Microstructural aspects of manganese metal during its electrodeposition from sulphate solutions in the presence of quaternary amines

Highlights
- Quaternary amines produced smooth and bright manganese electrodeposits.
- TEABr produced smooth and bright deposits with euhedral shaped crystals.
- TBABr produced dendritic deposits with elongated poly-nodular crystals.
- All the quaternary amines behaved as cathode polarisers.
- TEABr was found to be the most efficient organic additive.
