Technology
Kyodo Printing will
develop a functional film that lengthens the life of a lithium-ion battery by
up to 20%. A resin that absorbs the gas is inserted between the films to
provide them with the function to adsorb the gas. The company will let the new
film adsorb volatile gas generated while a lithium-ion battery is used to
prevent the battery from expanding. The functional film will be used as the armoring
material pasted on the package of battery.
A lithium-ion
battery generates gas in the course of deterioration, and the package of a
battery expands. In the worst case, it bursts. That is why a mobile phone has
space inside in anticipation of the battery’s expansion. This space makes it
hard for mobile phone makers to make their products thinner. Kyodo Printing so
far developed functional materials including “MoistCatch” that adsorbs moisture
and “OxyCatch” that adsorbs oxygen. The technology used to develop these two
original products is used to develop the new film. The sample will be shipped
in less than one year.
