In this picture taken on Wednesday, March 9, 2016, Jan Prochazka, the president of Prague based He3Da company, presents his battery in Prague, Czech Republic. In the global race to create more efficient and long-lasting batteries, some are betting on nanotechnology - the use of minuscule parts - as the most likely to yield a breakthrough. Improving batteries’ performance is key to the development and success of many much-hyped technologies, from solar and wind energy to electric cars. Research into how to achieve that has followed several avenues, from using different materials than the existing lithium-ion batteries to changing the internal structure of batteries using nanoparticles - parts so small they are invisible to the naked eye.
