“Blood Batteries”

By Brandon Brunelle


What is it l.jpg

What is it?

  • An energy source that can run off of an array of electrolytes including bodily fluids..

  • safe

    ultrathin

    flexable

    durable


Needs l.jpg

Needs

  • The goal is to build a hybrid of a battery and super capacitor in one entity.

  • Super capacitor:

    • Large discharge

    • Electrolytes; either aqueous or solid, are used to separate plates.

  • Battery

    • Electro chemical cells used to store and convert chemical energy


  • Technology l.jpg

    Technology

    • Nanocomposite paper (CNT cellulose–RTIL)

      • Multiwallednanatubules(MWNT) are grown on silicon substrate.

      • Plant cellulose dissolved in RTIL is infiltrated into MWNT

      • The resulting film is cleaned using ethanol and then set on dry ice to remove ethanol.

      • On the order of 10 microns thick.

      • Remarkable bending and twisting ability without deformation

      • Cellulose is randomly porous anywhere between 45 and 55nm between pores. Pore density can be increased or decreased.


    Design l.jpg

    Design

    • MWNTs serve the purpose of electrodes.

    • Cellulose acts as the insulator

    • RTIL as the self sustaining electrolyte

    • Two nanocomposites are used to create supercapacitor


    Results l.jpg

    Results

    • Record breaking operating temperature of 195K-423K

    • Different aqueous and nonaqueous electrolytes were used.

    • Device was tested at 77K

    • The device was found to work when compounds such sweat and blood were used as the electrolyte

    • Development of flexible lithium ion battery was also designed.


    Conclusion l.jpg

    Conclusion

    • Uninteruptable durable energy source

    • Can be adapted to operate medical devices

    • Cost effective

    • Good future ahead
