Experts from the University of Arizona have developed own version of an efficient power source for devices that are limited in size. A team of experts under the guidance of professors Chen Qian and Candice Chan offered to print the lithium-ion batteries on the base paper, and then add them as a stack.
The structural elements are printed on paper with ink containing carbon nanotubes, whereupon polyvinylidene covered surface. This approach will increase the capacity of the batteries up to 14 times, compared to monolithic power elements.
