Prismatic supercaps suit thin wearables
Designed to meet the demand for small, inexpensive, energy-efficient power solutions for thin wearables, the new 3V supercapacitors eliminate the cost and inefficiencies of the low-dropout (LDO) voltage regulator or buck converter often required to step the voltage down to work with the industry’s existing 2.7V-rated thin, prismatic 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 peak power (~100mA) needed for data collection and transmission. CAP-XX can handle those power bursts, and its new 3V supercapacitors can be placed directly across the battery without the intermediary LDO.
The company has successfully tested prototypes at 3V, 70°C meeting the IEC 62391 requirement for endurance. CAP-XX has started production trials, with samples expected for customers by end of August 2018, and mass production in the first half of 2019. The 3V versions, range from 0.9mm to 1.9mm in thickness, in 20x15mm, 20x18mm, 17.5×28.5mm, and 17.5×39.5mm footprints.
CAP-XX will then integrate the 3V technology into its larger prismatic supercapacitors, automotive modules and other products for high-energy, high-power applications.
