Pollens, the bane of allergy sufferers, could represent a boon for battery makers: Recent research has suggested their potential use as anodes in lithium-ion batteries.
“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. The anodes in most of today’s lithium-ion batteries are made of graphite. 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.
“Both are abundantly available,” said Pol, who worked with doctoral student Jialiang Tang. “The bottom line here is we want to learn something from nature that could be useful in creating better batteries with renewable feedstock.”
Research findings are detailed in a paper that appeared Friday (Feb. 5) in Nature’s Scientific Reports.
