For green, maintenance-free energy storage and power-delivery solutions

The global outcry among consumers, governmental agencies and forward-thinking corporations for cleaner, more energy-efficient products is at an all-time high. Manufacturers are under more pressure than ever to develop systems and solutions that use less and conserve more – and to do so while remaining competitive. These events have kept energy-use optimization at the forefront of system design and retrofitting, turning challenges into market opportunities for progressive companies and engineers – many of whom now rely on Maxwell’s industry-leading energy-optimization solutions.

UlTRAcApAcITORS: pROven, enAblInG TecHnOlOGy Even with recent advances, traditional power sources, like batteries, still present certain design and performance limitations. When integrated with enabling, power-dense ultracapacitors, however, designers and retrofit engineers suddenly gain access to a wider range of energy storage, management and delivery options.

MAxwell, THe MARkeT leAdeR Maxwell Technologies and its full line of industry-leading ultracapacitor cells and multi-cell modules have been the preferred solution in more than a million products, in applications ranging from consumer and industrial electronics to renewable energy and hybrid vehicle design.

Maxwell’s reputation as a technology innovator began in 1965, as a government research contractor specializing in advanced physics, pulsed power and space-effects analysis.

After shifting its focus to commercial applications in the 1990s, Maxwell grew to become a leading developer and manufacturer of innovative energy-storage and power-delivery solutions based on a broad range of ultracapacitor cells and modules. Maxwell ultracapacitors have been installed around the world and can deliver 12 GW of peak power.

Today, Maxwell solutions set the standard for reliability and value. We also lead the market in volume, having shipped millions of units through our global channel-partner network. Through our worldwide service organization, Maxwell continually assists and educates users and partners through value-added services that include design and application support, training and consulting.

THe ROle And USe OF UlTRAcApAcITORS Ultracapacitors offer millions of times more capacitance than conventional electrolytic capacitors. They are dependable, power-dense energy-storage devices that charge and discharge in as little as fractions of a second.

Ultracapacitors are ideal for applications requiring a quick pulse of energy that cannot be efficiently provided by a battery or power supply. A versatile and economical design option, ultracapacitors store energy and deliver power bursts safely and reliably for one million or more cycles.

Because of their unique design and performance advantages, you’ll find ultracapacitors in use throughout the world, in industries spanning electronics to vehicle manufacturing. Maxwell ultracapacitors typically last longer than the systems into which they are integrated.

MAxwell’S pATenTed FAbRIcATIOn pROceSS The secret to Maxwell components’ low cost and unparalleled longevity and performance lies in a proprietary electrode fabrication process. Porous, high-purity activated carbon is rolled and formed into super-capacitive double-layer electrodes, which are suspended in a special electrolyte and either layered into a prismatic (square) or wound into a cylindrical “jelly roll” configuration. The result is an extremely durable, maintenance-free product offering excellent power density and exceptional design versatility. Proof of Maxwell’s innovation and leadership includes more than 220 patents and patents pending.

“A combination of ultracapacitors and batteries can improve gas mileage in all vehicles.”dR. STeven cHU, U.S. eneRGy SecReTARy

Maxwell ultracapacitors enable engineers to design-in or retrofit systems with products that optimize energy efficiency, performance, reliability and cycle life. Ultracapacitors are a readily available power and energy option that’s used with great success in an ever-expanding number of applications.

wind Turbines: Wind is one of renewable energy’s fastest rising stars. Today, you’ll find Maxwell’s durable, maintenance-free ultracapacitors in tens of thousands of wind turbines worldwide, smoothing output and providing reliable fail-safe power for blade-pitch control and voltage regulation.

Solar power: Solar is another bright spot in renewable energy. But inconsistent panel quality, intermittent cloud cover and controller issues can make output power less than predictable. Maxwell ultracapacitors help overcome these issues. They also protect systems against surges and sags—absorbing energy when input suddenly spikes, and supporting output voltage when power drops out. Cost efficiency and long life (one million or more cycles) also make Maxwell ultracapacitors ideal for off-grid energy harvesting in remote signage and lighting applications.

Transportation: Every day, in nearly two thousand buses from China to Italy, dependable, low-maintenance Maxwell ultracapacitors are hard at work, enabling hybrid and all-electric drive technologies that save fuel and reduce emissions. In this use, ultracapacitors have proven to be the most efficient means of recapturing regenerative energy.

Automotive: Maxwell ultracapacitors’ unique energy-storage properties make them powerful “enablers” of emerging hybrid automotive applications and technologies, including boardnet stabilization, regenerative braking and distributed power. Car designers around the world have successfully integrated Maxwell ultracapacitors into the latest hybrid and EV (electric vehicle) models.

Industrial: Maxwell ultracapacitors are used extensively in the most demanding industrial environments and applications, primarily to provide burst power, backup power and peak-power shaving. Industrial product designers prefer ultracapacitors to other options for their inherent versatility and performance benefits, which include: low maintenance/high reliability; long life; and ability to operate normally in extreme temperatures. Common industrial uses include: Smart Grid automated meters; oil drilling; valve and actuator control; Enterprise Static State Disk (SSD) backup power; LED flashlights and remote lighting.

Heavy lifting: Designers seeking solutions for mining or material-handling have had to compromise either power or energy efficiency to achieve desired results. Many now specify cost-efficient Maxwell ultracapacitors because of their low maintenance and ability to quickly capture and discharge energy. Seaport cranes fitted with hybrid systems (battery plus ultracapacitors) have realized the greatest performance improvements, including greater power, better fuel economy, reduced emissions and quiet operations.

backup power: With lives, data and critical communications at stake, power loss is never an option. That’s why companies with datacenters, telecom and healthcare facilities rely on Maxwell ultracapacitors. Safe and virtually maintenance free, they provide the most reliable UPS source for temporary bridge and transition power.
