PERFORMANCE OF AB, ALLOYS FOR HYDROGEN STORAGE AND HYDRIDE ELECTRODES
Two types of hydride electxodes are potential candidates to replace the Cd elecsode in NilCd batteries, One is of the A type where A is a rare earth metal or mixture thereof, and B is the transition metal. The other is commonly referred to as A type. A , type alloys with partial substitution of the B element in A type hydride material (Ovonic) with Co, Mn, Al, and Fe were studied (A compo...
متن کاملSuperior hydrogen storage in high entropy alloys
Metal hydrides (MHx) provide a promising solution for the requirement to store large amounts of hydrogen in a future hydrogen-based energy system. This requires the design of alloys which allow for a very high H/M ratio. Transition metal hydrides typically have a maximum H/M ratio of 2 and higher ratios can only be obtained in alloys based on rare-earth elements. In this study we demonstrate, f...
متن کاملProcess analysis of electroless copper plating for AB5- type hydrogen storage alloy using support vector regression
Surface modification is an effective method to improve the electrochemical property of hydrogen storage alloy. In order to investigate the influence of process factors of electroless copper (Cu) plating for AB5-type hydrogen storage alloy on Cu coating mass, a novel modeling approach, support vector regression (SVR) combined with particle swarm optimization (PSO), was proposed to construct a ma...
متن کاملNanocrystalline hydrogen storage alloys for rechargeable batteries
AB -type intermetallic compounds were prepared by the melt spinning method. Structure analysis was carried out by X-ray 5 diffractometry, SEM and high resolution electron microscopy. The hydrogen storage capacity was determined by isothermic mass controlled absorption of hydrogen and by electrochemical charge /discharge cycles. A variation of the preparation parameters showed that a nanocrystal...
