Electrochemical evaluation of anodes in lead electrowinning
<p>"The recovery of lead from scrap batteries using hydrometallurigical techniques requires a chemically stable and electrochemically attractive anode in the electrowinning step. A high reaction rate of oxygen evolution and a low generation of lead dioxide are necessary to ensure a satisfactory …

Characterising Electrolyte Interactions with Carbon Anodes for Sodium Ion Batteries
… hard carbons that are normally used as anodes, albeit to a lesser extent than in graphite. Chapter 4 sets out to probe the dynamics of diglyme co-intercalated into hard carbon using 2H NMR and simulations, and then use the dynamics of diglyme as an indirect probe for the structure of …

The Local Structure of Sodium-Ion Anodes During Electrochemical Reactions
… apply this novel multi-modal approach to tin anodes. We find that sodium insertion begins by conversion into NaSn$_2$, a phase consisting of stanene layers separated by sodium ions. This is then broken down into an amorphous phase, where reverse Monte Carlo refinements show that the …
