I-Stanford: Sehlise isisindo sabaqoqi bamanje kumaseli e-lithium-ion ngamaphesenti angu-80. Ukuminyana kwamandla kukhuphuka ngamaphesenti ayi-16-26.

Ososayensi base-Stanford University kanye ne-Stanford Linear Accelerator Centre (SLAC) banqume ukushwabanisa amaseli e-lithium-ion ukuze ehlise isisindo sawo futhi ngaleyo ndlela andise ukuminyana kwamandla agciniwe. Ukuze benze lokhu, baphinde balungisa izingqimba ezithwala imithwalo ngaphandle: esikhundleni samashidi abanzi ethusi noma i-aluminium, basebenzisa imicu emincane yensimbi, ehlanganiswe nongqimba lwe-polymer.

Ukuminyana kwamandla okuphezulu ku-Li-ion ngaphandle kwezindleko eziphezulu zokutshala imali

Iseli ngalinye le-Li-ion liwumqulu ohlanganisa ungqimba lokushaja/lokukhipha, i-electrode, i-electrolyte, i-electrode, kanye nomqoqi wamanje ngalolo hlelo. Izingxenye ezingaphandle ziyi-foil yensimbi eyenziwe ngethusi noma nge-aluminium. Avumela ama-electron ukuba ashiye ingqamuzana abuyele kulo.

Ososayensi abavela e-Stanford nase-SLAC banquma ukugxila kubaqoqi, ngoba isisindo sabo ngokuvamile singamashumi amaningana amaphesenti esisindo sesixhumanisi sonke. Esikhundleni samashidi ethusi, basebenzisa amafilimu e-polymer anemicu yethusi emincane. Kwavela ukuthi kungenzeka ukunciphisa isisindo sabaqoqi ngamaphesenti angama-80:

Iseli ye-lithium-ion yakudala eyi-cylindrical ingumqulu omude ohlanganisa izendlalelo ezimbalwa. Ososayensi abavela e-Stanford kanye ne-SLAC banciphise izendlalelo eziqoqa izindleko futhi baziqhube - abaqoqi bamanje. Esikhundleni samashidi ethusi, basebenzise amashidi e-polymer-copper anothiswe ngamakhemikhali angashi (c) Yusheng Ye / Stanford University

Akugcini lapho: ama-chemical compounds angangezwa ku-polymer evimbela ukuthungela, bese ukuvutha okuphansi kwezinto kuhambisana nesisindo esincane:

Ukuvutha kwe-foil yethusi esetshenziswa kuseli ye-lithium-ion yakudala kanye nomqoqi othuthukiswe abacwaningi baseMelika (c) Yusheng E / Stanford University

Abacwaningi bathi abaqoqi abagaywe kabusha bangakhuphula ukuminyana kwamandla adonsela phansi amaseli ngamaphesenti angu-16-26 (= amaphesenti angu-16-26 engeziwe kuyunithi efanayo yesisindo). Kusho ukuthi ibhethri elinosayizi ofanayo kanye nokuminyana kwamandla kungaba lula ngo-20% kunamanje.

Imizamo yenziwe esikhathini esedlule yokuthuthukisa ichibi, kodwa ukulishintsha kuholele emiphumeleni engemihle engalindelekile. Amaseli awazange azinze noma kudingeke i-electrolyte [ebiza kakhulu]. Okuhlukile okuthuthukiswe ososayensi eStanford akubonakali kubangela izinkinga ezinjalo.

Lokhu kuthuthukiswa kusekucwaningweni lwangaphambi kwesikhathi, ngakho-ke ungalindeli ukuthi zifike emakethe ngaphambi kuka-2023. Nokho, zibukeka zithembisa.

Kufanele kwengezwe ukuthi uTesla naye unombono othakazelisayo wokuqoqa ukukhokhiswa kwezingqimba zensimbi. Esikhundleni sokusebenzisa imicu yethusi emincane kubo bonke ubude bomqulu futhi uyikhiphe endaweni eyodwa kuphela (phakathi), iwakhipha ngokushesha kusetshenziswa unqenqema olusikiwe olugqagqene. Lokhu kwenza izindleko zihambe ibanga elincane kakhulu (ukumelana!), Futhi ithusi lihlinzeka ngokudluliswa kokushisa okwengeziwe ngaphandle:
