“…10,11 Among these materials, carbon nanotubes (CNTs) have been considered ideal for electrochemical capacitors, owing to the advantages such as accessible surface area, excellent electronic conductivity, and good stability. [12][13][14][15][16][17] On the other hand, CNT grows the polarization when CNT electrode reacts with electrolyte through the electrode/electrolyte interface. Generally, polarization is the change of potential of an electrode from its equilibrium potential upon the application of a current.…”

To reduce polarization of electrochemical capacitor based on carbon nanotube, titanium oxide nanoparticles were deposited by ultrasound. The pore distribution of TiO2/CNT nanoparticle exhibited surface area of 341 m 2 g -1 when TiO2 content was 4 wt %, which was better than that of pristine CNT with surface area of 188 m 2 g -1 . The analyses indicated that titanium oxide (particle diameter < 20 nm) was deposited on the CNT surface. The electrochemical performance was evaluated by using cyclic voltammetry (CV), impedance measurement, and constant-current charge/discharge cycling techniques. The TiO2/CNT composite electrode showed relatively better electrochemical behaviors than CNT electrode by increasing the specific capacitance from 22 Fg -1 to 37 Fg -1 in 1 M H2SO4 solution. A symmetric cell assembled with the composite electrodes showed the specific capacitance value of 11 Fg -1 at a current loading of 0.5 mAcm -2 during initial cycling.

With the emerging technology in the 21st century, which requires higher electrochemical performances, metal oxide composite electrodes in particular o®er complementary properties of individual materials via the incorporation of both physical and chemical charge storage mechanism together in a single electrode. Numerous works reviewed herein have identi¯ed a wide variety of attractive metal oxide-based composite electrode material for symmetric and asymmetric electrochemical capacitors. The focus of the review is the detailed literature data and discussion regarding the electrochemical performance of various metal oxide composite electrodes fabricated from di®erent con¯gurations including binary and ternary composites. Additionally, projection of future development in hybrid capacitor coupling lithium metal oxides and carbonaceous materials are found to obtain signi¯cantly higher energy storage than currently available commercial electrochemical capacitors. This review describes the novel concept of lithium metal oxide electrode materials which are of value to researchers in developing high-energy and 1430002-1 NANO: Brief Reports and Reviews Vol. 9, No. 6 (2014) enhanced-cyclability electrochemical capacitors comparable to Li-ion batteries. In order to fully exploit the potential of metal oxide composite electrode materials, developing low cost, environment-friendly nanocomposite electrodes is certainly a research direction that should be extensively investigated in the future.
