Alise Project: Ma cell athu a lithiamu sulfure afika 0,325 kWh / kg, tikupita 0,5 kWh / kg

Alise Project ndi ntchito yofufuza yothandizidwa ndi European Union, yophatikiza makampani ndi mabungwe 16 ochokera kumayiko asanu. Asayansi amangodzitama kuti adapanga selo ya Li-S (lithium-sulfur) yokhala ndi mphamvu zokwana 5 kWh/kg. Ma cell a lithiamu-ion abwino kwambiri omwe akugwiritsidwa ntchito pano amafika mpaka 0,325 kWh/kg.

Zamkatimu

• Kuchulukana kwakukulu = kuchuluka kwa batri
  • Li-S m'galimoto: yotsika mtengo, mwachangu, mopitilira. Koma osati tsopano

Kuchuluka kwa mphamvu kwa selo kumatanthauza kuti imatha kusunga mphamvu zambiri. Mphamvu zowonjezera pa unit mass ndi mwina magalimoto apamwamba amagetsi (posunga kukula kwa batri), kapena ayi mayendedwe apano okhala ndi mabatire ang'onoang'ono komanso opepuka. Kaya tikuyenda bwanji, zinthu zimatikomera nthawi zonse.

Lithium-sulfure element ndi chinthu chofunikira kwambiri pakufufuza zikafika pakuchulukira kwa mphamvu pa unit kuchuluka kwa zinthu. Lithiamu ndi sulfure ndi zinthu zopepuka, kotero kuti chinthucho sichilemera. Ntchito ya Alise idakwanitsa 0,325 kWh/kg, zomwe ndi pafupifupi 11 peresenti kuposa zomwe CATL yaku China imanena m'maselo ake a lithiamu-ion:

> CATL imadzitamandira kuti ikuphwanya chotchinga cha 0,3 kWh/kg pama cell a lithiamu-ion

Mmodzi mwa mamembala a Alise Project, Oxis Energy, adalonjeza kale kuti adzakhala ndi 0,425 kWh / kg, koma mu polojekiti ya EU, asayansi adaganiza zochepetsera kachulukidwe kuti akwaniritse, mwa zina: mphamvu zowonjezera zowonjezera. Komabe, pomaliza amafuna kusuntha kufika ku 0,5 kWh/kg (gwero).

Batire imatengera ma module odzazidwa ndi ma cell a Li-S (c) Alise Project.

Li-S m'galimoto: yotsika mtengo, mwachangu, mopitilira. Koma osati tsopano

Maselo ozikidwa pa lithiamu ndi sulfure amawoneka odalirika, koma chidwicho chikuzimiririka. Iwo amakukumbutsani kuti padakali mtunda wautali. Mwachitsanzo Mabatire a Li-S pakadali pano amapirira pafupifupi ma 100 otulutsa.pomwe maulendo a 800-1 amaonedwa kuti ndi ocheperako masiku ano, ndipo pali kale ma prototypes omwe amalonjeza kuzungulira kwa 000-3:

> Labu ya Tesla ili ndi ma cell omwe amatha kupirira makilomita mamiliyoni [Electrek]

Kutentha kulinso vuto. pamwamba pa madigiri 40 Celsius, zinthu za Li-S zimawola msanga. Ofufuzawo akufuna kukweza gawoli mpaka madigiri 70, kutentha komwe kumachitika ndi kulipiritsa mwachangu kwambiri.

Komabe, pali chinachake chomenyera nkhondo, chifukwa mtundu uwu wa selo sufuna mtengo, wovuta kupeza cobalt, koma lifiyamu yotsika mtengo komanso sulfure yopezeka mosavuta. Komanso, ongoyerekeza mphamvu kachulukidwe sulfure ndi 2,6 kWh/kg - pafupifupi kakhumi kuposa maselo abwino lithiamu-ion anayambitsa lero.
