Allotrope Energy develops Ionic Supercapacitors
Supercapacitors find use in applications with a large number of charge/discharge cycles. They store one or two orders of magnitude more energy per unit volume as compared to electrolytic capacitors. Ionic supercapacitors store energy through the interaction of a charged electron and an oppositely charged ion. These provide both the high energy density of a battery and the high power density of supercapacitors.
British startup Allotrope Energy develops ionic supercapacitors. The startup’s supercapacitors combine high surface area carbon with advanced electrolytes. It provides both high energy and high power electric double-layer capacitors (EDLC). These supercapacitors are applied in automotive components, hybrids, and rapid charging applications.
Capacitech builds a Cable-Based Capacitor (CBC)
Cable-based capacitors are physically flexible, making them easy to wrap around wires or circuit boards. This enables space-saving advantages when compared to traditional supercapacitor technologies. Additionally, CBCs provide peak-power assistance, reduce power fluctuations and electromagnetic interference, as well as retain charge from intermittent sources in power harvesting applications.
US-based startup Capacitech offers cable-based capacitors to the CleanTech industry. The startup’s supercapacitors feature two concentric electrodes with energy storage materials alongside a separator and an electrolyte between them. Capacitech’s products find applications in electronics, solar power, and energy storage.
EnergoPlus Tech produces a Hybrid Capacitor
Hybrid capacitors provide the safety and reliability of electrolytic capacitors with the advantages of supercapacitors. Moreover, they have higher operating voltage, as well as higher power density, compared to other types of supercapacitors. By eliminating the need for additional energy storage devices, they reduce costs in a range of applications such as power generation, energy recovery, and electric transportation.
EnergoPlus Tech is a Latvian startup developing hybrid supercapacitors. The startup’s capacitors use materials based on carbon nanotubes (CNTs) and polyaniline. Their supercapacitors are stable during long-term cycling and have a capacity of 600 F/g. The startup’s products are suitable for use in batteries for smart devices, electric cars, and other energy storage applications.
FlexCap Energy works on a Flexible Supercapacitor
Wearables and other lightweight, portable electronics necessitate the development of flexible supercapacitors. Flexible supercapacitors use flexible electrodes to combine structural flexibility with the high power density of supercapacitors. Startups are experimenting with hybrid electrodes and metal oxide nanomaterials to develop energy-efficient flexible supercapacitors.
Canadian startup FlexCap Energy provides lightweight and flexible energy storage solutions. The startup offers customized thin-film supercapacitors for smartwatches, wearable devices, and flexible electronics. Their flexible supercapacitor products provide high overall performance when stretched or bent.
SECH manufactures Capacitor Cells
Supercapacitors outperform both batteries and capacitors, enabling new applications in the energy and automotive industries. Capacitor cells stack supercapacitors to provide a higher density alternative for batteries. These are energy-efficient solutions that also allow quick charging/discharging. Capacitor cells find applications in automotive, transportation, and energy among others.
