• Mycelium might power electronics someday, if it stops biodegrading before the job is done
• The split-gill mushroom’s extracellular matrix may be the key to future green batteries
• Scientists dream of compostable batteries, but controlling fungal behavior remains a major challenge

Researchers from Empa, the Swiss Federal Laboratories for Materials Science and Technology, are exploring the potential of fungal mycelium to create a compact, biodegradable battery.

Their goal is to use mycelium to produce “fungal paper” for battery electrodes – a concept that, according to researcher Ashutosh Sinha, remains in the experimental phase.
