  • Today’s technology relies on insane amounts of electricity, and since we couldn’t stay hooked on walls all the time, we needed a portable solution. Batteries were the answer.
  • Nóri is going to speak about this, lots of data. In our increasingly mobile world, batteries serve quite a purpose. They power our cars, portable electronics and items we use every day. Batteries can even be made out of  vegetables . Batteries are identified by the product they're used for ("car battery," "cell phone battery," etc.) or its size ( "9V", "button cell"). But for scientific purposes, batteries' names are based on the metals they contain. Concerning disposal, the name can be helpful because it lets you know what elements are wrapped up in that cylindrical packaging Most batteries are based on some sort of chemical, such as Lithium, Zinc or sulfric acid, Alkaline Magnesium, Nickel, Cadmium , etc. To store chemical the chemical energy later to be converted into electrical energy. Since different batteries use different materials, different methods have to be used when disassembling them. A general first step is to remove the casing. Usually this is done gently, or for example in Lead Acid batteries, not so gently, with a huge industrial hammer. The chemicals are then separated using complex methods, different ones for every material. Not all, but luckily most types of batteries are 100% recycable. This not only makes manufacturing batteries cheaper, but also leads to more environment friendly energy consumption.
  • Panni…
  • First of all, David’s going to explain it for some time , then I’ll take over and get to CVD, which I will praise. It would be great to have these but they are far too expensive.

    • 1. THE STORY OF BATTERIESby the Hungarian team
    • 2. History of batteries• 1746- Pieter van Muschenbroek and the bottle of Leiden• 1791- Galvani published his works about animals’ electricity• Volta proved that metals have electricity• 1800- Voltaic pile• 1859- Planté’s rechargeable battery• 1868- Lelanche’s dry battery• 1886- Carl Gassner and his invention• 1889- Yai Sakizo’s development• 1985- Lithium- ion battery from Japan
    • 3. Types of batteries - identified by size• AAA-in mice• AA-TV controllers, lamps,• C-lamps• D-in lamps• 4,5 V• 9V
    • 4. Types of batteries identified by the use and content• Alkaline Manganese Used in household gadgets, Batteries remote controls , etc.• Nickel- Cadmium Inexpensive, rechargeable Batteries forms of alkaline• Lithium-ion batteries batteries In cellular phones and• Silver-oxide batteries consumer electronics In watches, they are the more common forms of button cell battery• Lead-acid batteries In automotive units, in cars, lawn-mowers, etc….
    • 5. Recycling OptionsHeat is used to separate the high temperature metals (nickel, iron, steel) from the low temperature metals (zinc and cadmium)
    • 6. Lithium – ion batteriesHeat is used carefullyWhen exposed to heat, they have the potential to explode
    • 7. Silver-oxide batteriesThey contain mercury, so they are hazardousThey have an alpha-numeric code in which the first letters indicate what type of metals they containL- manganese-dioxideS- siver-oxideShredded to recover valuablemetals
    • 8. Lead-acid batteries97% recycling ratePlastic new battery casesLead cleaned, reprocessedSulfuric acid neutralized, cleaned for human consumption
    • 9. What happens to the batteries collected in school?• In our school there is a box to collect batteries.• They carry all of the batteries to a hazardous waste dump to Germany (the name of the German company is unknown)• They dispose most of the batteries.
    • 10. 8 ways to optimize your battery use1. Replace only one at a time2. Use the ones with more hazardous ingredients!?3. Laptops aren’t for laps4. Keep your batteries cool5. Wait for good reception when you’re using the Internet6. Insulate your batteries7. Clank up your batteries8. Opt for plugging in
    • 11. Solutions• Virus-powered batteries• Self-charging batteries• CVD crystal
    • 12. Thank for your attention!
