Chalmers University thiab KTH tau tsim ib daim ntawv cog lus hloov tau. Tsawg zog ceev, tab sis muaj peev xwm

Cov ntsiab lus ntawm cov qauv yog ib qho kev hloov tshiab hauv kev tsim cov roj teeb. Cov ntsiab lus uas kom txog rau thaum tam sim no tsuas yog ballast tau hloov mus rau hauv cov ntsiab lus uas ua lub hauv paus ntawm lub roj teeb lossis txawm tias lub tsheb. Thiab nws yog nyob rau hauv cov kev taw qhia no uas cov kws tshawb fawb los ntawm ob lub npe nrov Swedish universities ntawm technology tau ua raws li: Chalmers University thiab Royal Institute of Technology (KTH).

Saj zawg zog structural bonds ua tsaug rau composites. 0,024 kWh / kg tam sim no, kev npaj yog 0,075 kWh / kg

Cov qauv kev sib raug zoo qee zaum hu ua "massless", tab sis cov lus no yuav tsum tsis txhob raug coj los ntawm qhov kev nkag siab uas yog tus yam ntxwv ntawm lub cev particle physics. "Massless" hlwb nyob rau hauv ib lub tsheb tsuas yog cov hlwb uas tsis ntxiv ballast vim hais tias lawv ua raws li cov pob txha, kev txhawb zog, thiab lwm yam - cov qauv tseem ceeb hauv lub tsheb.

Tsim los ntawm Chalmers University thiab KTH, lub hlwb muaj ob lub electrodes: carbon fiber (anode) thiab lithium hlau phosphate (cathode), ntawm uas yog cov iav fiber ntau saturated nrog electrolyte. Saib ntawm cov ntaubntawv povthawj siv, peb tuaj yeem hais tias tag nrho cov no tau sau rau hauv ib lub cev sib xyaw:

Qhov no yog li cas qhov txuas yog tsim elastic thiab kuv nyob ntawm electrodes zog 8,4v 3 x 2,8V. Cov kws tshawb fawb lees tias lawv tau ua tiav zog ceev txoj cai tam sim no 0,024 kWh / kg, uas yog ntau tshaj kaum npaug qis dua hauv cov roj teeb zoo tshaj plaws niaj hnub no (0,25-0,3 kWh / kg). Txawm li cas los xij, yog tias peb nco qab tias nrog cov ntsiab lus classic nws yog qhov tsim nyog los ntxiv qhov hnyav ntawm cov qauv thiab cov ntaub ntawv roj teeb, qhov sib txawv ua "tsuas yog" 6-8 zaug.

Junior modulelub modulus ntawm elasticity ntawm cov qauv txuas ntawm tus qauv yog ntau tshaj 28 GPa... Rau kev sib piv: yas, reinforced nrog carbon fiber, muaj ib tug Young's modulus ntawm 30-50 GPa, yog li lub cell ntawm Chalmers University thiab KTH tsis txawv ntau ntawm nws classical counterpart.

Cov kws tshawb fawb xav tau Txo qhov loj ntawm qhov sib cais hauv cov kauj ruam tom ntej thiab hloov cov ntawv txhuas ntawm cov electrode nrog cov khoom siv carbon fiber. Nws tau xav tias, ua tsaug rau cov kev txhim kho no, lawv yuav ncav cuag qib 0,075 kWh / kg thiab 75 GPa.... Thiab txawm tias cov hom cell no kim heev rau kev siv hauv tsheb, lawv tuaj yeem ua haujlwm tau zoo, piv txwv li, hauv aviation.

Thawj lub tsheb nrog kev sib txuas lus yog Suav BYD Han. Xyoo no lawv yuav lossis yuav tshwm sim hauv BYD Tang (2021), Mercedes EQS lossis Tesla Model Y, ua hauv Tebchaws Yelemees thiab raws li 4680 lub ntsiab lus.
