In-situ construction of a thermodynamically stabilized interface on the surface of single crystalline Ni-rich cathode materials via a one-step molten-salt route

Nickel rich LiNi x Co y Mn 1− x − y O 2 cathode materials have been studied extensively to increase the energy density of lithium-ion batteries (LIBs) due to their advantages of high capacity and low cost. However, the anisotropic crystal expansion and contraction inside the secondary particles woul...
