Stabilizing Oxygen Redox in Polycrystalline Li-Rich Layered Cathodes via Efficient Grain Boundary Passivation.
High-voltage cathodes with hybrid anion and cation redox activities, such as Li-rich and Mn-rich oxides, offer a pathway to higher energy density in lithium-ion batteries (LIBs). However, those cathodes suffer from oxygen loss from both the surface and grain boundaries, especially in traditional polycrystalline cathode...
