SuperCapacitors

Safety Considerations for Acetonitrile SuperCapacitors Written By: Akihiro Kado Abstract: Advancements in SuperCapacitor design and manufacturing have made them a mainstay component in power supplies and backup systems that require high power density output. SuperCapacitors have now become commonplace components in many areas of modern electronic design. They bridge an important gap between batteries – used for high density energy storage, and electronic capacitors – for local power supply stabilization and decoupling. SuperCapacitors offer the unique ability to provide large amounts of power for short periods of time. For this reason, they have found a home in applications such as electric vehicles, uninterruptible power supplies, and data storage devices. A wide variety of SuperCapacitor structures and materials have been developed,

Advantages of SuperCapacitors for Power Constrained Backup Written By: Johnson Jiang Abstract: In most energy storage scenarios, the tradeoffs between power density and energy density quickly come to the foreground. This is best illustrated in the automotive industry, where power density directly translates to acceleration and driving performance, while energy density translates to the total range achievable on a tank of gas or, for an electric vehicle, on a single recharge cycle. This is true across almost every application, from wearable electronics to microgrid power networks on a college campus. This whitepaper from KYOCERA AVX will explore the advantages of SuperCapacitors, circuit level, uninterruptable power, and microgrid considerations, and the benefits that make them a more reliable option than traditional

SuperCapacitor Improvements on Small Generator Power Quality Written By: Ron Demcko | Ashley Stanziola | Daniel West Abstract: To expand portable electronics usage/reach/offering, the renewable power industry has taken an interest in the worldwide awareness of climate change and electronic waste, specifically how batteries affect the environment. One advancement is the emergence of modern low power hand crank generators, which roughly coincides with the accelerating interest in green energy used in portable electronics.

SuperCapacitors: A Reliable Backup Power Solution Written By: Johnson Jiang Abstract: Electric double-layer capacitors (EDLCs) are electrochemical capacitors called “SuperCapacitors,” or supercaps, due to their high energy density. Compared to traditional electrolytic capacitors, SuperCapacitors store electrical energy about two to three orders of magnitude higher and achieve several hundred thousand to millions of charge-discharge cycles. This advantage comes from the special construction of SuperCapacitors.

SuperCapacitors in Enterprise Servers and Smart Meters Written By: Jacky Cui | John Lee Abstract: The supercapacitor is one alternative to the traditional electrochemical battery for storing energy. In the age of lithium-ion (Li-ion) batteries, supercapacitors offer many attractive properties that no other device can deliver. At a high level, supercapacitors are composed of electrodes, an electrolyte, and an ion-permeable separator.

Using SuperCapacitors in Electric Vehicles Written By: Adrian Thomas Abstract: The improved performance and practicality of electric vehicles (EVs) have merited them a permanent foothold in the overall automotive market. When combined with geo-political and environmental initiatives, it is clear that the demand for EVs will continue to increase long into the future.

Charge Control Methods for SuperCapacitors: Methods to Protect Power Sources from Damage Due to High Current Demands of SuperCapacitors Written By: Ron Demcko | Joe Hock | Ashley Stanziola | Daniel West Abstract: Circuit designs exploiting the increased energy storage provided by supercapacitors, requires careful consideration of the increased power handling, than that of batteries, when charging these devices. The unique composition of electrochemical double-layer capacitors (EDLC) inherently allows them to withstand large currents. Table 1 below is a brief list of AVX cylindrical (SCC) and series-connected module (SCM) SuperCapacitors, displaying peak current supply and sink current capability. These maximum specifications will typically exceed current capability of charge sources, and lead to failures within the power supply system. Supercapacitors have
