Specifically for Li3M(III)Cl6 (M(III)= Bi, Dy, Er, Ho, In, Lu, Sc, Sm, Tb, Tl, Tm, Y), the influence of the M(III) in different chlorides on the high voltage stability was calculated to be between 4.26-4.38 V, the majority at 4.26 V vs Li/Li + (ref. ). Recent experimental results, showed that the difference between different M(III)/M(IV) is larger than expected, and that not only the electrochemical stability is relevant in such systems, but also the stability against oxygen release especially in combination with high capacity LiNi0.85Co0.1Mn0.05O2 (ref. ).
