Batteries – Interfacial chemical reactions and stability in 5V Lithium Ion Cells

Our research published recently in demonstrates a high stability of LiCoPO4 tailored with LiCo2P3O10 (LCP-LCPO) as cathode material for Li-ion batteries upon electrochemical cycling to 5.1 V vs. Li+/Li. In contrast, the MoO3 coating layer on the top of the LCP−LCPO cathode undergoes chemical reactions with the electrolyte resulting in leaching of the oxide layer. ACS Applied Materials and Interfaces
