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 ...

Like all capacitors, ultracapacitors have a high power density. Yet unlike their traditional counterparts, electrolytic capacitors, ultracapacitors offer high energy density, allowing them to store a ...
