Maxwell Technologies Inc. (San Diego, CA) has introduced its new K2 series large cell BOOSTCAP ultracapacitors. About the size of a soda can, the K2 series BOOSTCAP cells operate at 2.7 volts and incorporate design and construction enhancements for high performance, durability, and a long operating lifetime.

Primary applications for the K2 series products - which range from 650 to 3,000 farads - include automotive subsystems, hybrid and electric vehicle drive trains, renewable energy systems, back-up power, grid stabilization, electric rail system power, and many other transportation and industrial applications that require burst power and heavy cycling that cannot be efficiently provided by a battery or power supply alone.

The K2 cell design features a rugged welded electrical pathway with increased contact and higher surface area.
