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 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.
10. 8 ways to optimize your battery use
1. Replace only one at a time
2. Use the ones with more hazardous ingredients!?
3. Laptops aren’t for laps
4. Keep your batteries cool
5. Wait for good reception when you’re using the
Internet
6. Insulate your batteries
7. Clank up your batteries
8. Opt for plugging in
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.

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.
