Mabatire a asphalt anali abwino, koma konkriti / simenti-ion ndiyabwinoko. Kumanga ngati sitolo yamagetsi

Zaka zoposa ziwiri zapitazo, tidalongosola momwe asphalt yachilengedwe ingawonjezere mphamvu ya batri ya lithiamu-ion. Tsopano pali pempho la zinthu zina zomwe timakumana nazo tsiku lililonse. Ofufuza ku Chalmers University of Technology ku Sweden amawona lingaliro la konkriti ngati batire yayikulu. Ndipo ali kale ndi chitsanzo cha batire ya simenti.

"Mulingo wa batri pa block ndi 27 peresenti. Kutsegula"

Lingaliro ndi losavuta: tiyeni titembenuzire zinthu zomwe zimatizungulira kukhala mabatire kuti tisunge mphamvu mwa izo tikakhala nazo zochuluka. Izi nzosavuta kunena kuposa kuchita. Chifukwa chake, asayansi ku Yunivesite ya Chalmers adaganiza zopanga maselo opangidwa ndi simenti. Anode Wopangidwa ndi Nickel Plated Carbon Fiber Mesh. Cathode ndiwo maukonde omwewo, koma wokutidwa ndi chitsulo; Ma grating onsewo adayikidwa mu simenti yopangidwa ndi magetsi yopangidwa ndi simenti yophatikizidwa ndi ulusi wamfupi wa carbon.

Selo lachiwonetsero lili pano ndipo limagwira ntchito mu labotale.pachithunzi choyambirira, imapatsa mphamvu diode (gwero). Kachulukidwe mphamvu si mopitirira muyeso monga 0,0008 kWh / l (0,8 Wh / l) kapena 0,007 kWh / mXNUMX.²... Poyerekeza: Ma cell a lithiamu-ion amakono amapereka mawatt mazana angapo pa lita imodzi (Wh / l), yomwe ndi nthawi mazana ambiri.. Koma ili ndi vuto laling'ono, chifukwa midadada ya simenti (konkire) ndi nyumba za mazana a cubic metres.

Batire ya simenti, yopangidwa ndi asayansi ku yunivesite ya Chalmers, imakhala yamphamvu kuwirikiza kakhumi kuposa machitidwe am'mbuyomu. Chofunika kwambiri, imatha kulipiritsidwa ndikutulutsidwa kangapo. Ochita kafukufuku ndi osamala: ngakhale zili za ma diode amagetsi, masensa ang'onoang'ono kapena njira zowunikira magalimoto pamisewu ndi milatho. Koma saona zolepheretsa m’tsogolo kugwiritsa ntchito magilodi a electrode m’nyumba zazikulu, motero kuwasandutsa zipangizo zazikulu zosungiramo mphamvu.

Pakalipano, vuto lalikulu ndi kupanga maselo m'njira yoti azikhala nthawi yaitali ngati nyumba za konkire, ndiko kuti, zaka 50-100. Ngati izi sizikutheka, kusintha kwawo ndi kubwezeretsanso kuyenera kukhala kosavuta kotero kuti kubwezeretsanso mphamvu ya nyumbayo ngati malo osungiramo mphamvu sikufuna kugwetsa ndi kukonzanso.

Izi zingakusangalatseni:
