Mushrooms to power SmartPhones!

Researchers at University of California have created a new type of lithium ion battery anode using portabella mushrooms which are environmental friendly, inexpensive and easy to produce.

This battery which is being derived from Nanocarbon Architectures based on biological materials like mushrooms can be considered all-green and can act as a sustainable alternative to the usual Graphite-based anodes.

Presently, synthetic graphite is acting as an industry standard for rechargeable lithium-ion battery. But it comes at a high cost, as it has to go through immense purification and preparation process that also affect negatively on environment.

Whereas, if a high carbon content biological material from living or a dead organism is used a replacement for graphite, then low cost and environmental friendliness can be gathered in an efficient way.

Mushrooms have highly porous surface making them ideal to store liquid or air to pass through. That porosity is important for batteries because it creates more space for the storage and transfer of energy, a critical component to improve battery performance.

Moreover, Mushrooms are super rich in high potassium salt concentration and it acts as an electrolyte active material over time by activating more powers, gradually increasing its capacity. A conventional anode allows lithium to fully access most of the material during the first few cycles and capacity fades from electrode damage occurs from that point on.

A journal will soon be published on this case study by Brennan Campbell who leads the team of professors from Mechanical Engineering and Materials Science and Engineering department at University of California, Riverside, USA.
