Nickel-rich layered oxides are promising positive electrode materials for lithium-ion batteries due to their high capacity and decreased cobalt content. The application of surface coatings is a common approach to slowing or potentially stopping delet

The solid electrolyte interphase (SEI) that forms on Li-ion battery anodes is critical to their long-term performance, however observing SEI formation processes at the buried electrode-electrolyte interface is a significant challenge. Here we show th

Understanding how lithium-ion dynamics affect the (de)lithiation mechanisms of state-of-the-art nickel-rich layered oxide cathodes is crucial to improving electrochemical performance. Here, we directly observe two distinct kinetically-induced lithium

Activation of oxygen redox represents a promising strategy to enhance the energy density of positive electrode materials in both lithium and sodium‐ion batteries. However, the large voltage hysteresis associated with oxidation of oxygen anions duri

Although layered lithium nickel-rich oxides have become the state-of-the-art cathode materials for lithium-ion batteries in EV applications, they can suffer from rapid performance failure – particularly when operated under conditions of stress (tem

17O NMR is an invaluable tool to study the structure and dynamics of oxide materials, but remains challenging to apply in many systems. Even with isotopic enrichment, studies of samples with low masses and/or concentrations of the active species, suc

Li-O2 batteries (LOBs) operating via LiOH chemistry have attracted increasing interest due to the higher stability of LiOH in organic electrolytes, compared to Li2O2. Several catalysts have been shown to promote the formation of LiOH during discharge

LiI-promoted LiOH formation in Li-O2 batteries with wet ether electrolytes has been investigated by Raman, nuclear magnetic resonance spectroscopy, operando pressure tests and molecular dynamics simulations. We find that LiOH formation is a synergist

Titanium doping in lithium manganese oxide spinels was shown to be beneficial for the structural stability of the potential Li-ion battery cathode materials LiTi x Mn 2−x O 4 , 0.2 ≤ x ≤ 1.5, yet the distribution of Li/Ti/Mn in the structure an
