摘要
High-temperature technologies like solid oxide cells (SOC) have been employed to provide power-to-fuel and vice versa for energy conversion and storage. These technologies are a work in progress due to durability and compatibility issues between components at high temperatures. For this reason, the pursuit of optimal physical, mechanical, and chemical properties of SOC materials at lower temperatures has become more diligent. Finding suitable air electrodes has become one of the more notable obstacles to complete implementation in the industry. One of the most recent alternatives is the use of lanthanide nickelates with the Ruddlesden-Popper (RP), Lnn+1NinO3n±1 (Ln = La, Nd or Pr), and perovskite, LnNiO3-δ, structures. These materials present fast ionic and electronic transport, as well as flexible oxygen stoichiometry that makes them compelling for this purpose. As part of an ongoing study on alternative air electrode advanced materials, this review is focused on documenting the relevant findings of RP nickelates over the years, especially focusing on the current status in research and development while comparing the electrochemical performance of nickelate air electrodes.
