Carbon nanotube structures as innovative electrode materials for more efficient energy storage devices

Final Report Summary - NANOTUBE ENERGY (Carbon nanotube structures as innovative electrode materials for more efficient energy storage devices)

The goal of this project was to develop carbon nanotube-based electrodes for batteries and supercapacitors to increase their energy/power. In our proposal, we intended to use different kinds of carbon nanotubes in order to considerably improve the performance of:
1. Li ion batteries for electric vehicle applications.
2. Super (electrical double layer, EDL) capacitors as very high power density devices.
3. Lead Acid battery technology, in order to make it suitable for load leveling applications (i.e. providing many thousands of discharge-charge cycles at 100% depth of discharge).

In short, CNTs proved very valuable for supercapacitors and for lead acid batteries while they were found non-essential for Li-ion batteries. Over a dozen publications have been published since the start of the project on the above research areas and in the synthesis of nanostructures led by Dr. Nessim.

The reintegration of Dr. Nessim was smooth and, as a full faculty member in the chemistry department at Bar Ilan University, he was able to build his lab and to publish multiple papers in high impact factor journals. This research helped him also to strengthen his collaboration with Professor Doron Aurbach with whom he co-published important papers.
Additionally, Dr. Nessim has presented his research in many prestigious conference venues in Israel and USA.
The team of the Nessim lab is now fully operational and the lab is equipped with state-of-the-art thermal and plasma-enhanced chemical vapor deposition (CVD) systems.
Overall, we believe that this project was totally successful and achieved its goals.
