From Allergens to Battery Anodes: NatureInspired, Pollen Derived

During the pollination season, plants can be thought to be minifactories that replie and generate speciesspecific pollen grains. Due to the micrometer particle size of pollens (above 6 μm), considering their shrinkage after pyrolysis they could fall in the range of commerical carbon anode particle sizes. Solid, dense carbon
