Nowadays, lithium-ion batteries (LIBs) are not only powering various mobile IT devices (laptop PCs, cellular phones, mp3 players etc.) but expected to play critical roles in transportation (HEV, EV), robots, and electricity storage for renewable energy. LIBs outperform traditional competitors (NiMH, NiCd, Lead-acid) in terms of energy density, power density, and operation life. However, safety aspect is a major concern that should be settled before LIBs’ spreading into the upcoming application fields which require challenging standards both in performance and reliabilities. Passivity that has been widely employed in the field of corrosion, is the concept of the kinetic barrier sustaining unstable or unfavorable thermodynamic state of a certain system. Passivity is intimately involved in our present metal and semiconductor -based environment. This talk will address the operation and safety mechanisms of LIBs in respect of passivity will be addressed. How deeply LIBs are relying on the passivity, and how passivity is supposed to extend the limits of LIBs in the future will also be addressed. This presentation is intended as an introductive program especially for the prospective electrochemists who are interested in the LIBs.
