THE STORY OF BATTERIES

• by the Hungarian team

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- Plantés rechargeable battery
• 1868- Lelanches dry battery
• 1886- Carl Gassner and his invention
• 1889- Yai Sakizos development
• 1985- Lithium- ion battery from Japan

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 Batteries
• Nickel- Cadmium Batteries
• Lithium-ion batteries
• Silver-oxide batteries
• Lead-acid batteries

• Used in household gadgets, remote controls , etc.
• Inexpensive, rechargeable forms of alkaline
  batteries
• In cellular phones and consumer electronics
• In watches, they are the more common forms of
  button cell battery
• In automotive units, in cars, lawn-mowers, etc.

5
Recycling Options

• Heat is used to separate the high temperature
  metals (nickel, iron, steel) from the low
  temperature metals (zinc and cadmium)

6
Lithium ion batteries

• Heat is used carefully
• When exposed to heat, they have the potential to
  explode

7
Silver-oxide batteries

• They contain mercury, so they are hazardous
• They have an alpha-numeric code in which the
  first letters indicate what type of metals they
  contain
• L- manganese-dioxide
• S- siver-oxide
• Shredded to recover valuable
• metals

8
Lead-acid batteries

• 97 recycling rate
• Plastic new battery cases
• Lead cleaned, reprocessed
• Sulfuric 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.

5. Wait for good reception when youre using the
   Internet
6. Insulate your batteries
7. Clank up your batteries
8. Opt for plugging in
