I kēia mau lā, Zhang Ning, he mea hou electrode maikaʻi a me ka electrolyte, ua hoʻolālā i kahi mea maikaʻi hou a me ka electrolyte i loko o ka "wai-based zinc ion", a ʻo ka manawa mua i hoʻomaikaʻi maikaʻi a hoʻomaikaʻi ʻia ka hopena, palekana, kūpaʻa o ka zinc ion. "No ke aha i loaʻa ai kahi kaʻa uila i ka wā e pahū ai ke kelepona paʻa? "Ke kula o Ph.

D., School of Chemistry, Nankai University, i ʻōlelo hou aku nei, ua hoʻolālā ʻo ia i kahi mea maikaʻi hou a me ka electrolyte i loko o ka "wai-based zinc ion". No ka manawa mua, hoʻohana ʻia ka cationic defective zinc manganese oxide (ZnMn2O4) i ka electrode maikaʻi, ʻoiai ka hoʻohana mua ʻana he kiʻekiʻe Concentration nui anionic electrolyte trifluoromethane sulfonate (Zn (CF3SO3) 2), no laila ua hoʻomaikaʻi maikaʻi ʻia a hoʻomaikaʻi ʻia nā hopena ʻepekema pili i ka pono, palekana, kūpaʻa o ka zinc ion.

"American Chemical Society", aia ka hopena i kēia manawa. Wahi a Zhang Ning, ua hoʻohana nui ʻia ka pākaukau lithium-ion i ke ola o ka poʻe, akā no ka hoʻopili ʻana o ka lithium ions shuttle ma waena o nā pou maikaʻi a maikaʻi ʻole, ua maʻalahi ka hana ʻana i kahi metala nila, "kiʻi kiʻi lithium", no laila ke kumu o ka diaphragm i loko o ke kaapuni pōkole, a me ka hoʻohana ʻana i nā electrolyte flammable organic e hoʻemi nui i ka palekana o nā pā lithium ion. "Ma muli o ka waiwai a me ka liʻiliʻi o nā kumu waiwai zinc, ʻaʻohe mea hiki ke puhi a pahū ka wai electrolyte, a ua kūpono nā hiʻohiʻona no nā ʻōnaehana mālama ikehu nui, e like me nā grids akamai, no laila e aʻo mākou i ka pahuhopu i ka "wai-based zinc ion battery ".

"Ma ke ʻano o nā mea electrode maikaʻi, ua ʻike ʻo Zhang Ning a me kāna hui i ka mālama pono ʻana o Zn ma ka ʻimi mau ʻana i nā kūlana hoʻokolohua optimization, hoʻomaikaʻi nui i ka paʻa o ka puʻupuʻu zinc ion, a ʻoi aku ka kiʻekiʻe o ka hiki ke paʻa i ka 94%. A paʻa loa ka ʻōnaehana alkaline i kēia manawa, a ʻoi aku ka liʻiliʻi o ke ola pōʻaiapuni ma mua o 50 mau manawa, a wikiwiki loa ka hiki ke attenuation. ʻO kēia mea ka noi mua i loko o ka pākaukau zinc-ion aqueous.

"Water-based zinc ion" hiki ke hoʻomaikaʻi wale i ka hana pākaukau, palekana palekana, akā e hōʻemi hoʻi i nā kumukūʻai. Hoʻomaopopo ʻia ʻo ke kumukūʻai o ka zinc metala ma ka mākeke o kēia manawa e pili ana i 2 US kālā no ka kilokani, aʻo ke kumukūʻai lithium metala ma kahi o $ 300 no kg. He mea maʻalahi a maʻalahi nā kumu Zinc, a ʻoi aku ka maikaʻi no ka hoʻohana nui ʻana i ka hana hana.
