A Pinch of Salt Completes the Recipe for 2-D Materials in Supercapacitors

In joint research involving Drexel University in Philadelphia, and Huazhong University of Science and Technology (HUST) and Tsinghua University , both in China, scientists have found a way to formulate two-dimensional materials that are purer and have surface areas much closer to their theoretical maximum . The expected benefit: supercapacitors that store energy far better than ever. How did they do it? It turns out that they just needed to add a pinch of salt to coax the best out of them. In research described in the journal Nature Communications , the international team used the surface of salt crystals to serve as growth templates for transitional metal oxides. That new ingredient, say the researchers, makes the final product bake up bigger and better. "The challenge of producing a metal oxide that reaches theoretical performance values is that the methods for making it...
