European project LISA tab tom yuav pib. Lub hom phiaj tseem ceeb: tsim cov roj teeb lithium-sulfur nrog qhov ceev ntawm 0,6 kWh / kg
Raws nraim thaum Lub Ib Hlis 1, 2019, European project LISA pib, lub hom phiaj tseem ceeb uas yuav yog kev loj hlob ntawm Li-S (lithium-sulfur) hlwb. Vim yog cov khoom ntawm leej faj, uas yog sib zog dua cov hlau siv niaj hnub no, lithium sulfur hlwb tuaj yeem ncav cuag lub zog tshwj xeeb ntawm 0,6 kWh / kg. Qhov zoo tshaj plaws niaj hnub lithium-ion hlwb niaj hnub no yog nyob ib ncig ntawm 0,25 kWh / kg.
Cov txheej txheem
- Lithium-Sulfur Cells: Lub neej yav tom ntej ntawm tsheb, dav hlau thiab tsheb kauj vab
- LISA project: high-density thiab pheej yig lithium-polymer roj teeb nrog cov khoom electrolyte.
Cov kws tshawb fawb ua haujlwm ntawm cov hluav taws xob hluav taws xob tau sim ntau lub hlwb lithium sulfur rau ntau xyoo. Lawv lub peev xwm yog qhov zoo heev vim lawv cog lus theoretical Lub zog tshwj xeeb 2,6 kWh / kg (!). Tib lub sijhawm, leej faj yog cov khoom pheej yig thiab siv tau vim nws yog cov khoom pov tseg los ntawm cov chaw tsim hluav taws xob thee.
Hmoov tsis, sulfur kuj muaj qhov tsis zoo: Txawm hais tias nws tau lees tias qhov hnyav ntawm tes - yog vim li cas Li-S hlwb tau siv hauv lub dav hlau hluav taws xob, rhuav tshem cov ntaub ntawv davhlau tsis nres - nws cov khoom siv tshuaj lom neeg ua rau nws zoo heev. dissolves sai sai hauv electrolyte... Hauv lwm lo lus: Lub roj teeb Li-S muaj peev xwm khaws cia cov nqi loj hauv ib chav tsev, tab sis thaum lub sijhawm ua haujlwm nws raug rhuav tshem tsis tau..
> Rivian lub roj teeb siv 21700 hlwb - zoo li Tesla Model 3, tab sis tej zaum LG Chem ib yam nkaus.
LISA project: high-density thiab pheej yig lithium-polymer roj teeb nrog cov khoom electrolyte.
LISA (lithium sulfur rau txoj kev nyab xeeb hluav taws xob) qhov project yuav tsum kav ntev tshaj li 3,5 xyoo. Nws tau koom tes nrog nyiaj txiag ntawm 7,9 lab euros, uas yog sib npaug rau kwv yees li 34 lab zlotys. Nws tau koom nrog Oxis Zog, Renault, Varta Micro Battery, Fraunhofer Institute thiab Dresden University of Technology.
Txoj haujlwm LISA lub hom phiaj los tsim Li-S cov hlwb nrog cov khoom siv hluav taws xob uas tsis yog hluav taws xob hybrid. Nws yog ib qho tsim nyog los daws qhov teeb meem ntawm kev tiv thaiv cov electrodes, uas ua rau cov cell degradation sai. Cov kws tshawb fawb hais tias los ntawm qhov theoretical zog ceev ntawm 2,6 kWh / kg, 0,6 kWh / kg tuaj yeem tau txais tiag tiag.
> Asphalt (!) yuav ua rau kom muaj peev xwm thiab ua kom lub zog ntawm cov roj teeb lithium-ion.
Yog tias nws yog tiag tiag ze rau tus lej no, nrog qhov hnyav ntawm ntau pua kilograms Cov roj teeb rau lub tsheb fais fab yuav poob los ntawm ob peb lub kaum os (!) txog li 200 kilograms.... Qhov no tuaj yeem yog tus ntsia thawv hauv lub hleb ntawm cov tsheb hydrogen cell (FCEVs), vim tias Toyota Mirai hydrogen tanks ib leeg hnyav ze li ntawm 90 kg.
Qhov project yuav tsim nyob rau hauv kev txhawb nqa ntawm Oxis Zog (qhov chaw). Lub tuam txhab hais tias nws twb tau tswj los tsim cov hlwb nrog lub zog ceev ntawm 0,425 kWh / kg uas tuaj yeem siv rau hauv dav hlau. Txawm li cas los xij, lawv lub neej ntev thiab kev tiv thaiv rau lub voj voog tawm tsis paub.

Qhov no yuav txaus siab rau koj:
