CAP-XX launches 0.6mm Thinline supercapacitors to power wearable, ultra-portable and connected IoT devices
Eliminated materials and changed processes to reduce thickness and costs to below $1
Sydney, Australia – May 18, 2015 – CAP-XX (LSE:CPX), developer of flat supercapacitors for burst and back-up power in space-constrained electronic devices, today launched its Thinline series of single-cell supercapacitors. The world’s thinnest at 0.6mm thick, and with prices starting at less than US$1 in large volumes, Thinline was developed to address the size, weight and cost challenges of designing thin, sometimes disposable electronic devices for the Internet of Things (IoT). Examples include wearables (medical, fitness and health monitors, smart watches, drug delivery systems), portables (active credit cards, smartphones, RFID tags), and connected electronics (smart homes and smart buildings, electronic shelf labels, wireless sensor networks).
To reduce thickness and manufacturing costs, CAP-XX increased the power and energy density in its electrode materials to deliver equivalent performance in about half the volume, and eliminated the folded edges and copper terminals that contribute to thickness in its standard line supercapacitors. (For comparison, CAP-XX’s thinnest traditional single-cell supercapacitor is 1.10mm.)
CAP-XX supercapacitors benefit from a unique nanotechnology construction that stores electrical charge in engineered carbon electrodes on aluminium foil, to minimize resistance and maximize capacitance (scroll down to “CAP-XX Nanotechnology” in the CAP-XX Photo Gallery to view diagrams). This unique electrode construction packs the highest energy and power densities possible into thin, prismatic packages.
Supercapacitors can handle peak power events, supporting batteries and energy harvesters configured to provide low-power current at maximum efficiency. This architecture allows designers to use smaller, cheaper, low-power batteries and extend their run-time and cycle life, or use intermittent ambient energy sources such as solar photovoltaic. Supercapacitors also enable ultra-quick device charging and wireless power transfer, and provide the backup needed for graceful shutdown and “last gasp” transmissions in mission-critical applications.
CAP-XX Thinline supercapacitors support power requirements in IoT devices including wireless communication (Bluetooth, Bluetooth Smart, Zigbee, Z-Wave, Ant, active RFID), electronic paper and OLED displays, haptic or tactile feedback, vibration alerts, GPS acquisition, and injection or inhalation systems for drug delivery.
The idea was born while working with a customer designing a disposable insulin pump. “We figured out how to eliminate materials and change some processes to reduce costs and thickness,” explained Anthony Kongats, CAP-XX CEO.
Thinline works with thin-film, solid-state, and other low-power batteries such as coin cells/button cells, energy harvesting modules (solar, vibration/kinetic, RF, and other ambient energy sources), as well as inductive/wireless and cable/cradle fast-charging systems.
Key features of CAP-XX Thinline include:

Extremely thin, flexible packaging from 0.6mm (600µm) thick
Best-in-class power density and power output (up to 117kW / litre)
Ultra-low resistance, even at low temperatures (ESR from 16mΩ, 2x nominal at -40°C)
Excellent energy storage to support ambient/intermittent sources (up to 0.8Wh / litre)
High cell voltages to facilitate integration with primary batteries (up to 2.75V continuous)
Wide operating temperature range (from -40°C to +85°C)
Very low leakage current to maximize battery life and minimize losses (typically < 1µA)
Virtually unlimited charge-discharge cycle life

CAP-XX Thinline supercapacitors are available in three footprints:

“A” series: 19.5mm x 20.0mm x 0.6 – 0.9mm thick, 60 – 180 mF, 45 – 200 mΩ
“W” series: 28.0mm x 20.2mm x 0.6 – 0.9mm thick, 100 – 300 mF, 24 – 120 mΩ
“S” series: 39.0mm x 20.2mm x 0.6 – 0.9mm thick, 180 – 540 mF, 16 – 75 mΩ

Suggested retail price for all 0.6mm cells is less than US$1 in large volumes. The 0.7mm and 0.9mm cells in each series have higher C/lower ESR and cost slightly more.
All parts are available in a 2.3V / 70°C, or 2.75V / 85°C configuration. They can be assembled by soldering or welding (ultrasonic, laser or spot).

CAP-XX, a world leader in supercapacitors, is pleased to announce that following delivery of the first test and evaluation samples of its automotive supercapacitor units under its MoU with a Global Tier-1 auto components company, test results under the program to date have been very encouraging.
Based on these tests, the customer has placed orders for additional units, which CAP-XX will manufacture at its Lane Cove facility in Australia for delivery to the customer in Q3 2015.
The company is also encouraged by initial industry feedback on its recently launched range of Thinline supercapacitors.
Commenting on the automotive MoU, CAP-XX Chief Executive, Anthony Kongats, said “We are delighted to have received a follow-on order for automotive supercapacitors under our Tier-1 MoU and are very encouraged by initial feedback from our customer.”

CAP-XX ships Thinline Supercapacitors

CAP-XX, a world leader in supercapacitors, is pleased to announce that it is very encouraged by initial industry feedback for its recently launched range of Thinline supercapacitors, following shipment of sample units for evaluation to manufacturers of wearable devices, energy harvesters and smart credit cards.
19 distributors and end customers have placed initial orders for evaluation samples of these supercapacitors, which are optimised to address the demands of new applications in the fastest growing market segments of the internet of things (IoT).
As a result of customer feedback received in the 7 weeks since the Thinline launch, the Company is considering granting exclusivity for specific market applications.
Commenting on the launch, CAP-XX Chief Executive, Anthony Kongats, said
“CAP-XX is very encouraged by the industry response to the evaluation of our recently launched range of Thinline supercapacitors, which directly addresses the demands of developers of devices for the IoT.”
