“With battery materials like this, future cell phones may see an increase in run time after many uses, rather than a decrease, due to apparent activation of blind pores within the carbon architectures as the cell charges and discharges over time”, says researcher...

In addition, because of the high potassium salt concentration, the battery was found to be much more durable and much less prone to deterioration. Mushroom-based batteries may even answer the problem of energy storage degradation for frequently recharged electronics like cell phones.

This diagram illustrates how mushrooms are turned into a material for battery anodes.
