Wooden Rechargeable Batteries

Researchers synthesize battery cathode from plant lignin derivatives, which today are mostly made from nonrenewable metals such as lithium or lead.

It may sound completely unreal but scientist Grzegorz Milczarek from Poznan University of Technology in Poland and Olle Inganäs from Linköping University in Sweden have been whittling away at the possibilities of creating a new type of low-cost, Earth-friendly rechargeable battery from wood waste.
Researchers combined a polymer with lignin, a waste material from the paper mills, to create a new kind of battery cathode.

Every battery has 2 electrodes: anode and cathode and are filled with an electrolyte. The aggregate result of the chemical reactions taking place within the electrolyte creates a flow of electrons between two electrodes, resulting in the release of electricity.
Electrolytes are often made of basic and no expansive chemicals. The electrodes, however, are not. They are made from nonrenewable metals such as lead, zinc, nickel, cobalt or lithium, and their cost can be prohibitively expensive.
Less expensive electrodes would be a potentially significant change in all areas of energy supply and energy consumption and that is what Dr Milczarek and Dr Inganas hope they have created.

A good cathode material must be capable of receiving and storing charge (in the form of positive ions and electrons) in large amounts and according to the scientists, whose research appears in the March 23 issue of Science, the new renewable battery cathode made of lignin combined with a polymer known as “polypyrrole”, effectively holds an electric charge.

“The advantage of using a renewable material for charge storage is the enormous amount of this material that is already being produced on Earth by growing plants, which contain about 20 to 30 percent lignin,” Inganäs says. “It is also a low-value material, currently being used for combustion. Lithium-ion batteries, on the other hand, require metal oxides and some of those materials, such as cobalt, are rather rare.”

Lignin is the second most common polymer produced in nature by living organism (the most common being cellulose.) And lignin is inexpensive. Paper is made generally of cellulose, the other component of wood, so the effluent from paper mills, known as brown or black liquor, is mainly water and lignin.
The reason Dr Milczarek and Dr Inganas believed lignin molecules might be suitable for use as cathodes was that they are rich in chemical groups called phenols, and phenols are very easily turned into quinones. It is these quinones that are the essential components. In combination with a polypyrrole, they provide just the sort of electron and proton receptors a cathode requires.

The two researchers’ findings suggest that the lignin-polypyrrole combination makes an effective cathode, able to store a lot of charge.

While the whole technology is still at it’s earliest stages, we could see the use of lignin batteries in our lifetime as we keep utilize our natural resources for renewable energy.

  1. What’s up, its good post on the topic of media print, we all understand media is a fantastic source of information.

  2. detox now says:

    It is always just so refreshing to see decent content like this considering the unnecessary content that’s out there. I mean, you can definitely tell that much time and patience with into this. Do you use content writers or do you create your own material?

  3. detox fast says:

    Excellent material compared to some of the other topics I’ve read. Continue the nice work.

  4. mandi1238 says:

    This wasn’t the site I was looking for however I’m glad I found it. I see it’s very popular on the web. Good job.

  5. mitzi3669 says:

    You can hardly find posts like this nowadays. I recall when you could find a few topics like this in minutes however now it’s much harder.

  6. russell7105 says:

    The following is great content. Among the best posts I’ve come across at present. Continue the good work.

  7. shandra5356 says:

    It is evident that this write-up is one of the finest I have found today. It’s also apparent the individual who’s website this is put alot of work in it. Great job!

  8. edyth6684 says:

    Wonderful entry. Among the best I’ve come across.

  9. florance832 says:

    I think I read a different post similar to this one in before. It seemed to be the exact same subject matter and is just as well written.

  10. tracee1733 says:

    Based on the number of responses, this is definately a truly engaged topic. Whenever I come back to this post there’s an interesting visitor post better than many of the earlier ones.

  11. jennine6633 says:

    If I can find more content like here, that would be great.

  12. delinda5421 says:

    You scarcely come across content like this anymore. I remember when you could find a few posts similar to this in less than 10 minutes however now it’s substantially more difficult.

  13. summer8171 says:

    This unique post is quite engaging. I may certainly be coming back to your site.

  14. maryetta8876 says:

    I’ve got to admit this is one of many exceptional postings I’ve found about this topic. I am going to definately follow your posts.

  16. arnoldo8981 says:

    Now i’m actually glad I stumbled upon this post. It’s well written plus the subject material is great. I hope to find more like this.

  17. It can be difficult and a little bit risky for the kids to travel
    with the weather unexpectedly changing always.
    Prioritizing a clean driving record will make the lowest prices attainable for
    your rating class. Respected companies like Hyundai,
    Toyota, Holden etc have presented series of small cars to pick from
    making the task more difficult.

  18. brand says:

    great site, thanks

    Green as in environmentally friendly, all natural, nature inspired, nature made ingredients, organic products?

    You know as in beauty and grooming products, household cleansers stiff like that.
