Effect of Propagating Dopant Reactivity on Lattice Oxygen Loss in LLZO Solid Electrolyte Contacted with Lithium Metal

open access: yesAdvanced Energy Materials, EarlyView.
The decomposition of Nb‐substituted LLZO solid electrolytes is reported through a propagating reaction between Nb5+ dopants and the Li metal electrode. This work suggests dopants that segregate to interfaces/grain boundaries in LLZO will exhibit reactivity that can propagate into bulk and shed light on new mechanisms for the problematic role of oxygen ...

Ultra‐High‐Capacity of Earth‐Abundant Cathodes Enabled by Excess Fluoride‐Ion Insertion/Extraction

open access: yesAdvanced Energy Materials, EarlyView.
A perovskite oxyfluoride SrFeO2Fx can accomodate excess F– beyond x = 1 in the structure with oxygen redox (O–O bond formation). The Sr‐substituted CaFeO2Fx (Ca0.8Sr0.2FeO2Fx) provides an extremely large capacity of 580 mAh g−1 (2595 mAh cm−3). This research will provide new design principles for the development of all‐solid‐state fluoride‐ion battery ...

13C‐Labeled Mesoporous N‐Doped Carbon Nanospheres and N‐Doped Hydrothermal Carbon Aerogels as Model Materials for Carbon Corrosion Determination in Electrode Structures

open access: yesAdvanced Energy Materials, EarlyView.
By 13C labeling of carbon support materials used in energy storage and conversion applications, carbon corrosion can be investigated in situ via EC‐MS, giving information about the corrosion rate and whether the carbon support or other carbon‐containing materials in the system are degraded.
