The secret to making the best energy storage materials is growing them with as much surface area as possible. Like baking,it requires just the fair mixture of ingredients prepared in a specific amount and order at just the fair temperature to produce a lean sheet of material with the perfect chemical consistency to be useful for storing energy. A team of researchers from Drexel University, Huazhong University of Science and Technology (HUST) and Tsinghua University recently discovered a way to improve the recipe and make the resulting materials bigger and better and soaking up energy—the secret? Just add salt.
