Detrimental MnPO<sub>4</sub>F and MnF<sub>2</sub> formation on LiMn<sub>2</sub>O<sub>4</sub> in the 3 V region
Louis De Taeye, Philippe M. Vereecken
Abstract
The 3 V region of LMO is inhibited when using LiPF 6 based electrolytes, due to the formation of a LiF/MnF 2 decomposition layer. This layer is formed by direct interaction between LiPF 6 and Li 2 Mn 2 O 4 , as demonstrated using a thin-film model electrode.
