Magnesium siv lithium-ion roj teeb? Cov European Union txhawb nqa E-MAGIC qhov project.
Cov European Union tau txhawb nqa E-MAGIC qhov project hauv qhov nyiaj ntawm 6,7 lab euros (sib npaug rau 28,8 lab PLN). Nws lub hom phiaj yog los tsim cov roj teeb magnesium (Mg) anode uas tsis yog tsuas yog denser tab sis kuj muaj kev nyab xeeb dua li tam sim no siv lithium-ion roj teeb.
Hauv cov roj teeb lithium-ion, ib qho ntawm cov electrodes yog ua los ntawm lithium + cobalt + nickel thiab lwm yam hlau xws li manganese lossis aluminium. Txoj haujlwm E-MAGIC tab tom tshawb nrhiav qhov muaj peev xwm hloov tau lithium nrog magnesium. Nyob rau hauv kev tshawb xav, qhov no yuav tsum tso cai rau koj los mus tsim hlwb nrog ntau dua lub zog ceev, pheej yig dua thiab saum toj no tag nrho, kev ruaj ntseg tshaj lithium-ion hlwb, vim hais tias lithium yog ib co reactive caij, uas yog ib qho yooj yim mus pom los ntawm cov menyuam cov video hauv qab no.
Raws li tus lwm thawj ntawm Helmholtz Institute Ulm (HIU) tau hais tias, "magnesium yog ib qho ntawm cov neeg sib tw tseem ceeb rau lub sijhawm sau ntawv." Magnesium muaj ntau valence electrons, uas tso cai rau nws khaws ntau zog (nyeem: roj teeb yuav loj dua). Kev kwv yees thawj zaug yog 0,4 kWh / kg nrog tus nqi ntawm tes tsawg dua € 100 / kWh.
> European project LISA tab tom pib. Lub hom phiaj tseem ceeb: tsim cov lithium-sulfur hlwb nrog qhov ceev ntawm 0,6 kWh / kg.
Nyob rau tib lub sijhawm, qhov teeb meem ntawm dendrite kev loj hlob hauv magnesium electrodes tseem tsis tau pom, uas nyob rau hauv lithium-ion hlwb tuaj yeem ua rau degeneration thiab tuag ntawm lub cev.
E-MAGIC project aims los tsim magnesium anode cell uas ruaj khov thiab ruaj khov. tuaj yeem them ntau zaus... Yog tias qhov no ua tiav, cov kauj ruam tom ntej yuav yog los tsim tag nrho cov txheej txheem tsim khoom rau cov roj teeb magnesium. Hauv lub moj khaum ntawm E-MAGIC, tshwj xeeb, lawv koom tes nrog ib leeg. Helmholtz Institute, Ulm University, Bar-Ilan University thiab Cambridge University. Qhov project yog teem kom tiav hauv 2022 (qhov chaw).
