At Technology Review’s EmTech conference last week, MIT professor Joel Schindall told the audience at a panel on energy storage why ultracapacitors may have a significant role to play in our ...

How Does an Ultracapacitor Work? Like a battery, a single ultracapacitor cell consists of a positive and negative electrode separated by an electrolyte. However, they store energy electrostatically, ...

Scientists have designed an ultracapacitor that maintains a near steady voltage. The novel constant-voltage design may one day help ultracapacitors find new uses in low-voltage electric vehicle ...

Tesla is integrating Maxwell’s ultracapacitor business months after the acquisition, several employees confirmed, but it’s unclear if it’s only to comply with existing contracts or if they plan to ...

Effenco, a Canada-based specialist in electric propulsion systems for heavy-duty vocational vehicles, announced an ultracapacitor-based energy storage system for 100% electric trucks. The company was ...

In the frenzy over energy storage technologies, ultracapacitors sometimes ends up looking like wallflowers because they traditionally haven't been able to storage as much power as certain battery ...

It is is a dream come true for energy seekers: a portable energy source that outperforms the best lithium-ion batteries on the market and produces 10 times the power of lead-acid batteries at half the ...

Many system applications require that capacitors be connected together, in series and/or parallel combinations, to form a "bank" with a specific voltage and capacitance rating. The most critical ...

Standard capacitors store energy in an electric field created when opposite electrical charges collect on two plates separated by a thin insulating material. In ultracapacitors the surface area of the ...

Chemical batteries power many different mobile electronic devices, but repeated charging and discharging cycles can wear them out. An alternative energy storage device called an ultracapacitor can be ...
