Chalmers University ndi KTH apanga ulalo wosinthika wosinthika. Low mphamvu kachulukidwe, koma kuthekera
Zomangamanga ndi njira yatsopano yopangira batri. Zinthu zomwe mpaka pano zinali za ballast zokha zimasinthidwa kukhala zinthu zomwe zimakhala ngati maziko a batri kapena galimoto. Ndipo ndi mbali iyi yomwe asayansi ochokera ku mayunivesite awiri odziwika bwino aukadaulo aku Sweden atsatira: Chalmers University ndi Royal Institute of Technology (KTH).
Zomangira zosinthika chifukwa cha ma kompositi. 0,024 kWh / kg tsopano, mapulani ndi 0,075 kWh / kg
Zomangira zomangika nthawi zina zimatchedwa "massless", koma mawuwa sayenera kutengedwa momwemo m'lingaliro lomwe liri ndi chikhalidwe cha pulayimale particle physics. "Misa" maselo m'galimoto ndi chabe maselo amene si owonjezera ballast chifukwa amachita monga mafupa, reinforcements, etc. - zofunika nyumba galimoto.
Wopangidwa ndi Chalmers University ndi KTH, maselowa amakhala ndi maelekitirodi awiri: kaboni CHIKWANGWANI (anode) ndi lithiamu chitsulo mankwala (cathode), pakati pa zomwe ndi galasi CHIKWANGWANI chuma zokhutitsidwa ndi electrolyte. Kuyang'ana kujambula, tinganene kuti zonsezi zimasonkhanitsidwa mu gulu limodzi lophatikizana:
Umu ndi momwe ulalo umapangidwira zotanuka ndipo ndili pa ma electrode voteji 8,4 volts (3x 2,8V). Asayansi amavomereza kuti akwanitsa kachulukidwe mphamvu сейчас 0,024 kWh / kg, yomwe imakhala yocheperapo kuposa nthawi khumi kuposa mabatire amakono (0,25-0,3 kWh / kg). Komabe, ngati tikumbukira kuti ndi zinthu zakale ndi zofunika kuwonjezera kulemera kwa ma modules ndi batire mlandu, kusiyana kumakhala "kokha" 6-8.
Junior modulemodulus wa elasticity wa structural ulalo wa prototype ndi kuposa 28 GPA... Poyerekeza: pulasitiki, yolimbikitsidwa ndi carbon fiber, imakhala ndi Young modulus ya 30-50 GPa, kotero selo la yunivesite ya Chalmers ndi KTH silisiyana kwambiri ndi mnzake wakale.
Asayansi akufuna Chepetsani kukula kwa cholekanitsa mu sitepe yotsatira ndikusintha zojambulazo za aluminiyamu pa electrode ndi zinthu za carbon fiber. Zimaganiziridwa kuti, chifukwa cha kusintha kumeneku, zidzafika pamlingo wa 0,075 kWh / kg ndi 75 GPa.... Ndipo ngakhale maselo amtunduwu ndi okwera mtengo kwambiri kuti asagwiritsidwe ntchito pamagalimoto, amatha kugwira ntchito bwino, mwachitsanzo, paulendo wandege.
Galimoto yoyamba yokhala ndi ulalo wothandiza inali yaku China BYD Han. Chaka chino iwo adzawoneka kapena adzawonekera mu BYD Tang (2021), Mercedes EQS kapena Tesla Model Y, yopangidwa ku Germany ndipo imachokera ku zinthu za 4680.
