You a fan of mushrooms food? Surely you know that this one kind of mushroom, portobello mushroom. Yes, it is indeed very delicious mushrooms to be eaten with chilli. This fungus is also often used by vegetarians to replace a portion of the meat when cooking barbecue.
However, did you know that portobello could be a `tool` to charge the phone battery in the future?
Is a scientist working at the University of California Riverside, Brennan Campbell, who initiated the concept of `this baterai` fungus. He revealed that the positive pole (anode) contained in lithium ion batteries in mobile phones today are made of graphite, a material which is very expensive to be reproduced and risk creating toxic waste.
Therefore, Campbell tried to find natural resources that can be used to charge the battery. In the end, he found portobello mushrooms are considered as food biodegradable (recyclable).
Molecular structure in fungi is considered solidly to save energy. In addition, this fungus layer has pores that `pas` to transfer energy efficiently.
Explained further, the graphite material contained in the lithium ion battery is in fact more easily damaged because of the damage caused by electricity. Meanwhile, the content of potassium as well as the concentration of salt content in the portobello mushroom layer capable of increasing the energy capacity that is stable, so it is safe when the overcharge (charging process within a period of excessive).
With material like this, mobile phones in the future will be more secure when in-charge. No longer need to fear if the phone is in-charge within hours, it will not create mold and broken cell phone.
Campbell also has revealed what kind of fungus battery concept that he initiated. Initially, the coating microstructure will didehidrasikan portabello mushrooms at a temperature of 500 degrees Celsius, after which the layer will be transformed into carbon nanoribbons. Afterwards, it will enter the carbon nanoribbons pyrolysis process (described thermochemical) at a temperature of 1100 degrees Celsius and will turn into a porous layer of carbon nanoribbons.
This process is still in the stage further, but if it is true portabello mushrooms could serve as a power source charging the phone battery, preferably mushroom farmers must be prepared to work harder for the future.
