Unveiling Bubble Dynamics of Proton Exchange Membrane Water Electrolysis at Elevated Temperatures

open access: yesEcoEnergy, EarlyView.
This work directly visualizes bubble dynamics in a proton‐exchange membrane water electrolyzer operated at temperatures up to 120°C and pressures up to 100 bar. Elevated‐temperature operation beyond the atmospheric boiling point markedly reduces bubble coverage, leading to lower bubble‐related voltage losses and enhancing cell performance.

One‐Pot Spray Pyrolysis Fabrication of Multi‐Phase Lithium Manganese Oxide Microsphere Cathodes for Enhanced Lithium‐Ion Battery Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Sr‐LMO microspheres were synthesized by one‐pot spray pyrolysis, forming multi‐phase lithium manganese oxide with Sr‐doped LiMn2O4, Sr2Mn2O5, and Li2MnO3‐like domains. This structure refines particles, suppresses Jahn–Teller distortion, and adds Li+ pathways, delivering superior cycling stability and rate performance over undoped and commercial LMO ...

Redistributing Cobalt and Tungsten From WC–Co Soft Scrap Toward Sustainable Cathode and Coating Materials for Lithium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sustainable upcycling strategy transforms tungsten carbide–cobalt (WC–Co) soft scrap into high‐performance cathode materials. Recycled Co with trace nickel (Ni) is resynthesized into stabilized LiCoO2 with superior high‐voltage durability, while the recovered tungsten is further utilized as tungsten trioxide to enhance Ni‐rich cathode interfaces ...
