Structural Changes and Reversibility Upon Deintercalation of Li from LiCoPO 4 Derivatives

In an effort to improve the cycle life and rate capability of olivine LiCoPO 4 , Cr, Fe, and Si were added to produce nominal Li 1.025 Co 0.84 Fe 0.10 Cr 0.05 Si 0.01 (PO 4 ) 1.025 . This cathode material has an energy density comparable to LiCoPO 4 , with markedly improved electrochemical performance. Here, we apply operando X-ray diffraction to gain an understanding of the crystallographic delithiation mechanism of this new substituted electrode material, compared to both LiCo 0.75 Fe 0.25 PO 4 and LiCo 0.75 Fe 0.25 PO 4 . Throughout charging, the extent of solid-solution domains was significantly increased in Li 1.025 Co 0.84 Fe 0.10 Cr 0.05 Si 0.01 (PO 4 ) 1.025 and LiCo 0.75 Fe 0.25 PO 4 compared to LiCoPO 4 . These domains reduce the mechanical strain during electrode function, providing a clear explanation for the high durability with Co substitution. Li 1.025 Co 0.84 Fe 0.10 Cr 0.05 Si 0.01 (PO 4 ) 1.025 operated at notably higher average potential than LiCo 0.75 Fe 0.25 PO 4 , which would increase the energy density of the cell. Ex situ measurements reveal the persistence of structural irreversibilities in the substituted phase after the first cycle, identifying avenues for further improvement in durability. Overall, this finding sheds light on the strategies for judicious cation substitution in LiCoPO 4 electrodes to maximize the cycle life while preserving high energy density, especially compared to LiFePO 4 .

LT-LiNi 1/3 Mn 1/3 Co 1/3 O 2 : A Partially-Disordered, Composite Rock Salt Cathode Prepared by Flame Spray Pyrolysis for Li-Ion Batteries

A unique composite cathode structure for Li-ion batteries, designated LT-LiNi 1/3 Mn 1/3 Co 1/3 O 2 (or LT-NMC111), has been prepared by flame spray pyrolysis and subsequent annealing between 400 and 650 °C. It is composed predominantly of structurally-integrated and partially-disordered lithiated-spinel and layered components, both of which can be broadly described as partially-disordered rock salt constituents. The paper describes the evolution of the LT-NMC111 structure as a function of the synthesis method, annealing temperature, and electrochemical properties in the context of other recently reported “low-temperature” (LT) materials, such as LT-LiCo 1−x Al x O 2 and LT-LiMn 0.5 Ni 0.5 O 2 or, in spinel notation, LT-Li 2 Co 2–2x Al 2x O 4 and LT-Li 2 MnNiO 4 , respectively.
