Mvura-based zinc ion bhatiri rinopwanya mota yemagetsi nharembozha inoputika dambudziko

Munguva ichangopfuura, Zhang Ning, itsva yakanaka ye electrode zvinhu uye electrolyte, yakagadzira itsva yakanaka zvinhu uye electrolyte mu "mvura-based zinc ion" bhatiri, uye kekutanga mhedzisiro, kuchengeteka, kugadzikana kweiyo zinc ion bhatiri yakavandudza uye yakagadziridzwa. "Sei paine motokari yemagetsi inoitika pakaitika kuputika kwenharembozha? Nokuti mabhatiri e-lithium-ion avanoshandisa ane imwe njodzi yekuchengetedza. "Chikoro chePh.

D., Chikoro cheChemistry, Nankai University, akati munguva pfupi yapfuura, akagadzira chinhu chitsva chakanaka uye electrolyte mubhatiri ye "water-based zinc ion". Kekutanga, iyo cationic yakaremara zinc manganese oxide (ZnMn2O4) inoshandiswa mune yakanaka electrode, nepo yekutanga kushandiswa kwakakwira Concentration hombe anionic electrolyte trifluoromethane sulfonate (Zn (CF3SO3) 2), kuitira kuti kushanda, kuchengeteka, kugadzikana kwe zinc ion bhatiri yakawedzera zvakanyanya uye inovandudza mabheti ezvesayenzi, uye mhedzisiro yezvesayenzi inovandudzwa. Journals.

"American Chemical Society", mhedzisiro yave kuwanikwa. Sekureva kwaZhang Ning, bhatiri re lithium-ion rave richishandiswa zvakanyanya muhupenyu hwevanhu, asi nekuti iyo lithium ion shuttle inopindirana pakati pemapango akanaka uye akaipa, zviri nyore kugadzira simbi yetsono, "lithium graphics", saka Iyo diaphragm inokonzera mukati mapfupi kutenderera, pamwe nekushandiswa kweanopisa organic electrolyte kunoderedza zvakanyanya kuchengetedzeka kwebhatter lithium . "Sezvo zinc zviwanikwa zvakapfuma uye zvakachipa, mvura-based electrolyte haina njodzi dzinopisa uye dzinoputika, uye maitiro acho akakodzera mahombe emagetsi ekuchengetera masisitimu, senge magridi akangwara, saka isu tichadzidza chinangwa ku" mvura-based zinc ion bhatiri ".

"Panyaya yezvigadzirwa zvakanaka zvemagetsi emagetsi, Zhang Ning nechikwata chayo vakaona kuchengetedza kwakanaka kweZn nekuramba vachiongorora mamiriro ekuyedza ekugadzirisa, inosimudzira zvakanyanya kugadzikana kwebhatiri rezinc ion, uye chiyero chekuchengetedza simba chakakwira kusvika 94%. Uye iyo iripo alkaline system yakagadzikana kwazvo, uye hupenyu hwekutenderera kazhinji husingasviki ka50, uye kudzora simba kunokurumidza. Ichi chinyorwa ndicho chekutanga kushandisa mune aqueous zinc-ion bhatiri.

"Mvura-yakavakirwa zinc ion" bhatiri haingogone kuvandudza zvakanyanya mashandiro ebhatiri, kugadzikana kwakachengeteka, asi zvakare kuderedza mutengo. Zvinonzwisiswa kuti mutengo wesimbi zinc mumusika wazvino ungangoita 2 US madhora pakirogiramu, nepo simbi yelithium mutengo ingangoita madhora mazana matatu pakg. Zinc zviwanikwa zvakachipa uye zviri nyore, uye inonyanya kukodzera kushandiswa kwakakura mukugadzira maitiro.
