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
Solutions
• Virus-powered batteries• Self-charging batteries• CVD crystal
