CAP-XX launches thin 3V supercapacitors

“CAP-XX is initially targeting markets using 3V coin cell batteries, where popular batteries such as the CR2032 have reasonable energy, ~220mAh, but have trouble delivering the ~100mA needed for data collection and transmission,” said the firm.

The capacitors will range from 0.9 to 1.9mm thick and come in the same footprints as the firm’s existing 2.7V thin prismatic supercapacitors: 20 x 15mm, 20 x 18mm, 17.5 x 28.5mm and 17.5 x 39.5mm.

Initial samples, expected by the end of August, will be in the larger package. Other footprints will follow, as will 0.6mm ‘Thinline’ products.

Leakage current is expected to be approximately 1.5µA for a 500mF cell at 3V, reducing to ~ 0.7µA at 2.5V.

Prototypes have been tested at 3V 70°C and meet the IEC 62391 endurance requirement.

To achieve the 3V operation, the firm developed new materials and production techniques.

Mass production scheduled for the first half of 2019, and larger 3V prismatic supercapacitors and 3V automotive modules are planned.

CAP-XX CEO Anthony Kongats covered the 3V supercaps in the paper ‘Using thin prismatic supercapacitors to support 3V coin cell batteries’, which he presented today at IDTechEx in Berlin.
