New Class of 2D Materials Stores Electrical Energy

MXenes are 2D materials forming multi-layered particles (left) from which pseudocapacitors are made. Shining X-ray light on MXenes revealed changes of their chemical structure upon intercalation of urea molecules (right) compared to pristine MXenes (center).

There are different solutions for storing electrical energy: Lithium-based electrochemical batteries, for example, store large amounts of energy, but require long charging times. Supercapacitors, on the other hand, are able to absorb or release electrical energy extremely quickly - but store much less electrical en
