Our technology and products
BEYONDER develops a non-flammable, high power, cost-effective, sustainable, and durable battery technology, namely Li-ion capacitor (LiC), suitable for the Nordic low temperature environment. A LiC is a hybrid device that combines the capacitive cathode of a supercapacitor and the battery-type anode of Li-ion battery to inherit the advantageous specific power and specific energy of each technology. By using a wood-derived activated carbon cathode, the LiC can operate at higher specific power with greater durability compared to Li-ion batteries. By using a high capacity silicon anode, the LiC can achieve a high specific energy while remaining sustainably produced. Furthermore, because the electrolyte is an ionic liquid, the LiC is non-flammable, countering a major safety hazard of current technology, yet retaining high conductivity at low temperatures.
