A new research paper published few months ago in the journal Nature Scientific Reports, suggests that the industry standard of synthetic graphite used in lithium-ion batteries, may one day be replaced by mushrooms.
The research team at the University of California, has shown that the anode of lithium-ion battery could be developed using the highly porous portobello mushroom (Agaricus bisporus), which is less expensive and more efficient to produce.
Currently, battery performance decreases over time due to the chemical process that wears out the cathode. A lithium-polymer battery can lose about 20 percent of its capacity after around 1000 charge cycles. With the use of portobello mushrooms as a battery material, future electronics may have the capability of increasing the run time after many cycles, in contrast to the decreasing run times of current electronics.
