A Quantitative Lithium Inventory Framework for Anode‐Free Lithium Metal Batteries

Advanced Energy Materials, EarlyView.
A component‐resolved lithium inventory framework quantitatively tracks Li redistribution across the cell in anode‐free NMC622||Cu pouch cells throughout cycling. Three sequential degradation stages are identified: formation‐driven cathode Li depletion, midlife inactive Li0 accumulation, and late‐stage runaway SEI thickening. The cathode, as the sole Li

Polymer Electrolyte–Cathode Surface Bonding Suppresses Oxygen Evolution and Cation Mixing in Ni‐Rich Layered Oxides for Lithium Batteries

Small, EarlyView.
Structural stability of NMC is enhanced by introducing strong Ni–Opolymer bonds, such as those in carbonate‐based (PTMC) electrolytes. Strong hybridization between surface Ni and polymer oxygen facilitates oxidation of undercoordinated Ni2+, thereby mitigating Li/Ni mixing and O2 evolution at deep delithiation states.

Unmanned Aerial Systems for Corrosion Detection: Multi‐Sensor Technologies, Challenges, and Opportunities for Next‐Generation Inspection

Quality and Reliability Engineering International, Volume 42, Issue 6, Page 3565-3583, October 2026.
ABSTRACT Corrosion remains a critical threat to the integrity and service life of infrastructure in industries such as oil, gas, construction, renewable energy, and transportation. Traditional inspection methods, being labor‐intensive, hazardous, and often subjective, fall short in addressing modern inspection demands.
