Lithium- but it is hazardous.
lead-h2so4(sulphuric acid)
A common form of lead-acid battery is the modern wet-cell car battery. This can deliver about 10,000 watts of power for a short period, and has a peak current output that varies from 450 to 1100 amperes.
An improved type of lead-acid battery called a gel battery (or "gel cell") has become popular in automotive industry as a replacement for the lead-acid wet cell.
The gel battery contains a semi-solid electrolyte to prevent spillage, electrolyte evaporation, and out-gassing, as well as greatly improving its resistance to damage from vibration and heat.
Another type of battery, the Absorbed Glass Mat (AGM) suspends the electrolyte in a special fibreglass matting to achieve similar results.
More portable rechargeable batteries include several "dry cell" types, which are sealed units and are therefore useful in appliances like mobile phones and laptops.
Cells of this type (in order of increasing power density and cost) include nickel-cadmium (NiCd), nickel metal hydride (NiMH), and lithium-ion (Li-Ion) cells.

there are 4 types of battery in general use today.
first is ni-cad (nickel cadnium), this is rechargeable but has a memory. this means that it remembers the common charging cycle you put it through. if you always discharge the battery before recharge, the battery will last for 2000 full charges. if you recharge it partly full, the top up charge will become normal and if you empty it, it will only partially top up.
these were replaced by ni-mh (niclel hydride), these batteries are green in colour and need a special charger to regulate the current during charge. they are very common now and replace most standard cells.
the third type is mercury cells, these are the button cells in small devices but because of the poisoning effect of mercury, development of these cells has been stopped and a replacement is in development.
the fourth kind is li-ion (lithium ion), these are now in general use for mobile equiptment such as cameras and recorders. they hold a good charge without memory but it has been noted that they have a limited shelf life after initial charge. this means that the cell will only last a finite time before a replacement is needed.
depending how long ago it was first charged you may only get 1000 to 2000 charges from it.

Bepends on what kind of battery you are talking about. The are lead-acid,nickel-cadmium,lithium-ion,dry cell,wet cell and a variety of different batteries depending on application.

Lithium Ion is what it says on the battery for my cam corder?
