Advanced Materials, EarlyView.A green, external‐catalyst‐free route grows defect‐free covalent organic framework membranes directly on ion‐exchange supports using an alternating electric field and in situ‐generated acid. Through a self‐regulating, self‐healing mechanism, the membranes achieve near‐complete, ultra‐fast separation of monovalent ions such as Li+, Na+, and K+, offering

Lithium-ion conducting ceramic/polyether composites
, 1998 Composites of a lithium ion conducting ceramic with a lithium salt based polymer electrolyte matrix are described. Conductivity measurements as a function of the lithium ion conducting ceramic phase content in the composite show that there is a ...

Advanced Materials, EarlyView.Interfacial reactions in all‐solid‐state batteries are conventionally suppressed; here, they are designed. Vacancy‐rich β‐Li3N, acting as an anolyte, reacts controllably with silicon during composite anode fabrication, building a purpose‐made lithium nitridosilicate interlayer on every particle surface.

Progress on the Attenuation Mechanism and Modification of the Cobalt‐Free Spinel LiNi0.5Mn1.5O4
Advanced ScienceCobalt‐free LiNi0.5Mn1.5O4 (LNMO) has recently emerged as a highly promising cathode material owing to its benefits of a high operating voltage platform (≈4.7 V vs Li), high theoretical energy density (≈650 Wh kg−1), eco‐friendliness, and resource ...

Probing the Causes and Effects of Parasitic Reactions in Lithium-Ion Cells
, 2018 Parasitic reactions in lithium-ion cells consume solvent, salt and active lithium ions, resulting in a loss of capacity and eventual cell failure. The projects described in this thesis have the common goal of exposing the chemical mechanisms of these ...

Lithium-Rich Transition Metal Oxides as Positive Electrode Materials in Lithium-Ion Batteries
, 2010 Lithium-rich transition metal oxides are candidates for the next-generation lithium-ion battery positive electrode materials. They have a much higher first charge and low-rate cycling capacity compared to non-lithium rich transition metal oxides.

Advanced Materials Interfaces, EarlyView.Volume changes of a solid‐state battery cell are separated into the individual contributions of anode and cathode. Simultaneously determining the “reaction volumes” of both electrodes requires a reference electrode with a pressure‐independent potential.
