ʻO ka Magnesium ma kahi o nā pākahi lithium-ion? Kākoʻo ka European Union i ka papahana E-MAGIC.
Ua kākoʻo ka European Union i ka papahana E-MAGIC i ka nui o 6,7 miliona euros (e like me 28,8 miliona PLN). ʻO kāna pahuhopu ʻo ia ka hoʻomohala ʻana i nā pihi anode magnesium (Mg) ʻaʻole i ʻoi aku ka ʻoi aku o ka ʻoi aku ka ʻoi aku ka palekana ma mua o nā pā lithium-ion i hoʻohana ʻia i kēia manawa.
I loko o nā pākahi lithium-ion, hana ʻia kekahi o nā electrodes i ka lithium + cobalt + nickel a me nā metala ʻē aʻe e like me ka manganese a i ʻole alumini. Ke ʻimi nei ka papahana E-MAGIC i ka hiki ke hoʻololi i ka lithium me ka magnesium. Ma ke kumumanaʻo, pono kēia e ʻae iā ʻoe e hana i nā cell me ka nui o ka ikehu kiʻekiʻe, ʻoi aku ka liʻiliʻi a ma luna o nā mea āpau, ʻoi aku ka palekana ma mua o nā cell lithium-ion, no ka mea, ʻo ka lithium kahi mea hoʻoheheʻe nui, maʻalahi ke ʻike ma ka nānā ʻana i ke wikiō ma lalo.
E like me ka hope pelekikena o ka Helmholtz Institute Ulm (HIU) i ʻōlelo ai, "ʻo ka magnesium kekahi o nā moho koʻikoʻi no ka wā ma hope o ka kākau ʻana." ʻOi aku ka nui o nā electrons valence o ka Magnesium, kahi e hiki ai iā ia ke mālama i ka ikehu hou aku (heluhelu: hiki ke ʻoi aku ka nui o nā pākahi). ʻO nā koho mua he 0,4 kWh/kg, me ke kumu kūʻai kelepona ma lalo o €100/kWh.
> E hoʻomaka ana ka papahana Europa LISA. ʻO ka pahuhopu nui: e hoʻokumu i nā cell lithium-sulfur me ka density o 0,6 kWh / kg.
I ka manawa like, ʻaʻole i ʻike ʻia ka pilikia o ka ulu ʻana o ka dendrite i nā electrodes magnesium, i loko o nā cell lithium-ion hiki ke alakaʻi i ka degeneration a me ka make o ka ʻōnaehana.
Ke manaʻo nei ka papahana E-MAGIC e hana i kahi cell anode magnesium i paʻa a paʻa. hiki ke hoʻopaʻa ʻia i nā manawa he nui... Inā kūleʻa kēia, ʻo ka hana aʻe e hoʻolālā i ke kaʻina hana holoʻokoʻa no nā pā magnesium. Ma ke ʻano o ka E-MAGIC, ʻo ia hoʻi, hui pū lākou me kekahi. Helmholtz Institute, University of Ulm, Bar-Ilan University and University of Cambridge. Hoʻopau ʻia ka papahana ma 2022 (kumu).
Ma ke kiʻi: ke kiʻikuhi o ka pākēneka manekene (Mg-anthraquinone) (c) National Institute of Chemistry
