Lithium hydroxide (LiOH) is rapidly becoming the main precursor for layered oxide cathodes used in lithium ion batteries. Current hydrometallurgical method for LiOH production uses substantial amounts of chemicals and creates wastes, leaving behind a negative environmental footprint. Electrodialysis is emerging as a more sustainable technology for LiOH production, effectively eliminating the conventional chemical addition step and its subsequent waste management. Additionally, hydrogen is generated as a by‐product during the electrodialysis process. Various configurations of the electrodialysis cell have been employed to maximize the energy efficiency of the process and the purity of the LiOH product. Nonetheless, this review found that there is a lack of concerted effort in developing ion exchange membranes specific for LiOH production. Current membrane technologies are not tailored to LiOH production, with limited selectivity to lithium in relative to other monovalent cations, as well as relying heavily on harmful perfluoroalkyl (PFA)‐based polymeric membranes. In this review, special attention is given to the state of the art in the testing and development of membranes, i.e., cation and anion exchange membranes, bipolar membranes, as well as novel membranes that are potentially low‐cost, non‐fluorinated, lithium‐selective with high chemical stability and mechanical robustness.

Anode materials play a pivotal role in a wide range of electrochemical applications, including electrolysis, energy storage, corrosion protection, and industrial oxidation processes. This review provides a comprehensive analysis of recent advances in anode materials, with particular emphasis on their structural characteristics and major preparation methods, including thermal decomposition, electrochemical deposition, sol–gel processing, and magnetron sputtering. The degradation behaviour of anodes under electrochemical operating conditions is also critically discussed, together with strategies for improving their durability and overall performance. Particular attention is given to metal oxide-coated anodes, especially those based on ruthenium oxide (RuO₂) and iridium oxide (IrO₂), which remain the most representative systems in dimensionally stable anode (DSA) research and industrial applications. Emerging coating materials, including Co₃O₄- and carbon-based catalysts, are also reviewed as promising alternatives for reducing noble metal usage while maintaining acceptable electrochemical performance. In addition, the role of intermediate layers in titanium-based anodes is examined, with emphasis on their contribution to coating adhesion, conductivity, interfacial stability, and long-term electrode performance. This review further discusses the applications of anode materials in chlorine- and oxygen-related electrochemical industries and evaluates the performance of DSAs in relation to substrate selection, coating composition, and operational requirements. Alternative furnace technologies for anode baking are also reviewed, including conventional furnace heating, laser heating, and microwave heating, together with representative industrial furnace systems such as muffle, continuous, and vacuum furnaces. Overall, this review provides an integrated overview of the current progress in anode material research and development, while highlighting the key challenges and future directions for improving anode efficiency, durability, and sustainability in industrial electrochemical applications.
