Abstract

TiO₂ nanofibers (TNF) are prepared by electrospinning method and they are decorated over the surface of Li[Ni_0.8Co_0.15Al_0.05]O₂ (LNCA) cathodes at three different ratios. The structural, electrochemical, and thermal characteristics of TNF-decorated LNCAs are compared with pristine LNCA. The TNF-decorated LNCA electrodes demonstrate better cycleability and specific capacity than those of the pristine LNCA. Under the current density of a C/10 rate, 1 wt% TNF-decorated LNCA delivers 89.2% and 81.4% of capacity retention at room temperature and elevated temperature, respectively. The onset temperature of thermal decomposition is also shifted towards higher temperature for TNF-decorated LNCA electrodes than pristine LNCA electrodes.
