Designing Surface Coating Strategies with Tungsten on Single Crystal NMC Materials by XPS

open access: yesAdvanced Energy Materials, EarlyView.
The compounds Li2WO4 and Li4NiWO6 are identified on the surface of tungsten‐coated single crystal NMC cathode materials. It is shown that Li4NiWO6 is preferred for materials with the best performance. Synthesis routes to obtain materials with either surface species are presented.

Analyses of Electrode–Electrolyte Interactions in Commercial Layered Oxide/Hard Carbon Na‐Ion Cells via Optical Sensors

open access: yesAdvanced Energy Materials, EarlyView.
Use of advanced optical sensing techniques to track operando the physical and chemical changes of interfacial reactions in commercial type sodium‐ion cells. The nature of layered oxide cathode (O3 vs P2) influences the electrolyte reactivity and additives reduce the parasitic reactions.

Growth of Omnichannel Grocery Retailing and Food Prices

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper examines the effects of the growth of omnichannel grocery retailing on food prices. We first develop a conceptual model of consumer choice and retailer pricing that allows us to evaluate changes in equilibrium prices, quantities, and profits with online channel growth and alternative pricing strategies.

Interfacial Modification of High‐Voltage LiCoO2 Materials via Ti/Mg Doping Strategy for Inhibiting Harmful Phase Transition Effect

open access: yesAggregate, EarlyView.
Ti/Mg doping strategy for inhibiting harmful phase transition effect of LiCoO2 materials has been developed. The coating of Li3TiMg(PO4)3 can stabilize the surface crystal structure and boost the mechanical stability of LiCoO2 materials. The modified LiCoO2 materials shows a discharge specific capacity of 115.9 mAh·g−1 at 5 C, demonstrating outstanding
