This study explores effective methods to extend electrode lifespans under harsh electrolysis conditions, such as high current densities, acidic environments, and impure water sources. The researchers developed an alternating electrolysis approach that involves regular and prompt maintenance and bubble evolution. The key finding is that the co-action of Fe group elemental ions (Fe, Co, Ni, Mn) and alkali metal cations (Na+, K+, Li+) significantly improves electrode durability, particularly with a unique combination of Co2+ and Na+. A commercial Ni foam electrode, which is susceptible to dissolution in acidic conditions, was used as a substrate. Under alternating electrolysis conditions, this electrode sustained electrolysis for 93.8 hours in an acidic solution, a significant improvement over conventional electrolysis conditions where it would dissolve within 2 hours. The study also highlights the potential of alternating electrolysis-based systems, alkali metal cation-based catalytic systems, and electrodeposition techniques for prolonged electrolysis through repeated deposition-dissolution processes. The results demonstrate the feasibility of using non-noble metals to achieve long-term electrolysis under harsh conditions, with the upper limit of electrode lifespan potentially being high. The work not only advances the understanding of water electrolysis but also opens new avenues for developing sustainable energy technologies.This study explores effective methods to extend electrode lifespans under harsh electrolysis conditions, such as high current densities, acidic environments, and impure water sources.
