"reidentified residual Li compound location/ minimized residual lithium content... High-Ni cathode content increases energy density, but leads to gelation, excessive residual lithium compounds not only on surface, but also between internal high-Ni cathode particles... overcome using single-crystal high-Ni having minimal or no grain boundaries between primary particles, preventing interparticle gap formation, eliminating space where residual lithium compounds could crystallize, reducing their levels up to 54%, to below 2K ppm"
