New ways of making life easier and help the environment, is created every day. Researchers have been able to make new type of lithium-ion battery anode using portabella mushrooms which is very eco-friendly and inexpensive, a latest battery technology
All batteries use perishable sources but getting biomass, a biological material from living or recently living organisms, as a replacement for graphite, has drawn recent attention because of its high carbon content, low-cost and environmental friendliness. Such sources are everlasting and are cheaper than graphite.
Researchers at the University of California, Riverside Bourns College of Engineering have together created highly porous (for transfer of air and liquid) material .the porosity is important for batteries because it creates more space for the storage and transfer of energy very important for improving battery performance.
What we often see is that there is a decrease in the efficiency of the battery but high potassium salt concentration in mushrooms later allows the opening of new pores thus increasing capacity. “With battery materials like this, future cell phones may see an increase in run time after many uses, rather than a decrease, due to apparent activation of blind pores within the carbon architectures as the cell charges and discharges over time,” said Brennan Campbell, a graduate student in the Materials Science and Engineering program at UC Riverside.
This type of architecture is known as nanocarbon architecture. The nano-ribbon-like architectures when heated, transform into an interconnected porous network architecture which increases capacity of the battery because of its large surface area.
All the daily batteries we use now are made up of expensive graphite components and the manufacturing process is not at all eco-friendly. Therefore, the UC Riverside team is focused on naturally derived carbons, such as the skin of the caps of portabella mushrooms, for making batteries.
A forecast has been made that due to the excessive use of batteries increasing day by day nearly 900,000 tons of natural raw graphite would be needed for anode fabrication by 2020. The research team is working on the development of pouch prototype batteries based on nano silicon anodes. This latest battery technology get a hats off for sure.
