Scientists use mushrooms for new batteries to power cell phones, electric vehicles

The porosity of portabella mushrooms, the researchers said, will improve future batteries and devices with longer performance. The mushrooms also have high potassium salt concentration, which can help increase the capacity of rechargeable batteries. “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,” said Brennan Campbell, a graduate student in the Materials Science and Engineering programme at UC Riverside.
