This time we will spend our day investigating the technology that allows us to bring our smartphones everywhere — batteries. The program includes a lecture by Associate Professor Stanislav Fedotov on the present and future of metal-ion batteries, a master class during which you will learn to make a solar cell using titanium oxide and berries, an exhibition of energy technologies, as well as a no-lose lottery, in which you can win a visit to the Energy Center or memorable souvenirs.
