This task builds on previous EDNA tasks involving batteries: Network Zero Devices and Energy Harvesting Technologies.  Today’s   Li-ion batteries have a series of severe limitations, such as slow charging, limited life and safety issues. In addition, their technology is based on the use of rare materials which can lead to environmental and social issues.
The objective of this task is to examine new battery technologies suited to powering small devices such as IoT, actuators and sensors, and portable devices such as mobile phones and laptops. For example, a new energy storage solution based on carbon nanotube (CNTs) super capacitor might be an emerging technology, which is promising, but at a rather early stage.
