Electrolyte additives for zinc-anoded secondary cells II. Quaternary ammonium compounds

Quaternary ammonium type derivatives have been examined to assess their efficacy as deposit-enhancing agents in secondary zinc-anoded cells. Simple current—time techniques have been utilised to screen potential alkyl groups and examine their effectiveness. Visual assessment and scanning electron microscopy were also applied to examine the zinc electrodeposits. Two promising additives were then further tested by depositing zinc for a set charge to assess their effect on charging time.
