As electronics demand higher energy density, one component has proved challenging to shrink: the capacitor. Making a smaller capacitor usually requires thinning the dielectric layer or electrode surface area, which has often resulted in a reduction of power. A new polymer material could help change that.
In a study published 18 February in Nature, a Pennsylvania State University-led team reported a capacitor crafted from a polymer blend that can operate at temperatures up to 250 °C while storing roughly…
