subject: Lithium-polymer Battery With High Energy Density, More Compact [print this page] Rechargeable alkaline manganese batteries: alkaline manganese dioxide batteries is based on the developed, as applied to the mercury-free zinc powder and the new additive, it is also known as mercury-free alkaline manganese batteries. This does not change the original battery discharge characteristics of alkaline batteries at the same time, but also is charged with dozens to hundreds of times more affordable.
Lithium-polymer battery (Li-polymer, also called polymer lithium battery): with high energy density, more compact, ultra-thin, lightweight, and high security and low cost Duozhong obvious advantage, is a new battery. In shape, the lithium polymer battery technology with thin features, you can meet the needs of a variety of products, made into any shape and capacity of the battery. Such cells can reach the minimum thickness of up to 0.5mm.
Fuel cell: hydrogen and oxygen is a chemical reaction directly through the electrode into electrical energy. Specifically, the fuel cell is water electrolysis using the reverse reaction of "generator." Battery requires continuous supply of live material (from the reaction of the substance) - the fuel and oxidizer, which in turn, and quite different from other ordinary chemical batteries. The advantages of fuel cell energy conversion efficiency, high reliability, no noise when working, no dust, no radiation, is a clean source of energy. These small devices for cell phones, laptops, PDA and other portable devices to provide energy, and is currently used lithium ion batteries compared to the weight of only about half of the original lithium-ion battery fuel cell can provide about 4 times battery power. But this equipment is still in testing, it is estimated to be large-scale production in 2004 before entering the market. (The battery has not been applied to a player in, if applied, I believe the time can be Dedao Walkman tremendous increase) Laptop Battery
