Our company exclusively focuses on utilizing hybrid supercapacitor cells to develop customized battery solutions for our customers. Hybrid supercapacitors combine the advantageous properties of supercapacitor design with the energy capabilities of lithium-ion battery cells.
Since our initiation with hybrid supercapacitors approximately four years ago, significant advancements have been achieved. Initial cells had an energy density of 80 to 100 Wh/kg and a higher power rating of up to 20C. In the previous year, we introduced the new ultrasafe 4V 21700 cells, boasting an energy density of 130 Wh/kg and a power rating of 10C. Presently, we offer cells with approximately 150 Wh/kg, albeit with a slightly lower power rating. Our latest cell technology provides an impressive energy density of about 240 Wh/kg, surpassing that of most Li-ion battery cells.
Customer-specific hybrid supercapacitor cells
We specialize in creating hybrid supercapacitor cells tailored to each customer’s needs. These cells find diverse applications, such as single-cell use in IoT and portable devices, low-voltage power batteries for light electric vehicles (e.g. e-scooters, AGVs), and high voltage high-capacity/high-power batteries for various energy or power-driven applications (fuel cell generators, hybrid powertrains, energy on demand, UPS, etc.). While these applications have distinct voltage levels (ranging from 0 to 12V, 36 to 72V, 600 to over 800V), each battery’s capacity, power ratings, and dimensions tend to differ. To ensure compatibility, Altreonic often designs custom enclosures for the batteries to seamlessly integrate them into the respective systems. This approach also extends to the cells used within the battery, particularly when space and energy/power requirements are stringent for a given application.
Altreonic now offers this capability in collaboration with its cell manufacturing partners.
Following cells have already been developed:
The 8256G 4V 5.25 Ah small pouch cell (82x56x9 mm), featuring 191 Wh/kg
The 18650 4V 3.3 Ah cylindrical cell with and without protection circuit, featuring 245 Wh/kg
A small 40x20x7mm 4V pouch cell with 0,47 Ah / 1,47 Wh (155 Wh/kg).
Above are “energy-type” cells, and ideal for IoT type applications. The cells can operate from -20 to +60°C (with some limitations) and deliver over 10000 cycles.
