It has been noted that Lithium Ion Batteries (LIBs) are considered as one of the most successful innovations in the last thirty years. In fact, LIBs has reached to the maturity in technology, something which hasn’t happened for SIBs yet.
However, the main concern in this field is identified as the future limitation of lithium supply. As many anticipating, It would be a Lithium rush in 21 century.
Sodium looks the best alternative for Li in energy storage application with similar physical and chemical properties as Lithium and
the elemental abundance of Na in the earth’s crust is about three orders of magnitude larger than the Li abundance.
The Market of Flexible, Printed and Thin Film Batteries Will Reach ~$500 Million in 2030.
In design of a F-SIB, the key challenges would be:
•Developing advanced electro-active materials
•Design of innovative electrode structure : mechanical and chemical stability
•Harmony of flexibility properties, safety etc. for electrodes and electrolyte and even current collectors
•Sufficient packaging for outer layer, specially for stretchable batteries
•Integration of flexible SIBs with flexible solar cells or sensors
