If you have ever tried to run a high-performance computer in a hot room, or pushed an electric vehicle to its limit on a scorching summer highway, you know the enemy of modern electronics is heat. As our devices get smaller and our power grids get hungrier, the components inside are being pushed to their thermal breaking points.

One specific component, the capacitor, has long been the weak link in this chain. Essential for regulating power flow in everything from medical defibrillators to electric vehicle (EV) inverters, capacitors provide quick bursts of energy that batteries simply can’t handle. But current polymer capacitors are fussy; they generally can’t survive temperatures above 212°F (100°C). This temperature ceiling forces engineers to add heavy, expensive cooling systems to keep them from melting or failing.

But a new study published this week in Nature finally offers a solution: a new material made from cheap, commercially available plastics that can handle four times the energy of a typical capacitor at temperatures up to 482°F (250°C).

Researchers developed a polymer capacitor by combining two cheap, commercially available plastics. The new polymer capacitor makes use of the transparent material — pictured here, with vintage Penn State athletic marks visible through it — to store four times the energy of typical capacitor and withstand significantly more heat.
