- Abstract
- We have demonstrated an effect of UV/O3 treated carbon black on the dispersion properties of LiCoO2 ink and the resulting electrochemical properties of ink-jet printed LiCoO2 positive electrodes. The dispersion properties of UV/O3 treated carbon black and LiCoO2 ink are evaluated by particle size distribution measurement, surface pressure measurement, and scanning electron microscope observations. We found that UV/O3 treatment makes carbon black functionalized surface and improved the dispersion properties of carbon black and LiCoO2 ink. The electrodes prepared with UV/O3 treated carbon black have a denser and more homogeneous microstructure and lower surface rms values, compared to those with as-received carbon black. The electrochemical performance of ink-jet printed LiCoO2 positive electrode with UV/O3 treated carbon black shows high initial coulombic efficiency (89%) and specific discharge capacity (128 mAh?g-1) due to homogeneous distribution of carbon black around each LiCoO2 and better electrical contact between carbon black and LiCoO2.
