The current shortage of green energy supply to meet the growing demand for aluminiumAluminium , together with a requirement to lower their Carbon footprintCarbon footprint , is driving smelters to shift to a high productivity, minimum energy cell operation while targeting minimum anodeAnode consumption. The anodeAnode shape, size, and setting pattern in the cells all have an impact on both the energy efficiency and net carbonCarbon consumption. Slots have been introduced to lower the resistance of the electrolyte. This has enabled increases in cell line current, but there has been a consequential reduction in the anodeAnode to cathodeCathode distance and electrolyte volume. Slots have also reduced the driving force for electrolyte flow and mixing. Increasing anodeAnode mass in the cells has resulted in longer times for the anodeAnode to heat up and draw full current. Thus these changes have introduced greater spatial variation in cell conditions, which have impacted cell performance. This paper aims to open up discussion toward determining the ideal anodeAnode design for smelters beyond the year 2020.
