make an aa battery
Bookmarked 569 weeks ago
in this video well show how to make an aa batterywarning: potassium hydroxide is corrosive zinc is a heavy metal and manganese dioxide is an irritant wear gloves when handling themget a 5 ml plastic syringe the one i got was from a company called bd and the catalogue number was 309603 discard the plunger and cut off the tip also cut the back up to the 5 ml markget a 5 by 3 cm sheet of zinc metal about 05 mm thick cut into the 3 cm side a series of cuts about half a centimetre long roll the sheet so it fits into the syringe tube dont roll it too tight so it falls out it should be big enough that it stays in by frictiononce you have the right diameter pull it out and bend inward the tabs we cut earlierthis should now form a zinc canprepare the cathode powder by mixing 8 grams of manganese dioxide and 3 grams of carbon powder this will provide enough cathode powder to make about ten batteriesthe carbon is just a conductor for the oxidant which is the manganese dioxide the best manganese dioxide to use has the gamma type crystalline structure the more common beta type crystalline structure will still work but will give lower current so try and get the gamma type if you can if you make your manganese dioxide electrochemically then it will be of the gamma form while manganese dioxide made pyrolytically is usually of the beta formnow get some filter paper or a coffee filter and cut a rectangle about 5 by 10 centimetres to that pour a five centimetre line of about one gram of the cathode powder also insert a 7 centimetre length of 2 mm thick pencil lead into powder roll that into the paper and fold over one side so it doesn039t spill outnow get the zinc can we made earlier and insert the cathode roll into it cut off or tear any excess paper if there is too much cathode powder that it doesn039t fit then youll need to pour some off if there is too little then youll need to take it out and add morenow insert the assembly pencil end first into the syringe container from earlier make sure the pencil lead goes through the hole in the tip then break off the exposed pencil lead and leave 2 mm for electrical contactfill the battery with electrolyte by dropping the whole thing in solution of 30 g of potassium hydroxide in 50 ml of water leave it for several minutes to soak in and then take it out and leave it on some tissue for another several minutes to drain out any excessand thats your battery mine had an open circuit voltage of about 1412 volts and two of them could power a cheap digital clocknow i know some of you are wondering what the electrochemistry is behind the alkaline battery under load the zinc anode reacts with the potassium hydroxide electrolyte to give zinc oxide and two electrons these electrons then go through the load and at cathode they travel through the carbon to the manganese dioxide the manganese dioxide reacts with water to produce manganese iii oxide and hydroxide ions the reactions stops and the batteries dies when either the zinc or the manganese dioxide is consumed or when the waste products build up and block further chemistry
