| Sumario: | Electrochemical lithium extraction methods have recently attracted significant attention as alternatives to the currently employed techniques. A considerable effort has been made to develop this technology, especially in searching Li-ion selective electrodes. However, much less attention has been paid to the counter electrodes. In general, these materials have been used as counterparts without considering their influence in the global method. This review summarizes the counter electrodes, analyzing their pros and cons. In addition, the energy efficiency of the various configurations was reported, while the other performance indices were not included because of the lack of data provided in the literature. Nevertheless, their potential influence in crucial parameters like purity, efficiency, or stability was estimated based on their electrochemical properties. This review demonstrates that specific studies on the counter electrodes and an effort to develop alternative materials are needed to push the current electrochemical lithium extraction method toward a new level. |
