Recent research at Purdue University has suggested their potential use as anodes in lithium-ion batteries. The Journey of Pollens: From Allergens to Anodes "Our findings have demonstrated that renewable pollens could produce carbon architectures for anode applications in energy storage devices," said Vilas Pol, an associate professor in the School of Chemical Engineering and the School of Materials Engineering at Purdue University.
Batteries have two electrodes, called an anode and a cathode. Lithium ions are contained in a liquid called an electrolyte, and these ions are stored in the anode during recharging. The researchers tested bee pollen- and cattail pollen-derived carbons as anodes.
Whereas bee pollen is a mixture of different pollen types collected by honey bees, the cattail pollens all have the same shape.
But the idea of using them as battery anodes did not really kick in until I started working on battery research and learned more about carbonization of biomass.
They were further processed, or "activated," by heating at lower temperature - about degrees Celsius - in the presence of oxygen, forming pores in the carbon structures to increase their energy-storage capacity.
The research showed the pollen anodes could be charged at various rates. While charging for 10 hours resulted in a full charge, charging them for only one hour resulted in more than half of a full charge, Pol said.
The researchers tested the carbon at 25 degrees Celsius and 50 degrees Celsius to simulate a range of climates. Findings showed the cattail pollens performed better than bee pollen. The work is ongoing. Whereas the current work studied the pollen in only anodes, future research will include work to study them in a full-cell battery with a commercial cathode.View the profiles of professionals named rutadeltambor.com on LinkedIn.
