Abstract
The invention provides a battery material comprising-monocrystalline particles not having internal void fractions, wherein each of the monocrystalline particles is without internal grain boundaries such that anisotropic volume change issues of polycrystalline particles don't occur when the particles are charged and discharged during cycling. Also provided is the monocrystalline particles with less-lithium on the particle surface. Also provided is a method for preparing monocrystalline battery material, wherein the battery material may be incorporated into a secondary battery.
