Handheld devices (clocks, watches, cameras, MP3 players ...) are powered by batteries. Each battery is designed for a particular purpose.
Battery saline
It is the oldest and least expensive batteries, but also less efficient.
The reagents consumed and releasing energy during operation, are manganese dioxides and zinc metal. This cell also contains ammonium chloride described as "salt", hence the name given to this type of battery.
This battery supplies a voltage of 1.5 V. It is used for less demanding applications (alarm clocks, toys ...), because its lifetime is relatively short.
The alkaline battery
This battery, almost the same constitution as a battery saline contains more potassium hydroxide. Potassium is a metal of the family of alkaline, hence the name given to this type of battery.
This battery also delivers a voltage of 1.5 V. It can provide higher currents as the battery and salt for longer. So should she uses most demanding digital cameras, MP3 players ...
Alkaline battery is on average twice as expensive than salt pile.
The lithium battery
This lithium battery, at equal volume, far more power than its predecessors, but it is even more expensive. The reagents are lithium metal (replacing zinc) and various metal oxides. According to the oxide used, the terminal voltage is different (from 1.2 V to 3.5 V).
It is used in flat calculator for other uses long-term low intensity such as watches, tools heart ...
Cells facing recycling
Every year in France, almost 29 000 tons of batteries, or nearly one billion units, are used. If we add the batteries, there are thousands of tons of heavy metals such as zinc, manganese, cadmium, nickel, lead and mercury that should prevent the release into the environment as they are dangerous to health.
Accumulate in living organisms, animals or plants, they can cause poisoning and serious diseases, it is necessary to prevent contamination of soil and groundwater. For this, one answer: the recovery and recycling.
Since 1999, it is forbidden to dispose of li-ion battery with the rest of the garbage. However, too many people are unaware of and specific collection bins are not always easily accessible. The result is that inFrance
