a) TOF‐SIMS characterization of the LRLO cathode electrodes before and after high‐temperature storage. Normalized depth profiles of the interface and bulk fragments illustrate the structure of the CEI. b) 3D renderings of selected secondary ion fragments of the LRLO cathode electrodes before and after high‐temperature storage. The sputtered volume is 100 µm (length) × 100 µm (width) × 150 nm (height). c,d) The TEM and IFFT images of LRLO cathode before and after high‐temperature storage. e) Scheme of CEI formation and revolution on the LRLO cathode electrodes before and after high‐temperature storage.

In addressing the global climate crisis, the energy storage performance of Li‐ion batteries (LIBs) under extreme conditions, particularly for high‐energy‐density Li‐rich layered oxide (LRLO) cathode, is of the essence. Despite numerous researches into the mechanisms and optimization of LRLO cathodes under ideal moderate environment, there is a dear...

Proton batteries are strong contender for next‐generation energy storage due to their high safety and rapid response. However, the narrow electrochemical window of acidic aqueous electrolytes limits their energy density and stability. Here, an ionic liquid (IL)‐based electrolyte (EMImOTf‐H3PO4) containing H3PO4 in polar IL solvent 1‐ethyl‐3‐methyli...
