Zinc masero ane madiki madiki. High simba density uye zviuru basa cycles
Lithium-ion mabhatiri ndiwo akazara chiyero uye bhenji mukuchengetedza simba. Asi vaongorori vanogara vachitsvaga zvinhu zvinopa kanenge kamwechete kuita pamutengo wakaderera wekugadzira. Chimwe chezvinhu zvinovimbisa ndeye zinc (Zn).
Zn-x mabhatiri ari uye achave akachipa zvakanyanya. Vanofanira kungobhadharwa
Zinc deposits dzakapararira pasi rose, tinogonawo kuzviwana muPoland - senzanga takavashandisa kubva ku2020 (!) Makore kusvika pakupera kwemakore 12,9. Zinc isimbi yakachipa uye iri nyore kuwana kupfuura lithium sezvo inobatsira muindasitiri, kugadzirwa kwepasi rose kuri mumamiriyoni (2019 miriyoni mu82) pane makumi ezviuru zvematani (2020 zviuru muXNUMX) sezvaifungidzirwa. isa mutsamba. Pamusoro pezvo, zinc yanga iri hwaro hwemasero kubva muzana ramakore rechiXNUMX uye ichiri kushandiswa mumaseru anoraswa (semuenzaniso, alkaline masero akavakirwa pazinc oxide uye manganese).
Dambudziko nderekutora zinc masero kuti amhanye kweanenge mazana mashoma ma cycles uchichengetedza huwandu hwakarongwa.... Maitiro ekuchaja bhatiri ne zinc anode inokonzera kusagadzika kwemaatomu esimbi pa electrode, yatinoziva sekukura kwedendrite. Dendrites inokura kusvika yapaza nepakati pezviparadzanisa, inosvika kune yechipiri electrode, inokonzeresa pfupi, uye inoita kuti sero rife.
Muna Chivabvu 2021, bepa resainzi rakaburitswa umo hunhu hwesero ine electrolyte yakafumiswa nefluorine munyu yakatsanangurwa. Munyu wakaita zinc pane anode surface kuita zinc fluoride. Iyo junction layer yaigoneka kumaion, asi yakavharira madendrites.... Nekudaro, chinhu chakadzivirirwa nenzira iyi chaisanyatsoda kudzosera chaji (yaive neyakakura yemukati kuramba, sosi).
Nzira inogoneka yekuwedzera reactivity yayo inotsanangurwa mune rimwe basa rekutsvagisa rakazvipira kune zinc cell cathodes yakavakirwa pamhangura, phosphorus uye sarufa. Migumisiro? Nepo iyo zinc sero yakajairwa ichipa simba densities anosvika 0,075 kWh/kg, achangoburwa zinc-air masero ane macathodes matsva. vimbiso 0,46 kWh / kg... Kusiyana nekare Zn-air masero, ayo aiwanzoraswa, anofanirwa kugara zviuru zvematenderera ekushanda, ndiko kuti, yakakodzera kushandiswa kwemaindasitiri (mabviro).
Kana zvese zvakawanikwa zvichigona kusanganiswa, kusimbiswa uye kuwedzera kugadzirwa, zinc masero anogona kuve hwaro hwekuchipa kwekuchengetedza simba mune ramangwana.
Kuvhura mufananidzo: reusable zinc bhatiri ("alkaline bhatiri"). Zvichienderana nekudzika kwekubuda, inogona kumira kubva kune akati wandei kusvika kumazana akati wandei ekushanda ma cycles (c) Lukas A CZE
Cherekedza kubva kuvapepeti ve www.elektrowoz.pl: Muzvinyorwa zvemutauro weChirungu, mazinc air cell anodaidzwa kunzi fuel cell nekuti anotora oxygen kubva mumhepo. Kubva pamaonero edu, hazvina basa kana maitiro acho achidzokororwa, i.e. maseru anogona kubhadhariswa uye kuburitswa kakawanda.
