The increasing demand for renewable energy resources, such as solar and wind power, necessitates the development of large-scale electrical energy-storage (EES) systems, for example, for load leveling ...

In a major step toward next-generation electronics, researchers at the University of Minnesota Twin Cities have discovered a way to manipulate the direction of charge flow in ultrathin metallic films ...

A company called UniEnergy Technologies (UET) has installed a new large flow battery on the grid in Snohomish County in Washington state. The 2MW, 8MWh battery system may seem like a small ...

Flat, dye-like molecules with eight upright, pillar-shaped extensions self-assemble into pairs, interlocking like gears to form a tightly packed ring of 16 stacked layers. This structure allows charge ...

San Diego Gas & Electric (SDG&E) has taken the wraps off a new battery energy storage project that will store up to 2 megawatts of electricity — enough to power 1,000 homes for four hours. The new ...

An electric current is a flow of charged particles. A source of energy, such as a cell or battery, is required to make the free electrons move in one direction. Electrons are negatively charged ...
