Kafukufuku watsopano wochokera ku University College London ndi University of Oxford akuwonetsa kuti ngakhale mabatire a lithiamu-ion mu ndudu zotayidwa za e-fodya amatayidwa atagwiritsidwa ntchito kamodzi, amatha kukhalabe ndi mphamvu zambiri pakadutsa mazana ambiri.Kafukufukuyu adathandizidwa ndi Faraday Institute ndipo adasindikizidwa mu nyuzipepala ya Joule.
Kutchuka kwandudu zotayidwachakwera kwambiri ku UK kuyambira 2021, kafukufuku yemwe adapeza kuti kutchuka kwa ndudu zotayidwa kwakula mowirikiza 18 pakati pa Januware 2021 ndi Epulo 2022, zomwe zidapangitsa kuti Mamiliyoni a zida zilizonse zotayidwa zimatayidwa sabata iliyonse.
Gulu lofufuza linali ndi lingaliro lakuti mabatire omwe amagwiritsidwa ntchito mu ndudu za e-fodya anali okhoza kuwonjezeredwa, koma palibe maphunziro apambuyo omwe adayesa moyo wa batri wa mabatire a lithiamu-ion muzinthuzi.
“Ndudu zotayidwazatchuka kwambiri m'zaka zaposachedwapa.Ngakhale amagulitsidwa ngati zinthu zotayidwa, kafukufuku wathu akuwonetsa kuti mabatire a lithiamu-ion omwe amasungidwa mkati mwake amatha kulipiritsidwa ndikutulutsidwa nthawi zopitilira 450.Kafukufukuyu akuwonetsa momwe kutsekemera kumodzi kumawonongera chuma chochepa, "anatero Hamish Reid, mlembi wamkulu wa kafukufuku ku School of Chemical Engineering, University College London.
Pofuna kuyesa malingaliro awo, ofufuza ochokera ku University College London ndi University of Oxford anatola mabatire kuchokera ku zotayidwae-ndudupansi pamikhalidwe yoyendetsedwa ndikuwayesa pogwiritsa ntchito zida ndi njira zomwe zimagwiritsidwa ntchito pophunzira mabatire m'magalimoto amagetsi ndi zida zina..
Anayang'ana batire pansi pa maikulosikopu ndipo adagwiritsa ntchito X-ray tomography kuti afotokoze momwe mkati mwake amapangidwira ndikumvetsetsa zida zake.Mwa kulipiritsa ndi kutulutsa ma cell mobwerezabwereza, amazindikira momwe ma cell amasungirira mphamvu zawo zama electrochemical pakapita nthawi, ndikupeza kuti nthawi zina amatha kuwonjezeredwa kambirimbiri.
Pulofesa Paul Shearing, mlembi wamkulu wa pepalalo kuchokera ku UCL's School of Chemical Engineering ndi University of Oxford, anati: “Chodabwitsa n’chakuti zotsatira zasonyeza kuti mabatire amenewa amatenga nthawi yaitali bwanji.Ngati mumagwiritsa ntchito zotsika mtengo komanso zotulutsa, mutha kuwona Chifukwa chake, pakadutsa mizunguliro yopitilira 700, kusungitsa mphamvu kumapitilira 90%.Ndipotu, iyi ndi batri yabwino kwambiri.Amangotayidwa ndikuponyedwa mwachisawawa m’mphepete mwa msewu.”
“Pang'ono ndi pang'ono, anthu akuyenera kumvetsetsa mitundu ya mabatire omwe amagwiritsidwa ntchito pazidazi komanso kufunika kotaya moyenera.Opanga akuyenera kupereka dongosolo la chilengedwee-fodya kugwiritsanso ntchito batri ndikubwezeretsanso, komanso kuyenera kupanga zida zongowonjezeranso kukhala zosakhazikika. ”
Pulofesa Shearing ndi gulu lake akufufuzanso njira zatsopano zobwezeretsanso batire zomwe zimatha kukonzanso zinthu zilizonse popanda kuipitsidwa, komanso ma batri okhazikika, kuphatikiza mabatire a lithiamu-ion, mabatire a Lithium-sulfure ndi mabatire a sodium-ion. .Kuti athane ndi zovuta pazantchito zonse za batire, asayansi akuyenera kuganizira za moyo wa batri akamaganizira kugwiritsa ntchito mabatire aliwonse.
