Energy storage systems come in many forms, leveraging different technology types. A class of electrochemical storage, lithium-ion batteries have established themselves as the industry standard.

But there are many new technologies vying for their market share.

Sodium-ion batteries are widely considered a sustainable and resource-saving answer to future energy storage, while flow batteries offer a viable alternative in long-duration storage applications.
However, the path to commercialization is not a straightforward one.

Fraunhofer IEE develops simulation tools for hybrid storage systems design The researchers have created a degradation model that experts can use to determine battery aging in hybrid systems made up of lithium-ion batteries and supercapacitors. This makes it possible to determine whether it makes sense to combine the two technologies in individual cases. The tools should also help with the design of a hybrid system.
