Synergistic Microstructure and Dielectric Engineering of Recyclable Single‐Electrode Triboelectric Nanogenerators for Sustainable Smart Homes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A recyclable triboelectric nanogenerator integrating a pseudo‐honeycomb microstructure with liquid metal doping achieves 120% higher output (122 mW m−2) and >90% retention over seven cycles, enabling self‐powered smart home functions. The performance of single‐electrode triboelectric nanogenerators (SE‐TENGs) is governed by the effective contact area ...

A High‐Performance Oxidized Graphene for Dendrite‐Free Anodes and Kinetically Enhanced Cathodes of Aqueous Zn‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Oxidized graphene rich in carboxylic acid groups obtained via a simple electrochemical exfoliation route is shown to tackle the main challenges of aqueous Zn‐ion batteries (AZIBs), specifically short Zn anode cycle life and sluggish cathode reaction kinetics.

Finite Element Analysis for Li Batteries at the Mesoscale

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Finite element analysis (FEA), through multi‐physics coupling, has been widely employed to calculate mesoscale structures in LIBs that exhibit inherent randomness and disorder (Figure a). It has been extensively applied to the investigation of critical phenomena such as Li dendrite evolution, Li+ concentration gradients, SEI film growth, particle ...

Unlocking the Role of Carbon Microstructure in MOF‐Mediated Interfacial Engineering for Fast‐Charging Sodium‐Ion Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work compares sodium storage behaviors of Zn‐MOF modified different carbon matric. On cellulose‐derived hard carbon, Zn‐MOF induces interfacial reconstruction with enhanced conductivity and abundant iontransport channels for fast Na+ migration. The performance of hard carbon anodes in sodium‐ion batteries is restricted by the inherent trade‐off ...
