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 ...

(PhysOrg.com) -- A new ultracapacitor or electric double-layer capacitor (DLC) design has been announced in the journal Science this week, and could pave the way for smaller and lighter portable ...

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 ...

San Francisco company Aura Aerospace is working on a remarkably odd idea: replacing batteries in electric VTOL air taxis with high-powered "Powercell" ultracapacitors capable of massive power output ...

As reported by Bloomberg, Tesla has acquired the innovative energy storage company Maxwell Technologies for $218 Million. The move is a direct departure from Tesla’s current energy storage ...

Municipal transit agencies have tried to reduce the carbon footprint of their bus fleets using a range of options over the years, from biofuels and hydrogen to batteries and hybrid-electric diesel.

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, ...

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 ...
