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...

Metamaterials: Snapping Mechanical Metamaterials under Tension (Adv. Mater. 39/2015).

By exploiting snap-through instabilities, D. Pasini and co-workers design a damage-tolerant mechanical metamaterial that snaps sequentially under tension, thereby accommodating a very large deformation up to 150%. On page 5931, they describe how the nonlinear mechanical response of the metamaterial can be robustly programmed by tuning the architecture of its unit cell.

Secondary Batteries: Lead Acid Battery Thermal Runaway Chapter Heading for Encyclopedia of Electrochemical Power Sources

The thermal runaway effect observed in sealed lead acid batteries is reviewed and reassessed as a means for understanding the effect at a more fundamental level. It is to be noted that a popular explanation for the heat generated when a sealed cell is overcharged is that the oxygen recombination taking place at the negative electrode is an exothermic process. Although it is a fact that this rec...
