A green and automatic recycling separation process to recycle LiCoO2 cathodes from laptop batteries was designed. Prior to that, an exhaustive study of the main chemistry used for laptop batteries was undertaken, analyzing the chemical composition of the cathodes of 160 spent batteries from laptops. After concluding that around 70% of the spent batteries analyzed presented LiCoO2 as the cathode active material, regeneration experiments were undertaken to recover the LiCoO2 to be able to be used in the manufacture of new laptop batteries. The influence of the cathode separation process was addressed, studying the difference between using a separation method that involves the use of thermal processes and using a separation method that implies the use of an organic solvent. After that, different regeneration methods were compared in order to reach the optimum process to obtain recovered cathodes which chemical, and microscopic structures that lead to the best electrochemical performance.
