ABSTRACT

ABSTRACT

Lithium-rich Li(1.13)Ni(0.30)Mn(0.57)O2 has been functionally modified with fast Li(+)-ion conducting Li2SiO3via a facile and novel method, based on the reaction between Ni(0.35)Mn(0.65)C2O4·xH2O and Si(OC2H5)4. Due to the unique Li2SiO3 coating layer which greatly improves the Li(+) ion diffusion rate, Li2SiO3@Li(1.13)Ni(0.30)Mn(0.57)O2 exhibits outstanding rate capability, cycle stability and low polarization.
