Chalmers University neKTH vakagadzira chinochinjika chisungo chisungo. Low simba density, asi pane zvinogona

Zvimiro zvinhu maitiro matsva mukugadzirwa kwebhatiri. Zvinhu izvo kusvika zvino zvaingova ballast zvinoshandurwa kuita zvinhu zvinoshanda sehwaro hwebhatiri kana kunyange mota. Uye iri munzira iyi kuti masayendisiti kubva kumayunivhesiti maviri anozivikanwa eSweden tekinoroji akatevera: Chalmers University uye Royal Institute of Technology (KTH).

Flexible structural bonds nekuda kwecomposites. 0,024 kWh/kg ikozvino, 0,075 kWh/kg zvirongwa

Zvisungo zvisungo dzimwe nguva zvinodaidzwa kuti "zvisingaverengeki", asi izwi iri harifanirwe kutorwa sezvariri mupfungwa iyo inofananidzira yekutanga particle physics. "Massless" masero mumotokari angori masero asiri ekuwedzera ballast nekuti anoita semarango, anosimbisa, nezvimwe - zvakakosha zvimiro mumotokari.

Yakagadzirwa neChalmers University neKTH, masero acho ane ma electrode maviri, kabhoni fiber (anode) uye lithium iron phosphate (cathode), pakati peiyo girazi fiber material yakazara ne electrolyte. Tichitarisa kurekodha, tinogona kutaura kuti izvi zvese zvinounganidzwa mune imwe kesi yemakompositi:

Aya ndiwo magadzirirwo akaitwa chinongedzo. elastic uye ini pamagetsi voltage 8,4 volts (3x 2,8V). Nyanzvi dzinobvuma kuti dzakadaro simba density сейчас 0,024 kWh / kg, iyo inopfuura kagumi yakaderera kupfuura mumabhatiri akanakisa emazuva ano (0,25-0,3 kWh / kg). Zvisinei, kana tikayeuka kuti nezvinhu zvekare zvakakosha kuwedzera uremu hwema modules uye bhatiri kesi, mutsauko unova "chete" 6-8 nguva.

Module yevadikiiyo modulus ye elasticity yeiyo structural link ye prototype yakaenzana ne pamusoro pe28 GPA. Mukuenzanisa, kabhoni faibha yakasimbiswa purasitiki ine Yechidiki modulus ye30-50 GPa, saka iyo Chalmers University neKTH cell haina kusiyana zvakanyanya kubva kune yayo yekare yekare.

Masayendisiti anoda Deredza saizi yekuparadzanisa mudanho rinotevera uye kutsiva iyo aluminium foil pane electrode nekabhoni fiber zvinhu. Zvinofungidzirwa kuti nekuda kwekuvandudzwa uku, ivo vachasvika pamwero we0,075 kWh / kg uye 75 GPa.. Uye kunyange kana aya marudzi emasero akadhura zvakanyanya kuti asashandiswa mumotokari, anogona kushanda zvakanaka mundege, semuenzaniso.

Motokari yekutanga ine dhizaini yekubatanidza yaive yeChinese BYD Han. Gore rino ivo vachaonekwa kana kuoneka muBYD Tang (2021), Mercedes EQS kana Tesla Model Y yakagadzirwa muGermany uye yakavakirwa pane 4680 zvinhu.
