Batutuwar Aluminum Air: Me Ya Shiga Wani?
Baterai yana da ya fi kadan. Wannan matsalai na iya ba da baterai suka zama masu shirin gini da aka amfani da su a wurare da kuma abubuwa da inda ana bukatar wani abu mai kadan.
An baterai aluminum air ta yi nasarar wannan batu. Ta amfani da hawa a cikin cathode, wanda ya haifar da rayuwarsa.
A cikin baterai aluminum air, an amfani da aluminum a cikin anode, kuma hawa (oxygen a cikin hawa) a cikin cathode. Hakan ya haifar da energy density - ya'ni energy da ake bayar da shi daga wata unit weight of the battery - da ma'ana mai kadan da zuwa baterai masu sadarwa.
Amma har da haka baterai aluminum air ba a yi aiki a cikin tattalin arziki, domin cost mai yawa na production ta anode, kuma abubuwa game da corrosion ta aluminum anode saboda carbon dioxide a cikin hawa. Saboda haka, amfani da wannan baterai ya kasance da muhimmanci a cikin abubuwan military.
Energy density mai kadan na baterai aluminum air suna nuna cewa akwai kyakkyawan mutum waɗanda suke amfani da su a cikin vehicles masu electric.
Yadda ake yi baterai aluminum air ce ta ƙarami - kuma za a iya yi da abubuwa masu gida. Za a rubuta DIY (Do It Yourself) guide don in yi baterai aluminum air.
Tattaunawa Baterai Aluminum Air
Don in yi wannan tattaunawa, muna bukata,
Foil aluminum.
Kadon ruwa da salt
Bloating papers
Dust charcoal mai kadan.
Biye small pieces of electric wires and
One light emitting diode.
Bayanin Yadda ake Yi Baterai Aluminum Air Mai Kalmomi
Ka saka piece of aluminum foil kafin ka fada shi a cikin table. A pot make a saturated solution of water and salt. Ka saka piece of bloating paper. Get the piece of bloating paper soaked by saturated salt solution.
Then get the soaked piece of bloating paper spread over the aluminum foil. Now put some fine dust of charcoal over the bloating paper. After keeping a non-insulated wire lead in the charcoal dust, cover it with another piece of salt solution soaked bloating paper of same size. Now tightly roll the total thing in such a way that, no charcoal dust can touch directly the aluminum foil and insulated portion of the lead wire comes out from one end of the roll. Now take another wire and fix the non insulated portion of the wire to the aluminum foil. Now if we connect a low rated light emitting diode (LED) with these two leads (one from charcoal and other from aluminum foil) and press the roll with our fingers, the LED will glow.
Siffarun Yadda Baterai Aluminum Air Ya Fara
Kamar a cikin figure right, baterai aluminum air tana da cathode mai hawa wanda ya kamata a yi silver based catalyst kuma tana taimaka wajen ci gaba CO2 zuwa baterai amma tana ba O2 zuwa electrolyte. Daga baya oxygen tana ci gaban H2O a cikin KOH electrolyte solution takes electrons from solution and creates OH– ions. These ions then associate with Al anode and create Al(OH)3 and release electrons. These electrons then flow to the air anode from aluminum cathode through the external circuit for compensating lack of electrons in the electrolyte solution due to cathode reduction reaction.
Chemical Reaction of Aluminum Air Battery
Four aluminum atoms react with 3 oxygen molecules and 6 water molecules and produce 4 aluminium hydroxides
Equation of Aluminum Air Battery
The anode oxidation (half-reaction),
The cathode reduction (half-reaction),

Phinergy, a well known Israeli developer company focused on utilization of metal air battery like aluminum air battery and zinc air battery. The specialty of air metal battery is that they take oxygen from ambient air. Aluminum air battery has very high energy density, it is as high as 300 Wh per one ib of aluminum. Its power density is also very high, around 30 Watt/lb.
Wannan ɗaukan baterai ba zan iya a kunna a cikin electrically. Bisa ga haka, shine primary battery. Amma abin da ake iya karɓe wannan ɗaukar kunna ne a cikin mechanical recharging process. Mechanical recharging of aluminum air cell is done by replacing aluminum electrode. In this process, the battery can be turned to its fully charged condition from discharged battery cell stack.
Because of its high energy and power densities, facilities of mechanical recharging, aluminum air battery is may be the most suitable alternative of petroleum fuel for automobile in near future. These battery also have very low environmental impact.
The main disadvantage of this technology is, the reaction of CO2 with aluminum. Aluminum gets very easily affected by corrosion due to the presence of CO2 in the air. This problem can be overcame by introducing special air electrode which can prevent CO2 to reach to the aluminum sheet. Phynergy has developed an air electrode with silver based catalyst and this structure lets O2 enter into aluminum sheet and prevents CO2 to enter.
