The move was in response to other international airlines implementing the same procedure to assure its passengers of the added safety onboard the aircraft. “Safety is the cornerstone of our operations. You've probably noticed that they also differ in composition: There are those that are built with Lithium-Ion (Li-Ion) and those with Lithium Polymer (Li-Poly). We take a look at the difference between these two rechargeable batteries and how they affect construction of devices. Lithium-Ion (Li-Ion) Then came Lithium-Ion, a type of battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Development for Li-Ions started as early as 1912 but were only popularized in the 90s when Sony and Asahi Kasei first released them commercially.
