Inspired by the cucumber-like structure, by combining the in situ chemical oxidative polymerization with facile soaking process, we designed the heterostructured nanomaterial with PEDOT as the shell and MnO(2) nanoparticles as the protuberance and synthesized the novel cucumber-like MnO(2) nanoparticles enriched vanadium pentoxide/poly(3,4-ethylenedioxythiophene) (PEDOT) coaxial nanowires. This heterostructured nanomaterial exhibits enhanced electrochemical cycling performance with the decreases of capacity fading during 200 cycles from 0.557 to 0.173% over V(2)O(5) nanowires at the current density of 100 mA/g. This method is proven to be an effective technique for improving the electrochemical cycling performance and stability of nanowire electrodes especially at low rate for application in rechargeable lithium batteries.

Electronic and structural dynamics of an industrially relevant Pt/CeO2–ZrO2 catalyst with an ordered arrangement of Ce and Zr ions during oxygen storage/release processes at 573–773 K were studied in real time by time‐resolved energy‐dispersive XAFS at the Zr K edge and Ce L3 edge (see experimental setup). On the basis of these results, the roles of Ce and Zr ions in the function of the mixed‐oxide catalyst were elucidated.

Advanced high‐energy‐density energy storage systems with high safety are desperately demanded to power electric vehicles and smart grids. Li metal batteries (LMBs) can provide a considerable leap in battery energy. Nevertheless, the widespread deployment of Li metal has long been fettered by the unstable solid electrolyte interlayer and uncontrolled Li dendrite growth induced safety concerns. Herein, a flexible and conformal CTF‐LiI coating has been rationally coated on Li metal surface to stabilize metallic Li. With the CTF‐LiI coating, the Li electrodeposition exhibits a uniform, dense, and dendrite‐free manner; however, the side reactions between metallic Li and electrolyte have been effectively suppressed. The Li symmetric cells can run stably for a prolonged cycling over 2500 cycles at 10 mA cm−2, demonstrating a much lower voltage hysteresis. In addition, the Li|Li4Ti5O12 cells can deliver an improved long‐time cycling over 250 cycles at 0.05 A g−1. Furthermore, the half cells paired with the organic S cathode also demonstrate an excellent long lifespan stable cycling and a high capacity of 682.2 mAh g−1 retained over 300 cycles with an average capacity decay of ≈0.05% per cycle at 1.0 A g−1. This work demonstrates a significant step toward large‐scalable and long‐cycling stable LMBs.
