Maselo a Zinc okhala ndi zotupa zazing'ono. Kuchulukirachulukira kwamphamvu komanso kuchuluka kwa ntchito zozungulira
Mabatire a lithiamu-ion ndiye muyezo komanso chizindikiro chosungira mphamvu. Koma ofufuza nthawi zonse amayang'ana zinthu zomwe zimapereka ntchito yofananira pamtengo wotsika kwambiri wopanga. Chimodzi mwazinthu zomwe zikulonjeza ndi zinc (Zn).
Mabatire a Zn-x ndi otsika mtengo kwambiri. Amangoyenera kulipidwa
Ma depositi a Zinc amwazikana padziko lonse lapansi, titha kuwapezanso ku Poland - monga gulu lomwe tidawadyera masuku pamutu kuyambira 2020 (!) Zaka zana mpaka kumapeto kwa zaka 12,9. Zinc ndi chitsulo chotsika mtengo komanso chosavuta kupeza kuposa lifiyamu chifukwa chimakhala chothandiza m'makampani, kupanga padziko lonse lapansi kuli mamiliyoni (2019 miliyoni mu 82) osati matani masauzande (2020 zikwi XNUMX) monga amaganizira. malo mu kalata. Kuphatikiza apo, zinc yakhala maziko a maselo kuyambira zaka za zana la XNUMX ndipo imagwiritsidwabe ntchito m'maselo otaya (mwachitsanzo, maselo amchere otengera zinc oxide ndi manganese).
Chovuta ndikupeza ma cell a zinc kuti ayendetse maulendo osachepera mazana angapo ndikusunga mphamvu zomwe zakonzedwa.... Njira yopangira batire ndi anode ya zinki imayambitsa kusakhazikika kwa maatomu achitsulo pa elekitirodi, yomwe timadziwa ngati kukula kwa dendrite. Ma dendrites amakula mpaka atathyola zolekanitsa, kufika pa electrode yachiwiri, amachititsa kuti thupi likhale lalifupi, ndikupangitsa selo kufa.
Mu Meyi 2021, pepala lasayansi lidasindikizidwa momwe mawonekedwe a cell okhala ndi electrolyte yodzaza ndi mchere wa fluorine adafotokozedwa. Mcherewo umagwira ntchito ndi zinc pamwamba pa anode kupanga zinc fluoride. Chigawo cholumikizira chinali chotheka ku ma ion, koma chinatsekereza ma dendrites.... Komabe, chinthu chotetezedwa motere sichinafune kubwezera ndalamazo (zinali ndi kukana kwakukulu kwamkati, gwero).
Njira yotheka kuonjezera reactivity yake ikufotokozedwa mu pepala lina la kafukufuku woperekedwa ku zinki cell cathodes zochokera mkuwa, phosphorous ndi sulfure. Zotsatira zake? Ngakhale ma cell a zinc amapatsa mphamvu kachulukidwe mpaka 0,075 kWh / kg, maselo aposachedwa a zinki okhala ndi ma cathode atsopano. mphamvu 0,46 kWh / kg... Mosiyana ndi ma cell am'mbuyomu a Zn-air, omwe nthawi zambiri amatha kutaya, amayenera kukhalitsa zikwi zozungulira zogwirira ntchito, ndiko kuti, koyenera kugwiritsidwa ntchito m'mafakitale (gwero).
Ngati zonse zomwe zapezedwa zitha kuphatikizidwa, kutsimikiziridwa ndikuchulukitsa kupanga, ma cell a zinki atha kukhala maziko osungira mphamvu zotsika mtengo m'tsogolomu.
Kutsegula chithunzi: reusable zinc batire ("batire zamchere"). Kutengera kuya kwa kutulutsa, imatha kupirira maulendo angapo mpaka mazana angapo (c) Lukas A CZE
Chidziwitso kuchokera kwa akonzi a www.elektrowoz.pl: M'mabuku achingerezi, zinc air cell amatchedwa mafuta cell chifukwa amatenga mpweya kuchokera mumlengalenga. Kuchokera kumalingaliro athu, zilibe kanthu ngati njirayo ndi yosinthika, mwachitsanzo, ma cell amatha kulipiritsa ndikutulutsidwa nthawi zambiri.
