Enhancing the Storage Performance and Thermal Stability of Ni-Rich Layered Cathodes by Introducing Li₂MnO₃

Energies
Ni-rich layered cathodes are deemed as a potential candidate for high-energy-density lithium-ion batteries, but their high sensitivity to air during storage and poor thermal stability are a vital challenge for large-scale applications.
