History
The first battery was created in 1800 by Italian physicist and chemist Alessandro Volta. This battery was able to produce a stable electric current.
American physicist John Goodenough invented the first Li+ battery in 1980. This was revolutionary, as he discovered lithium to be light and to have the required electrochemical properties.
The Na+ battery was first developed by Aquion Energy in the United States in 2009. Very few companies have started mass producing these batteries.
Li+ batteries are now mass produced across the globe.
While the concept of batteries has been around, the use of fungi in batteries is very new- there have only been a few batteries created that actually incorporate fungi . . .
For example, a group of researchers 3D printed photosynthetic cyanobacteria onto a dead mushroom. These bacteria release electrons when they conduct photosynthesis, so when the researchers shined a light on them, they were able to generate a small electrical current. This is one instance of organisms being combined with non-living material to provide energy.
However, no one has attempted to replace the electrolyte of a battery with a live fungal species . . . until now.
