Electrochemical properties of lithium air batteries with Pt 100−x Ru x (0 ≤  x  ≤ 100) electrocatalysts for air electrodes

Recent advances in hybrid sodium–air batteries

“…The stabilized composites exhibit long-term cycling stability. Yui et al [146] prepared Pt100−xRux (0≤x≤100) electrocatalysts through the formic acid reduction method. The prepared air electrodes were examined in mol L −1 LiTFSA/TEGDME electrolyte solution (Fig.…”

Electrochemical Properties of Large-Discharge-Capacity Air Electrodes with Nickel Foam Sheet Support for Lithium Air Secondary Batteries

“…Pt 10 Ru 90 /KetjenBlack EC600JD carbon (KB, Lion Co.) was prepared by the formic acid reduction method. 8 The ratio of Pt 10 Ru 90 to KB powder was adjusted to 1:8 by weight. The KB powder was immersed in formic acid solution by ultrasonic treatment.…”

“…Additionally, the inadequate stability of the nonaqueous electrolyte solutions due to oxygen radicals lead to a gradual decrease in discharge capacities during discharge/ charge cycles. Therefore, much work has investigated the airelectrode materials, including the electrocatalyst, [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] and the electrolyte solutions 1,[17][18][19][20][21][22][23][24][25][26] from the viewpoint of improving the battery cycle performance.…”

“…The various kinds of air-electrode materials that have been examined to decrease the large overpotentials for both the electrode reaction of oxygen reduction/evolution include materials with high surface area or porous carbon materials 2,3 and highly active electrocatalysts, such as metal phthalocyanine, 1,4 noble metal alloys (Pt, Ru, Pd and Pt-Ru), [5][6][7][8]10,17 single metal oxides (MnO 2 , Co 3 O 4 , RuO 2 ) [5][6][7][8][9][10][11][12][13][14] and Fe-, Mn-, and Co-based perovskite-type complexed oxides. 15,16 Recently, we have investigated the electrocatalytic activities of Pt 100¹x Ru x (0¯x¯100) for air electrodes.…”

“…15,16 Recently, we have investigated the electrocatalytic activities of Pt 100¹x Ru x (0¯x¯100) for air electrodes. 8 Among these Pt-Ru electrocatalysts, nanometer-scale Pt 10 Ru 90 particles that had been homogeneously dispersed over the KB resulted in superior cycle performances. 8 Moreover, electrolyte solutions, such as dimethyl sulfoxide (DMSO) [17][18][19][20][21] and tetraethylene glycol dimethyl ether (TEGDME), [22][23][24] and ionic liquids, 25,26 have been shown to be stable solutions under LAB operating conditions.…”
