Although Lithium cell technology has been used in low power applications for some time now, there is still not a lot of field data available about long term performance in high power applications. Reliability predictions based on accelerated life testing however shows that the cycle life matches or exceeds that of the most common technologies currently in use.

Lithium-ion batteries thus operate based on what is sometimes called the "rocking chair" or "swing" effect. This involves the transfer of Lithium ions back and forth between the two electrodes. The anode of a Lithium-ion battery is composed of Lithium, dissolved as ions, into a carbon or in some cases metallic Lithium. The cathode material is made up from Lithium liberating compounds, typically the three electro-active oxide materials, Lithium Cobalt-oxide LiCoO2 , Lithium Manganese-oxide LiMn2 O4 , and Lithium Nickel-oxide LiNiO2

Does not depend on SEI Layer for stability
No restriction on ion flow hence significantly higher charge and discharge rates possible as well as better low temperature performance.
Lower internal impedance of the cell
Higher temperatures can be tolerated.
No SEI build up over time means very long cycle life possible (10,000 deep cycles)
Public domain technology (No patent disputes)
