TL;DR · WeSearch summary

A Swedish startup, Ligna Energy, is developing forest-derived supercapacitors to replace traditional batteries in IoT devices. Their S-Power technology offers quick charging and a lifespan of 8-10 years, making it suitable for various applications. This innovation aims to reduce the unsustainable demand for batteries as the need for wireless sensors grows.

Key facts

▪Ligna Energy's S-Power technology uses forest-derived lignin polymer to create supercapacitors.
▪These supercapacitors can charge quickly and last for over 250,000 charge cycles.
▪The technology is designed for small devices that require minimal energy, making it ideal for IoT sensors.
