzirwa kwaTesla kweiyi patent ndeyekuti nekuti masero ebhatiri anoburitsa kupisa panguva yekuchaja uye kana aburitsa simba, Tesla akaona kuti akaremara bhatiri maseru anoburitsa kupisa, izvo zvinokanganisa mashandiro emasero akatenderedza bhatiri. Zvinokonzera kuramba kukundikana kwebhatiri. Naizvozvo, yakagadzira patent.

Iyo Tesla patent inodonongodza sisitimu yakaoma inogadzira iyo yekubatanidza layer (inter-yekubatanidza layer) inotarisisa uye inogadzirisa tembiricha uye kudzvanywa mubhatiri paki nekutsaura zvinhu zvisina kunaka.

Iyo Tesla Model 3 yakashongedzerwa neazvino chizvarwa chemabhatiri, 21700 bhatiri maseru. Tesla yakaratidza kuti bhatiri sero rine simba repamusoro kupfuura chero yemagetsi bhatiri sero nekuti inoderedza zvakanyanya cobalt yemukati, inowedzera zvine simba iyo nickel yemukati, uye bhatiri system inochengetedza kugadzikana kwese kwekushisa. Tesla akataurawo kuti kemikari yenickel-cobalt-aluminium yakanaka electrode yeTesla bhatiri cell yakaderera pane zviri mubhatiri yechizvarwa chinotevera chemukwikwidzi.

Tesla’s patent nyowani zvakare inoratidza kuti kunyangwe hutungamiriri hwekambani mune tekinoroji yebhatiri, ichiri kutyaira hunyanzvi.

Chii chinonzi mashiripiti e21700?

Musiyano wakanyanya kunzwisisika pakati pe21700 ne18650 mabhatiri ndiko kukura kwakakura.

Nekuda kwekudzikiswa kwekuita kwebhatiri, kuwedzera simba remagetsi nekuwedzera vhoriyamu nyowani yave chinhu chakakosha kufunga kukambani. nyika yangu inonyatso kurudzira kuti muna 2020, simba remagetsi emagetsi lithium-ion bhatiri masero richapfuura 300Wh / kg, uye simba remagetsi emagetsi lithium-ion battery systems richasvika 260Wh / kg; muna 2025, iyo simba density yesimba lithium-ion bhatiri masisitimu ichasvika 350Wh/kg. Izvo zvinoramba zvichiwedzera simba density zvinodiwa zvemagetsi lithium-ion mabhatiri anosungirwa kuenderera mberi nekusimudzira shanduko yelithium-ion bhatiri modhi.

Zvinoenderana neruzivo rwakaziviswa naTesla mukutanga kwegore rino, pasi pemamiriro azvino, simba remagetsi eiyo 21700 bhatiri system rinenge 300Wh/kg, iyo inenge 20% yakakwirira kupfuura 250Wh/kg yeyayo yekutanga 18650 bhatiri system. Kuwedzera kwehuwandu hwebhatiri kunoreva kuti huwandu hwemasero anodiwa kune simba rimwechete hunodzikiswa neinenge 1/3, izvo zvinoderedza kuoma kwehurongwa hwekutonga uye kurerutsa huwandu hwezvishandiso senge simbi zvimiro, kunyangwe huremu uye mutengo weimwe chete. sero rawedzera , Asi huremu uye mutengo webhatiri system PACK zvaderedzwa.

Kugadzirwa kweiyi tekinoroji nyowani yekuzviparadzanisa nevamwe inobvumira iyo 21700 cylindrical bhatiri ine yakakwirira simba density kuti ichengetedzwe zvakanaka maererano nekugadzikana kwekupisa.

Mhinduro: Panyaya yemabhatiri ecylindrical, makambani ebhatiri eChinese achine zvakawanda zvekudzidza kubva kuPanasonic yekuJapan. Parizvino, BAK, Yiwei Lithium Energy, Smart Energy uye Suzhou Lishen vese vakaisa 21700 zvigadzirwa zvebhatiri. Iko kushandurwa kwemutsara wekugadzira kunonyanya kusanganisa kucheka, kupeta, kuunganidza, kuumba uye zvimwe zvinongedzo zvepakati uye gare gare nhanho, uye mutengo wekugadzirisa mold kune semi-otomatiki mutsara wakaderera. Izvo zviri nyore kune vanogadzira mabhatiri kuti vashanduke kubva kune yekutanga mainstream 18650 kuenda 21700, uye ivo havazodyara yakakwira michina yekuchinja mutengo uye mitsva yekushandisa mari. Nekudaro, makambani emotokari emunyika yangu anosaririra kumashure kweTesla maererano nehunyanzvi hwekutarisira bhatiri, uye kune basa remumba rakawandisa rekugadzira.
