Lithium-excess 3d-transition-metal layered oxides (Li<sub>1+x</sub>Ni<sub>y</sub>Co<sub>z</sub>Mn<sub>1-x-y-z</sub>O<sub>2</sub>, >250 mAh g<sup>-1</sup>) suffer from severe voltage decay upon cycling, which decreases energy density and hinders further research and development. Nevertheless, the lack of understanding on chemical and structural uniqueness of the material prevents the interpretation of internal degradation chemistry. Here, we discover a fundamental reason of the voltage decay phen ...[more]
