The battery industry is enormous, with worldwide revenues of approximately $45 billion. It is highly fragmented with at least 20 major manufacturers in each technology segment. Because of the wide range of applications of batteries, companies have tended to specialize in a particular technology or market application. Disposable batteries, such as the widely available carbon-zinc and alkaline cells, are available in standard sizes such as AA, C, and D, and they are a fast-moving consumer-good category with emphasis on manufacturing efficiency and scale, marketing and branding, and distribution efficiency.
One of the earliest forms of rechargeable battery was the wet

The cells contain a lithium-salt electrolyte carried in an organic solvent.
The lithium polymer battery is a variation on the Li-ion design. Rather than use an electrolyte, these batteries employ a solid polymer composite such as polyacrylonitrile. This has the advantage of a lower manufacturing cost and is more robust against physical damage. These batteries also use a flexible, foil laminate case, so they can be fabricated in a wider variety of shapes. Lithium polymer batteries started appearing in consumer electronics around 1996, and their popularity increased when

designers started to exploit the capability of making them in form-fitting shapes, as in Apple’s iPod and iPhone.
Li-ion and lithium polymer rechargeable batteries have many advantages over NiMH. They do not have any ―memory effect‖ which causes them to hold less charge depending on what kind of charging cycle was used, but they do degrade over time.
Lithium batteries also have some not-so-well-known disadvantages. Typically they lose some percentage of their capacity every year, and they only can be recharged approximately 400 times.
Newer technology is on the horizon to enable the number of charging cycles to be increased by threefold, but this will require continuous R&D investment. They also have some well-known safety issues such as a rash of fires and other safety concerns.
