Inside the "disappearing battery" revolution — how forest-powered supercapacitors could keep wireless…
- Forest-powered supercapacitors could replace batteries in IoT devices and sensors
- Swedish startup uses forest-derived lignin polymer to replace toxic metals
- S-Power offers quick charging, a long 8-10 year lifespan, and other savings
Swedish startup Ligna Energy hopes its new S-Power technology could solve the unsustainable demand for batteries as demand for indoor environmental sensors, wearables and other IoT endpoints surges.
The company argues that a growing number of these devices don’t actually require built-in energy storage due to the fact that they consume minimal energy and can operate intermittently. Those that can harvest environmental energy, like light, RF signals, vibration and temperature differences, could be among the most suited to this futuristic tech.
Ligna’s flagship S-Power 2S offers 1.2F capacitance, a 2.7V operating voltage, 0.5Ω Equivalent Series Resistance and more than 250,000 charge cycles, but more importantly, this ultra-thin pouch-format cell is designed to be suitable for even the smallest...
