Wild mushrooms have recently made a surprising (but not unwelcome) foray into the battery realm.

In a new study, researchers from Purdue University derived promising carbon fibers from a wild mushroom and modified them with nanoparticles to cook up new battery anodes that outperform conventional graphite electrodes for lithium-ion batteries.

Outperforming traditional anodes

“Current state-of-the-art lithium-ion batteries must be improved in both energy density and power output in order to meet the future energy storage demand in electric vehicles and grid energy-storage technologies,” said Vilas Pol, ECS member and associate professor at Purdue. “So there is a dire need to develop new anode materials with superior performance.”

This from Purdue University:

[The researchers] have found that carbon fibers derived from Tyromyces fissilis and modified by attaching cobalt oxide nanoparticles outperform conventional graphite in the anodes. The hybrid design has a synergistic result.
