I-Chalmers University kanye ne-KTH badale ibhondi yesakhiwo eguquguqukayo. Ukuminyana kwamandla aphansi, kodwa kukhona amandla

Izakhi zesakhiwo ziyithrendi entsha ekukhiqizeni ibhethri. Izinto kuze kube manje ezaziyi-ballast kuphela ziguqulwa zibe izakhi ezisebenza njengesisekelo sebhethri noma ngisho nemoto. Futhi kungale ndlela lapho ososayensi abavela emanyuvesi amabili ezobuchwepheshe aziwayo aseSweden alandele: Inyuvesi yaseChalmers kanye neRoyal Institute of Technology (KTH).

Amabhondi esakhiwo aguqukayo ngenxa yezinhlanganisela. 0,024 kWh / kg manje, izinhlelo zingu-0,075 kWh / kg

Izibopho zesakhiwo ngezinye izikhathi zibizwa ngokuthi "massless", kodwa leli gama akufanele lithathwe njengoba linjalo ngomqondo owuphawu lwefiziksi yezinhlayiyana eziyisisekelo. Amaseli "angenasisindo" emotweni amangqamuzana angewona ama-ballast angeziwe ngoba asebenza njengamathambo, ama-reinforcements, njll. - izakhiwo ezibalulekile emotweni.

Idalwe yi-Chalmers University kanye ne-KTH, amaseli aqukethe ama-electrode amabili: i-carbon fibre (anode) ne-lithium iron phosphate (cathode), phakathi kwayo kukhona i-glass fiber material egcwele i-electrolyte. Uma sibheka okuqoshiwe, singasho ukuthi konke lokhu kuqoqwe emzimbeni owodwa oyinhlanganisela:

Le yindlela isixhumanisi esenziwa ngayo nokunwebeka futhi ngiphezu kwama-electrode amandla 8,4 volts (3x 2,8V). Ososayensi bayavuma ukuthi sebekuzuzile ukuminyana kwamandla manje 0,024 kWh / kg, engaphansi izikhathi ezingaphezu kweshumi kunamabhethri anamuhla angcono kakhulu (0,25-0,3 kWh / kg). Kodwa-ke, uma sikhumbula ukuthi ngezakhi zakudala kuyadingeka ukwengeza isisindo samamojula kanye necala lebhethri, umehluko uba "kuphela" izikhathi ezingu-6-8.

Imojuli encanei-modulus yokunwebeka kwesixhumanisi sesakhiwo se-prototype yi ngaphezu kwe-28 GPA... Ukuze uqhathanise: ipulasitiki, eqiniswe nge-carbon fiber, ine-modulus ye-Young engu-30-50 GPa, ngakho-ke iseli le-Chalmers University kanye ne-KTH awahlukani kakhulu nozakwabo wakudala.

Ososayensi bafuna Yehlisa usayizi wesihlukanisi esinyathelweni esilandelayo bese ubuyisela ucwecwe lwe-aluminium ku-electrode nge-carbon fiber material. Kucatshangwa ukuthi, ngenxa yalezi ntuthuko, zizofinyelela izinga lika-0,075 kWh / kg no-75 GPa.... Futhi ngisho noma lezi zinhlobo zamaseli zibiza kakhulu ukuze zisetshenziswe ezimotweni, zingasebenza kahle, isibonelo, ezindizeni.

Imoto yokuqala enesixhumanisi esakhayo kwakuyi-BYD Han yaseShayina. Kulo nyaka zizovela noma zizovela ku-BYD Tang (2021), Mercedes EQS noma i-Tesla Model Y, eyenziwe eJalimane futhi isekelwe ezintweni ezingu-4680.
