2. Recycling of nickel metal hydride (NiMH) batteries; Characterization and recovery of nickel, AB5 alloy and cobalt
Abstract : Nickel metal hydride (NiMH) batteries are used today for applications that can assist in the adaptation toward carbon-neutral energy sources (i.e. hybrid vehicles and smart grids). Recovery of metals such as nickel, cobalt and rare earth elements (REEs) from discarded NiMH batteries is important for economic and/or technological reasons. READ MORE

3. Development of metal hydride surface structures for high power NiMH batteries : Also extended cycle-life and lead to more effective recycling methods
Abstract : By combining alkaline etching of hydrogen storage alloys or their hydrides with a controlled oxidation, it was possible to improve reaction kinetics and accelerate activation of MH-electrodes. Both AB5 and AB2 alloys were studied where A is mixtures of rare earth elements for AB5 alloys and titanium and/or vanadium, zirconium for AB2 alloys; nickel contributes the major part of B.
