A lithium-ion (Li-Ion) battery is a rechargeable battery with twice the energy capacity of a Nickel-Cadmium battery. It also offers greater stability and safety. Commonly used in consumer electronics such as cellular phones, digital photo/video cameras, and notebook computers.

Rechargeable battery that fully charges over a period of four hours, typically at 4.2 volts. Users do not need to fully discharge the battery before recharging.

See Li-Ion battery.

Type of accumulator which has a high gravimetric and volumetric energy density. The cell voltage (open circuit voltage) is governed by the electrode pairing and, for a Li2MnO2 / C combination for example, has a value of 3 V or 4 V, depending on the type of manganese dioxide used. This system is therefore recommended for applications such as mobile telephones, video cameras.

A battery in which lithium is used as an electrochemically active material and the electrolyte is a liquid which conducts lithium ions.

Battery that does not have memory effect and can be recharded at any time without loss of capacity.

Ultralife lithium-ion prismatic (rectangular) cells offer high energy density, high capacity and long cycle life in the most common, lightweight sizes. These cells, which operate over a wide temperature range, are ideal for portable devices such as cellular and mobile phones, PDA`s, notebook computers, MP3 players, military applications and any products requiring a reliable, high-energy power source. And like Ultralife`s Polymer rechargeable cells, our lithium-ion prismatic cells do not exhibit a memory problem, meaning that they can be recharged at any state of charge without first having to be completely discharged.

These batteries use lithium for the negative electrode and offer high energy density and the ability to undergo repeated charge cycles.

Lighter weight battery than earlier types, having relatively longer cycle life and generally do not suffer from memory effect.

Lithium ion batteries (sometimes abbreviated Li-Ion) are a type of rechargeable battery commonly used in consumer electronics. They are currently one of the most popular types of battery for portable electronics, with one of the best energy-to-weight ratios, no memory effect and a slow loss of charge when not in use. They can be dangerous if mistreated, however, and unless care is taken their lifespan may be reduced.
