Abstract: The optimization of the electrolyte composition for a canonical cathode such as LiCoPO 4 olivine. The implemented succinic anhydride within a liquid electrolyte LiPF 6 and dissolved in carbonate/diethyl considerably improves the discharge capacity of the electrode are shown. The introduction of succinic anhydride into the solid/electrolyte interphase (SEI) layer is responsible for the improved electrochemical performance of the electrode. We used LiCoPO 4 @C-ZrO 2 as a cathode to prove the concept. The observed results could be applied for a wide range of cathodes. Moreover, the proposed additive to the electrolyte could help evaluate the performance of the materials without the side effects of the electrolyte.
