    Monoclinic NaNiO[subscript 2] is re-investigated as a positive electrode material for sodium ion batteries. We observe reversible Na extraction and insertion of about 120 mAh/g when NaNiO[subscript 2] is cycled between ...
  • Chiang, Yet-Ming; Carter, W. Craig; Woodford, William Henry (The Electrochemical Society, 2010-08)
    Fracture of electrode particles due to diffusion-induced stress has been implicated as a possible mechanism for capacity fade and impedance growth in lithium-ion batteries. In brittle materials, including many lithium ...
  • Lee, Seok Woo; Yang, Yuan; Lee, Hyun-Wook; Ghasemi, Hadi; Kraemer, Daniel; Chen, Gang; Cui, Yi (Nature Publishing Group, 2014-05)
    Efficient and low-cost thermal energy-harvesting systems are needed to utilize the tremendous low-grade heat sources. Although thermoelectric devices are attractive, its efficiency is limited by the relatively low ...
  • Ong, Shyue Ping; Andreussi, Oliviero; Wu, Yabi; Marzari, Nicola; Ceder, Gerbrand (American Chemical Society, 2011-05)
    We investigated the cathodic and anodic limits of six room-temperature ionic liquids (ILs) formed from a combination of two common cations, 1-butyl-3-methylimidazolium (BMIM) and N,N-propylmethylpyrrolidinium (P13), and ...
  • Biesheuvel, P. M.; Fu, Yeqing; Bazant, Martin Z. (SP MAIK Nauka/Interperiodica/Springer-Verlag, 2012-06)
    We present porous electrode theory for the general situation of electrolytes containing mixtures of mobile ions of arbitrary valencies and diffusion coefficients (mobilities). We focus on electrodes composed of primary ...
  • Sokhanvaran, Samira; Lee, Sang-Kwon; Lambotte, Guillaume; Allanore, Antoine (Electrochemical Society, 2015-12)
    The electrolytic extraction of liquid copper at 1105°C from a molten sulfide electrolyte composed of 57 wt% BaS and 43 wt% Cu[subscript 2]S was investigated. DC cyclic voltammetry, Fourier transformed AC voltammetry, and ...
  • Ruan, Shiyun; Schuh, Christopher A. (Elsevier B.V., 2009-05)
    Al–Mn alloys with Mn content ranging from 0 to 15.8 at.% are prepared by electrodeposition from an ionic liquid at room temperature, and exhibit a remarkably broad range of structures. The alloys are characterized through ...
  • Ziano, Roberto; Salerno, Domenico; Mantegazza, Francesco; Bazant, Martin Z.; Brogioli, Doriano; Rica, Raul A. (Elsevier, 2013-01)

  • Rica, Raul A.; Bazant, Martin Z. (American Institute of Physics, 2010-11)
    Colloidal particles in electrolytes move in response to electric fields (electrophoresis) and salt concentration gradients (diffusiophoresis), and related flows also occur at fixed surfaces (electro-osmosis and diffusio-osmosis, ...
