Li-ion Battery

If you need a versatile, rechargeable battery unit, that is suitable for many consumer electronic products the Li-ion Battery may be what you are looking for. PMBL are specialists in designing and assembling Li-ion battery packs to deliver the power you need for your application or device.

Li-ion Battery Description

A Li-ion Battery (or to use it's full name of Lithium-ion battery) is a form of rechargeable battery in which the lithium ions move in one direction during discharge (from the anode to the cathode) and in the opposite direction (from the cathode to the anode) when charged. There is more than one type of Li-ion Battery, different types of li-ion batteries use alternative chemistry and have varied performance, cost, and safety characteristics.

Li-ion Battery cells use an intercalated lithium compound as the electrode material unlike primary lithium batteries which use electrode material of metallic lithium.

Li-ion Battery types are often found in consumer electronics. They are one of the most popular types of battery for portable electronic devices (laptops, mobile phones cameras) and have one of the best weight to energy, low energy leak rates when idle and no memory effect.
 
In addition to uses for consumer electronics, li-ion battery types are growing in popularity for defense, automotive, and aerospace applications due to their high energy density.  

Advantages

• High energy density, potential for yet higher capacities.
• Relatively low self-discharge, self-discharge is less than half that of Ni-Cd and NiMH.
• Low Maintenance, no periodic discharge is needed; no memory

.

Limitations

• Requires protection circuit, protection circuit limits voltage and current.
• Battery is safe if not provoked.
• Subject to aging, even if not in use, storing the battery in a cool place and at 40 percent state-of-charge reduces the aging effect.
• Moderate discharge current.
• Subject to transportation regulations, shipment of larger quantities of Li-ion batteries may be subject to regulatory control. This restriction does not apply to personal carry-on batteries.
• Expensive to manufacture, about 40 percent higher in cost than Ni-Cd. Better manufacturing techniques and replacement of rare metals with lower cost alternatives will likely reduce the price.
• Not fully mature, changes in metal and chemical combinations affect battery test results, especially with some quick test methods.
