Our Ultracaps
FastCAP Systems uses nanotechnology to improve an energy storage device called an ultracapacitor (ultracap). Our ultracaps are the durable workhorses of the energy storage field, with extremely long life spans and unmatched durability. They recharge in just seconds and can deliver very strong bursts of power — far beyond the power capabilities of traditional batteries and ultracaps on the market today. Importantly, FastCAP's ultracapacitors contain no lithium and carry zero risk of thermal runaway explosions — a stark contrast to volatile lithium-based battery chemistries that are prevalent today. FastCAP's high-performance ultracapacitors stand to make a huge impact in industries and applications where harsh environments are the norm, and safety, reliability and ultra-high performance are essential.
