Electrochemically induced deposition of functional metal phosphates for energy storage and conversion

The concept of my master thesis was to use water reduction to form an increased hydroxide concentration near the electrode surface, which allows phosphate to deprotonate and, in turn, Li3PO4 precipitate and form a passivating layer on the electrode. For the PhD research, a similar approach will be used to deposit nickel-manganese-oxides (NMOs). By reducing Mn(OH)2 to Mn, an increased concentration of hydroxide will form near the surface, and this is expected to cause nickel hydroxide to precipitate. As the reaction proceeds, the plating of Mn is expected to occur in parallel with the precipitation of nickel hydroxide, and thus we expect that a manganese-nickel-hydroxide layer will form, which can be annealed to a NMO layer. This NMO layer is of interest as it has applications within energy storage, more specifically Li-ion batteries.
