Magnesium m'malo mwa mabatire a lithiamu-ion? European Union imathandizira pulojekiti ya E-MAGIC.
European Union inathandizira pulojekiti ya E-MAGIC mu ndalama za 6,7 miliyoni za euro (zofanana ndi 28,8 miliyoni PLN). Cholinga chake ndi kupanga mabatire a magnesium (Mg) anode omwe sali ochepa komanso otetezeka kuposa mabatire a lithiamu-ion omwe amagwiritsidwa ntchito pano.
Mu mabatire a lithiamu-ion, imodzi mwa ma elekitirodi amapangidwa ndi lithiamu + cobalt + nickel ndi zitsulo zina monga manganese kapena aluminium. Ntchito ya E-MAGIC ikuyang'ana kuthekera kosintha lithiamu ndi magnesium. Mwachidziwitso, izi ziyenera kukulolani kuti mupange maselo okhala ndi mphamvu zambiri, zotsika mtengo komanso pamwamba pa zonse, zotetezeka kuposa maselo a lithiamu-ion, chifukwa lithiamu ndi chinthu chogwira ntchito kwambiri, chomwe ndi chosavuta kuwona powonera kanema pansipa.
Monga wachiwiri kwa purezidenti wa Helmholtz Institute Ulm (HIU) adati, "magnesium ndi imodzi mwazofunikira kwambiri panthawi yolemba." Magnesium ili ndi ma electron ambiri a valence, omwe amalola kuti asunge mphamvu zambiri (werengani: mabatire akhoza kukhala aakulu). Kuyerekezera koyambirira ndi 0,4 kWh/kg, ndi mtengo wa cell wosakwana €100/kWh.
> Ntchito yaku Europe ya LISA yatsala pang'ono kuyamba. Cholinga chachikulu: kupanga maselo a lithiamu-sulfure okhala ndi 0,6 kWh / kg.
Panthawi imodzimodziyo, vuto la kukula kwa dendrite mu maelekitirodi a magnesium silinawonekere, lomwe mu maselo a lithiamu-ion lingayambitse kuwonongeka ndi imfa ya dongosolo.
Pulojekiti ya E-MAGIC ikufuna kupanga selo la magnesium anode lomwe liri lokhazikika komanso lokhazikika. ikhoza kulipitsidwa nthawi zambiri... Ngati izi zikuyenda bwino, chotsatira chidzakhala kupanga njira yonse yopangira mabatire a magnesium. Mu chimango cha E-MAGIC, makamaka, amagwirizana wina ndi mnzake. Helmholtz Institute, Ulm University, Bar-Ilan University ndi Cambridge University. Ntchitoyi ikuyembekezeka kumalizidwa mu 2022 (gwero).
