what is a battery?

• What is a battery cell?

  A single battery is also referred to as a Toshiba pa3399u-2bas laptop battery cell (e.g. 1 AA cell). Most battery packs contain rows of cells linked in series to increase the available voltage and the rows then linked parallel to increase the available capacity. A laptop battery pack typically contains 6 high power rechargeable Li-Ion cells.

• What is a Lithium-Ion Polymer Battery?

  Lithium-ion polymer battery lithium-ion batteries have similar characteristics, and the use of polymer electrolyte membrane. Dry polymer designed to allow this type of battery manufacture cheaper, smaller. The flexibility of the polymer electrolyte, and can shape to suit the needs of applications. Lithium-polymer batteries are often found in mobile phones and digital cameras.

• What is a Lithium Ion Battery (Li-Ion)?

  Lithium Ion batteries useLithium Oxide and a Carbon compound (usually Graphite) as the electrodes. The electrodes are separated by a microporous film which contains an organic solvent acting as the electrolyte. Compared to NiCd and NiMH batteries, Li-Ion batteries have a higher power to weight ratio, they are smaller and lighter yet provide the same power. Unlike NiCd and NiMH batteries, Li-Ion batteries do not suffer from the memory effect. Li-Ion cells also have much lower levels of self-discharging. These factors combined with the higher production costs mean that Li-Ion cells are comparatively more expensive. The Department of Chemistry at Oregon State University has an informative and technical page on battery chemistries and how these work.

• What is a Nickel Metal Hydride Battery (NiMH)?

  Using this battery type nickel and the other electrode and electrolyte is potassium hydroxide rare earth metal. Nickel-metal hydride batteries constructed from non-toxic metals to make them more environmentally friendly than other battery designs. Nickel-metal hydride batteries are similar because they are from the memory effect of nickel-cadmium batterys suffer, but they are lighter than the weight, with higher capacity, therefore, high power-weight ratio. Ni-MH battery than the nickel-cadmium batteries and greatly reduce the life of Li Li-ion batteries.

• What is a Nickel Cadmium / Ni-Cad Battery (NiCd)?

  This battery uses Nickel and Cadmium as its electrodes and aqueous Potassium Hydroxide as the electrolyte. It is an older type of battery, but is quick to charge and can handle higher loads. These batteries suffer from the "memory effect". Also due to the presence of heavy metals, they are environmentally unsafe and hazardous.
