      abstract     = {In this study, we have demonstrated that boron doping of
                      Ni-rich Li[NixCoyAl1−x−y]O2 dramatically alters the
                      microstructure of the material. Li[Ni0.885Co0.1Al0.015]O2 is
                      composed of large equiaxed primary particles, whereas a
                      boron-doped Li[Ni0.878Co0.097Al0.015B0.01]O2 cathode
                      consists of elongated particles that are highly oriented to
                      produce a strong, crystallographic texture. Boron reduces
                      the surface energy of the (0 0 3) planes, resulting in a
                      preferential growth mode that maximizes the (0 0 3)
                      facet. This microstructure modification greatly improves the
                      cycling stability; the Li[Ni0.878Co0.097Al0.015B0.01]O2
                      cathode maintains a remarkable $83\%$ of the initial
                      capacity after 1000 cycles even when it is cycled at $100\%$
                      depth of discharge. By contrast, the
                      Li[Ni0.885Co0.1Al0.015]O2 cathode retains only $49\%$ of its
                      initial capacity. The superior cycling stability clearly
                      indicates the importance of the particle microstructure
                      (i.e., particle size, particle shape, and crystallographic
                      orientation) in mitigating the abrupt internal strain caused
                      by phase transitions in the deeply charged state, which
                      occurs in all Ni-rich layered cathodes. Microstructure
                      engineering by surface energy modification, when combined
                      with protective coatings and composition modification, may
                      provide a long-sought method of harnessing the high capacity
                      of Ni-rich layered cathodes without sacrificing the cycling
                      stability.},
