Lithium Ion Batteries

PMBL can manufacture Lithium Ion batteries from cells by Varta, GP, Saft, Sanyo and many others

Advantages and Limitations of Lithium Ion Batteries

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.
