Abstract: One embodiment is a redox flow battery system that includes an anolyte; a catholyte; an anolyte tank configured for holding at least a portion of the anolyte; a catholyte tank configured for holding at least a portion of the catholyte; a primary redox flow battery arrangement, and a second redox flow battery arrangement. The primary and secondary redox flow battery arrangements share the anolyte and catholyte tanks and each includes a first half-cell including a first electrode in contact with the anolyte, a second half-cell including a second electrode in contact with the catholyte, a separator separating the first half-cell from the second half-cell, an anolyte pump, and a catholyte pump. The peak power delivery capacity of the secondary redox flow battery arrangement is less than the peak power delivery capacity of the primary redox flow battery arrangement.

Abstract: What is disclosed is an electrode material including a sintered body containing a heat resistant element and Cr and being infiltrated with a highly conductive material. A powder mixture of a heat resistant element powder and a Cr powder is subjected to a provisional sintering in advance, thereby causing solid phase diffusion of the heat resistant element and Cr. After a Mo—Cr solid solution obtained by the provisional sintering is pulverized, the pulverized Mo—Cr solid solution powder is molded and sintered. A sintered body obtained by sintering is subjected to a HIP treatment. The highly conductive metal is disposed on the sintered body after the HIP treatment, and infiltrated into the sintered body by heating at a predetermined temperature. By conducting the HIP treatment, the withstand voltage capability and current-interrupting capability of the electrode material are improved.

Abstract: The present invention relates to a high entropy alloy having more improved mechanical properties by controlling contents of additive elements in a NiCoFeMnCr 5-element alloy to control stacking fault energy, thereby controlling stability of a γ austenite phase to control a transformation mechanism, wherein the stacking fault energy is controlled in a composition range of NiaCobFecMndCre (a+b+c+d+e=100, 1≦a≦50, 1≦b≦50, 1≦c≦50, 1≦d≦50, 10≦e≦25, and 77a−42b−22c+73d−100e+2186≦1500), and thus, the γ austenite phase exhibits a twin-induced plasticity (TWIP) property or a transformation induced-plasticity (TRIP) property in which the γ austenite phase is subjected to phase transformation into an ε martensite phase or an α′ martensite phase, under stress, thereby having improved strength and elongation at the same time to have excellent mechanical properties.

Abstract: A process for producing an electrode material by infiltrating a highly conductive metal such as Cu into a porous object containing heat-resistant elements. Before an infiltration step in which the highly conductive metal is infiltrated, a HIP treatment is given to a powder containing the heat-resistant elements (or to a molded object obtained by molding a powder containing the heat-resistant elements). The composition is controlled so that the HIP treatment yields a porous object which has a degree of filling of 70% or higher, more preferably 75% or higher. The highly conductive metal is infiltrated into the porous object having the controlled composition.
