Addressing first cycle irreversible capacity in lithium-rich layered oxides by blending with delithiated active materials.

ABSTRACT: Lithium-rich oxides (LRO), derived from NMC-type materials, are among the most promising next-generation positive electrode candidates for lithium-ion batteries. Despite their potential, their practical application is hinderend by inherently low first-cycle coulombic efficency, caused by the irreversible loss of lithium. In this work, we address this drawback by chemically delithiating secondary active materials - LiMn₂O₄ (LMO) or LiFePO_4- and subsequentyly blending them with the cobalt-free lithium rich oxide Li₁.₁₅Ni₀.₃Mn₀.₅₅O₂. The incorporation of these delithiated components improves not only first-cycle efficiency but also capacity retention, with the degree of enhancement pr
