Over the past decade, extensive research has focused on developing catalysts that enhance selectivity and reduce the overpotential of CO<sub>2</sub>RR. However, further attention should be directed towards the design of electrolyzers and integrated systems to achieve high current densities, improved energy efficiency, carbon efficiency, and stability.

In H-cells, the relatively low solubility of CO<sub>2</sub> in aqueous electrolytes limits current density, and strategies to enhance CO<sub>2</sub> mass transport are discussed. For GDE-based flow cells, strategies to maintain the hydrophobicity of GDEs are examined. Additionally, the impact of pH and alkali cations on energy efficiency, carbon efficiency, and anti-flooding performance is reviewed.

The introduction of electrode materials into the high-entropy strategy has improved the cycling performance of batteries, so the corresponding high-entropy electrolytes (HEEs) have high research value due to their disordered structure.

However, developing a structurally strong electrolyte is a significant challenge, as high mechanical strength often leads to reduced ionic conductivity.
