Electrochemical capacitors (ECs) have only recently been considered as an alternative power source for telemetry sensors of drilling equipment for geothermal or oil and gas exploration. The lifecycle analysis and modeling of ECs are underrepresented in literature in comparison to other storage devices e.g. Li-ion batteries.

Cornell Dubilier has announced that additional capacitance values and cell sizes have been added to its already extensive supercapacitor platforms, the DGH 2.7 volt and DSF 3.0-volt series. The expansion comes on the heels of the recent addition of cutting-edge LiC hybrid types which offer higher operating voltages and greater energy densities. Supercapacitors (aka EDLCs or ultracapacitors) are rapidly becoming essential components for power circuit designers. They are used to supplement rechargeable batteries or as replacements for batteries in a very diverse range of applications.

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.
