Misleading headline. Scientists have not really announced a battery. They just described a chemical process with some potential for a cheap organic battery if some hurdles can be overcome in some distant or unknown future.
When I hear cheap organic battery I think Lemon battery. Lemon trees grow OK in the silicon valley (Not as well as 400 miles further south.) So there should be a good source of lemons.
The problem with batteries and fuel cells is not the active chemicals, it is the case and insulators. Researcher need to find a good insulator which can pass electrons without catastrophic failure due to the reactions breaking the system down.
Designing a good battery that does not leak, would be an advantage too.
I was looking for a catch in this technology as this might be it: production scalability and market feasibility. Ofcourse i donot want to carry a chemical bomb in my pocket nor do i want to carry an extra bag just to carry my battery.
Every child should at some point construct a lemon battery. It was a fabulous learning experience for my kids, and a fun way for me to help them learn a little bit of basic circuit theory and electrochemistry.
