Magnesium maimakon batirin lithium-ion? Ƙungiyar Tarayyar Turai tana tallafawa aikin E-MAGIC.
Tarayyar Turai ta goyi bayan aikin E-MAGIC a cikin adadin Yuro miliyan 6,7 (daidai da miliyan 28,8 PLN). Manufarsa ita ce haɓaka batura anode na magnesium (Mg) waɗanda ba su da yawa amma kuma sun fi aminci fiye da batirin lithium-ion da ake amfani da su a halin yanzu.
A cikin batirin lithium-ion, daya daga cikin wayoyin ana yin su ne da lithium + cobalt + nickel da sauran karafa irin su manganese ko aluminum. Aikin E-MAGIC yana binciken yiwuwar maye gurbin lithium tare da magnesium. A cikin ka'idar, wannan ya kamata ya ba ka damar ƙirƙirar sel tare da mafi girman ƙarfin kuzari, mai rahusa kuma sama da duka, mafi aminci fiye da ƙwayoyin lithium-ion, saboda lithium abu ne mai saurin amsawa, wanda ke da sauƙin gani ta kallon bidiyon da ke ƙasa.
Kamar yadda mataimakin shugaban cibiyar Helmholtz Institute Ulm (HIU) ya ce, "magnesium yana daya daga cikin manyan 'yan takara na zamani bayan rubuce-rubuce." Magnesium yana da ƙarin valence electrons, wanda ke ba shi damar adana ƙarin makamashi (karanta: batura na iya zama girma). Ƙididdiga na farko shine 0,4 kWh/kg, tare da farashin tantanin halitta ƙasa da €100/kWh.
> Aikin Turai LISA yana gab da farawa. Babban burin: don ƙirƙirar ƙwayoyin lithium-sulfur tare da nauyin 0,6 kWh / kg.
A lokaci guda kuma, har yanzu ba a lura da matsalar ci gaban dendrite a cikin lantarki na magnesium ba, wanda a cikin ƙwayoyin lithium-ion na iya haifar da lalacewa da mutuwar tsarin.
Aikin E-MAGIC yana nufin ƙirƙirar tantanin halitta anode na magnesium wanda ke da ƙarfi da kwanciyar hankali. ana iya caje shi sau da yawa... Idan wannan ya yi nasara, mataki na gaba shine zayyana dukkan tsarin masana'antu don batir magnesium. A cikin tsarin E-MAGIC, musamman, suna aiki tare da juna.
