Oxygen-Ion Battery: A Solution for Large Energy Storage Systems

Lithium-ion batteries are ubiquitous today – from electric cars to smart-phones. But that does not mean that they are the best solution for all areas of application. TU Wien has now succeeded in developing an oxygen-ion battery that has some important advantages. Although it does not allow for quite as high energy densities as the Li-ion battery, its storage capacity does not decrease irrevocably over time: it can be regenerated and thus may enable an extremely long service life.
