Batteries and electrochemical capacitors

solar and wind power, offers enormous potential for meeting future energy demands. But access to solar and wind energy is intermittent, whereas electricity must be reliably available for 24 hours a day: Even second-to-second fluctuations can cause major disruptions that cost tens of billions of dollars annually. Electrical energy storage devices will therefore be critical for effectively leveli...

Batteries and Electrochemical Capacitors

The invention of the battery can be attributed to Alessandro Volta (1745-1827) of Como, Italy, who in 1800 described an assembly consisting of plates of two different metals, such as Zn and Cu, placed alternately in a stack-like fashion separated by paper soaked in an aqueous solution, such as brine or vinegar. As discovered by Volta, this contraption was capable of producing an electrical shoc...

Materials for electrochemical capacitors.

Electrochemical capacitors, also called supercapacitors, store energy using either ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudo-capacitors). They can complement or replace batteries in electrical energy storage and harvesting applications, when high power delivery or uptake is needed. A notable improvement in performance has been achieved thro...
