Kwayoyin Zinc tare da ƙananan fashewa. Babban ƙarfin kuzari da dubunnan zagayowar aiki
Batirin lithium-ion shine cikakken ma'auni da ma'auni a fagen ajiyar makamashi. Amma masu bincike koyaushe suna neman abubuwan da ke samar da aƙalla irin wannan aiki a ƙananan farashin masana'anta. Ɗaya daga cikin abubuwan da aka yi alkawari shine zinc (Zn).
Batirin Zn-x suna da arha sosai. Sai dai a biya su
Tushen Zinc yana warwatse a duk faɗin duniya, Hakanan zamu iya samun su a Poland - a matsayin al'umma mun yi amfani da su daga karni na 2020 (!) har zuwa ƙarshen shekaru 12,9. Zinc karfe ne mai arha kuma mai sauƙin samu fiye da lithium kamar yadda yake da amfani a masana'antu, samar da duniya yana cikin miliyoyin (2019 miliyan a cikin 82) kuma ba a cikin dubun dubunnan ton (2020 dubu a cikin XNUMX) kamar yadda aka ɗauka. wuri a cikin wasika. Bugu da ƙari, zinc ya kasance tushen sel tun ƙarni na XNUMX kuma har yanzu ana amfani dashi a cikin ƙwayoyin da za a iya zubarwa (alal misali, ƙwayoyin alkaline dangane da zinc oxide da manganese).
Kalubalen shine a sami ƙwayoyin zinc suyi gudu aƙalla ƴan ɗaruruwan zagayowar yayin da suke kiyaye ƙarfin da aka tsara.... Hanyar yin cajin baturi tare da zinc anode yana haifar da rashin daidaituwa na atom na ƙarfe akan lantarki, wanda muka sani da girma dendrite. Dendrites suna girma har sai sun shiga cikin masu rarrabawa, sun isa lantarki ta biyu, suna haifar da gajeren kewayawa, kuma suna haifar da tantanin halitta ya mutu.
A cikin Mayu 2021, an buga wata takarda ta kimiyya wacce a cikinta aka kwatanta halayen tantanin halitta tare da electrolyte da aka wadatar da gishirin fluorine. Gishiri sun amsa da zinc akan saman anode don samar da zinc fluoride. Layer junction ya kasance mai yuwuwa zuwa ions, amma ya toshe dendrites.... Duk da haka, ɓangaren da aka karewa ta wannan hanya ba ya so ya dawo da cajin (yana da tsayin daka na ciki, tushen).
An bayyana wata hanya mai yuwuwar haɓaka aikinta a cikin wata takarda bincike da aka keɓe ga cathodes cell na zinc dangane da jan karfe, phosphorus da sulfur. Tasiri?
