The observed dynamical lattice trifurcation due to coexistance of phases in a single crystal could have important implication on the electrochemical performance of LMNO cathode material. The irreversible plastic change of the lattice misorientation caused by this phenomenon after the charge-discharge cycle suggests a possibility of accumulation of such deformations. A number of studies have investigated the detrimental effects of grain boundaries in solid-state electrolytes and polycrystalline cathodes such as decreased conductivity, increased possibility of cracking and facilitation of degradation. Since grain boundaries can be considered as an extreme case of low-angle tilt boundaries, some negative characteristics can be expected from the tiltboundaries albeit to a lesser extent due to much lower lattice misorientation. The dynamic formation of a tilt boundary suggests an increase of defect concentration in its vicinity which lowers the energy of the boundary. However the density of the defects at the grain boundary is decreased due to the accommodation of lattice mismatch between different phases. This increase of defect concentration could limit the kinetics of Li ions and thus increase the resistivity of the tilt boundary. Indeed the intensity maps demonstrate an apparent increase of the diffracting volume in the center of each of the three domains and a gradual decrease towards the borders (Figures and). This signifies that Li deintercalation in each individual misorientated domain proceeds to a certain degree independently due to a kinetic constraint of lithium deintercalation through tilt boundaries.
