Gradient‐Integrated High‐Strength and High‐Toughness Cellulose Triboelectric Materials for Enhanced Charge Storage and Transport

Advanced Science, EarlyView.
Inspired by the gradient structure of sea urchin spines, a gradient‐integrated cellulose/multi‐walled carbon nanotube (MWCNT) triboelectric material is constructed. A compatible interface and built‐in electric field synergistically suppress charge dissipation, achieving 20.5 nC cm−2 surface charge density, 8044‐cycle stability, 126.33 MPa tensile ...

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
