Abstract: Deposition of the manganese dioxide (MnO2) Thin Film (TF) was carried out by Electron beam (E-beam) evaporation technique. Structural, optical, and electrical characteristics reveal that ...

Germany has connected the world’s first supercapacitor-based STATCOM to the grid, with Siemens Energy and transmission system operator TenneT positioning it as a blueprint to replace fossil-fuel ...

Abstract: Supercapacitors start to become major energy storage for electrical and electronic applications other than batteries. It provides better charging and discharging cycle in terms of time and ...

Supercapacitors are a special type of electrochemical energy storage device noted for their ability to deliver sudden bursts of energy. Batteries typically provide the bulk energy required for ...

Single-use water bottles could soon charge your devices instead of polluting landfills. Researchers have developed new methods to upcycle poly(ethylene terephthalate ...

Lots of single-use water bottles made from poly(ethylene terephthalate) (PET) end up in landfills, but there’s a growing interest in upcycling them instead ...

Scientists have been working for the last few years on enhancing concrete – arguably the most common construction material on the planet – to store energy. That includes researchers at Massachusetts ...

To store energy, batteries use chemistry, or rather, chemical potential. They consist of two electrical terminals (an anode and a cathode) separated by an electrolyte. When coupled to an external ...
