Scientists develop anode on the basis of mushroom




US scientists have developed an anode for a lithium-ion battery based on large mushrooms. To show the material of the mushrooms, it proves upon heating porous features that make it useful for the batteries.

The researchers at the University of California, Riverside, used pieces of portobello mushrooms for their research. The mushroom pieces were heated at 500, 700, 900, or 1100 degrees Celsius. The biomass is a carbon nano-strip-like structure and when heated above 900 degrees Celsius proved pyrolyzed material ‘hierarchically porous’ to be. The pores hereby ranged in size from nanometers to tens of nanometers, making them the researchers micro, meso and macroporous.

These properties makes the biomass into suitable anode material. Also makes the high concentration of potassium in mushrooms that over time more pores are activated in the material, the scientists suspect, so the capacity gradually increases. When testing with the anode in a button cell battery, was still a capacity of 260mAh / g was observed after 700 charge cycles.
