Maxwell’s industry-leading ultracapacitors are breakthrough energy storage and delivery devices that offer millions of times more capacitance than traditional capacitors.  They deliver rapid, reliable bursts of power for hundreds of thousands of duty cycles – even in demanding conditions.

A New Standard

Ultracapacitors create a new standard of energy-use optimization.  They are ideal for applications ranging from wind turbines and mass transit, to hybrid cars, consumer electronics and industrial equipment.  Available in a wide range of sizes, capacitance and modular configurations, ultracapacitors can cost-effectively supplement and extend battery life, or in some cases, replace batteries altogether.

Lowering Costs, Increasing Value

Proprietary advances in material science, coupled with process optimization and global manufacturing enable Maxwell to keep costs down and quality high.  This agility enables our product teams to tailor device design and performance to a wide spectrum of industry-specific uses.
