Fabrication and electrochemical properties of cylindrical hybrid supercapacitor using H2Ti12O25 as anode material

The preparation of H2Ti12O25 via multi-method and their rate performance in Lithium ions battery

“…Furthermore, hybrid supercapacitor using H 2 Ti 12 O 25 exhibited a better cycle performance than that of Li 4 Ti 5 O 12 [5] . All these studies suggest that H 2 Ti 12 O 25 can be used as a novel and promising anode material, due to its high capacity and excellent cycle performance.…”

“…The obtained H 2 Ti 12 O 25 particle became much smaller and its initial capacity increased to 229 mAh g -1 under the same test condition [4] . A very recent report about H 2 Ti 12 O 25 was published by Lee et al [5] in 2014. Here, H 2 Ti 12 O 25 was used as anode in hybrid supercapacitor and exhibited higher specific capacitance (57 Fg -1 ) than Li 4 Ti 5 O 12 (38 Fg -1 ) [5] .…”

“…Currently, Na 2 Ti 3 O 7 precursor for synthesizing H 2 Ti 12 O 25 is usually prepared by solid state reaction [3][4][5][6] . Nagai et al [6] reported that Na 2 Ti 3 O 7 precursor with small particle size can be prepared by solid state reaction and grinding.…”

Enhanced electrochemical performances of cylindrical hybrid supercapacitors using activated carbon/ Li 4-x M x Ti 5-y N y O 12 (M = Na, N = V, Mn) electrodes

“…Because supercapacitors are based on a simple energy storage mechanism that involves adsorptionedesorption at the surface of the high surface area activated carbon. Therefore, hybrid supercapacitors consisted of different cathodes and anodes having different operating potentials and principles for realizing the capacitances [10]. The concept of the proposed hybrid supercapacitor is shown in Fig.…”
