Batirin iska zuwa iska yana ba da kewayon fiye da kilomita 1. Lalabi? Ana iya zubar da su.

Kwanaki kadan da suka gabata mun tabo kan "inginen injiniya," "mahaifin takwas," "tsohon sojan ruwa" wanda "ya ƙirƙira batura masu amfani da aluminum da kuma electrolyte mai ban mamaki." Mun sami ci gaban batun ba abin dogaro sosai ba - kuma godiya ga majiyar, Daily Mail - amma matsalar na bukatar fadadawa. Idan Birtaniyya suna mu'amala da batura-aluminium, to suna ... da gaske suna wanzu kuma suna iya ba da kewayon dubban kilomita.

Wanda ya kirkiro, wanda jaridar Daily Mail ta bayyana, “mahai ne mai ‘ya’ya takwas,” an gabatar da shi a matsayin wanda ya kirkiro wani sabon abu (ba mai guba ba) kuma tuni ya fara tattaunawa kan sayar da ra’ayinsa. A halin yanzu, an haɓaka batu na ƙwayoyin aluminium-iska na shekaru da yawa.

Amma bari mu fara daga farkon:

Abubuwan da ke ciki

• Aluminum-iska batura - rayuwa mai ƙarfi, mutu matasa
  • Model Tesla 3 Dogon Range tare da ajiyar wuta na 1+ km? Za a iya yi
  • Alcoa da Phinergy aluminum/batir na iska - har yanzu ana iya zubar da su, amma an tsara su sosai
  • Takaitacciyar ko me yasa muka soki Daily Mail

Aluminum-iska baturi amfani da dauki na aluminum tare da oxygen da ruwa kwayoyin. A cikin wani nau'i na sinadarai (za'a iya samun ma'auni akan Wikipedia), aluminum hydroxide yana samuwa, kuma a ƙarshe an haɗa haɗin ƙarfe tare da oxygen don samar da alumina. Wutar lantarki yana raguwa da sauri, kuma lokacin da duk karfen ya amsa, tantanin halitta ya daina aiki. Ba kamar batirin lithium-ion ba, Ba za a iya sake caji ko sake amfani da sel zuwa iska ba..

Ana iya zubar da su.

Ee, wannan matsala ce, amma sel suna da siffa ɗaya mai mahimmanci: gigantic yawa na makamashin da aka adana dangane da taro... Wannan ya kai 8 kWh / kg. A halin yanzu, matakin na yanzu mafi kyawun ƙwayoyin lithium-ion shine 0,3 kWh / kg.

Model Tesla 3 Dogon Range tare da ajiyar wuta na 1+ km? Za a iya yi

Bari mu dubi waɗannan lambobin: 0,3 kWh / kg don mafi kyawun ƙwayoyin lithium na zamani vs 8 kWh / kg don ƙwayoyin aluminum - Lithium kusan sau 27 ya fi muni! Ko da mun yi la'akari da cewa a cikin gwaje-gwajen, aluminum-air batura isa wani yawa na "kawai" 1,3 kWh / kg (source), wannan shi ne har yanzu fiye da sau hudu fiye da na lithium Kwayoyin!

Don haka ba kwa buƙatar zama babban kalkuleta don gano hakan Tare da batirin Al-air Tesla Model 3 Dogon Range zai kai kusan kilomita 1 akan baturi maimakon 730km na yanzu don lithium-ion.... Ba shi da ƙasa da Warsaw zuwa Roma, kuma ƙasa da Warsaw zuwa Paris, Geneva ko London!

Abin takaici, tare da ƙwayoyin lithium-ion, bayan tafiyar kilomita 500 tare da Tesla, mun haɗa shi zuwa caja don lokacin da mota ta ba da shawara kuma mu ci gaba. Lokacin amfani da ƙwayoyin Al-air, direban dole ne ya je tashar da ake buƙatar maye gurbin baturi. Ko guda daya module.
