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- 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

Types of batteries - identified by size

• AAA-in mice • AA-TV controllers, lamps, • C-lamps• D-in lamps• 4,5 V• 9V

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….

Recycling Options

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

Lithium – ion batteries

Heat is used carefullyWhen exposed to heat, they have the potential

to explode

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-dioxideS- siver-oxideShredded to recover valuable metals

Lead-acid batteries

97% recycling ratePlastic new battery casesLead cleaned, reprocessedSulfuric acid neutralized, cleaned for human

consumption

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 theGerman company is unknown)

• They dispose most of the batteries.

8 ways to optimize your battery use

1. 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
