This study investigates the current efficiency (CE) of aluminium electrolysis in modern cells, focusing on the impacts of electrolyte composition and operational temperature. The objective is to analyze how these factors influence CE, particularly in relation to the loss of efficiency caused by back reactions between dissolved aluminium and anode products. To accomplish this, a laboratory cell was modified to ensure more reliable measurements of current efficiency through controlled electrolysis at constant current density, with subsequent evaluation of deposited aluminium weight. Various electrolyte compositions, including the addition of LiF, were considered alongside temperature variations. The results indicate a strong correlation between current efficiency and the content of dissolved metal within the electrolyte, highlighting that lower cryolite ratios and strategic LiF additions can enhance overall current efficiency in electrolysis processes. This research contributes valuable insights to optimizing the Hall-Héroult process for industrial aluminium production by establishing important parameters that influence operational efficiency.
