NASA’s Perseverance Rover recently made a successful landing on Mars, embarking on a two-year mission to seek signs of ancient life and collect samples. Because Mars is extremely cold—nighttime temperatures can drop below -112 F—heaters are required to keep the rover’s battery system from freezing. Now, researchers reporting in ACS’ Nano Letters have 3D printed porous carbon aerogels for electrodes in ultralow-temperature supercapacitors, reducing heating needs for future space and polar missions.

Coaxial fiber-shaped supercapacitors with short charge carrier diffusion paths are highly desirable as high-performance energy storage devices for wearable electronics. However, the traditional approaches based on the multistep fabrication processes for constructing the fiber-shaped energy device still encounter persistent restrictions in fabrication procedure, scalability, and mechanical durability.

Titanium Carbide Graphene Hybrid Supercapacitor Match NiMh Battery Energy Density. Batteries store large amounts of energy but are slower to discharge energy. Supercapacitors can only store about one-tenth of the energy of a battery but are quicker at discharging it. They are used as a secondary power supply in devices such as smartphones, cameras and laptops, and have a far longer cycle life.
