Hollow‐Structured Li Hosts Featuring Lithiophilic Metal/Metal Compound Sites for Li‐Metal Anodes

Advanced Science
ABSTRACT Li‐metal anodes (LMAs) have attracted significant interest in high‐energy‐density Li‐metal batteries (LMBs) due to their high theoretical capacity and low electrochemical potential. Nonetheless, the instability and host‐less nature of Li impede the development of stable LMBs.

Impact of the Process Atmosphere During Hot Isostatic Pressing on the Near‐Surface Composition of an Additively Manufactured Austenitic High‐Interstitial Steel

Advanced Engineering Materials, EarlyView.
A high interstital austenitic steel is additively manufactured and postdensified by HIP to eliminate gas porosity. Thereby, the loss of N and Mn in Ar HIP atmosphere is investigated. Further, HIP using N2 atmosphere is investigated which led to excessive nitride formation.

A Multi‐Scale Machine Learning Framework for the Inverse Design of High Entropy Alloys

Advanced Engineering Materials, EarlyView.
High‐entropy alloys offer vast potential for various applications, including electrocatalysis; however, their compositional complexity challenges conventional screening. We introduce an inverse‐design framework combining two neural networks to determine optimal compositions and reconstruct nanoparticle geometry from targeted properties and conventional

Plasma-activated tight and uniform grown of metal-organic frame-work on carbon cloth for stable Li metal anode [PDF]

The significant expansion in volume and the formation of dendrites on lithium metal anodes lead to poor electrochemical reversi-bility. In this study, ZnO, N-dually doped carbon (p-ZNCC) was synthesized using oxygen plasma assistance and zeolitic imidazo-

Facile One-Step Heat Treatment of Cu Foil for Stable Anode-Free Li Metal Batteries

, 2023
The anode-free lithium metal battery (AFLMB) is attractive for its ultimate high energy density. However, the poor cycling lifespan caused by the unstable anode interphase and the continuous Li consumption severely limits its practical application. Here,

Methods to Improve Lithium Metal Anode for Li-S Batteries [PDF]

Frontiers in Chemistry, 2019
The lithium-sulfur (Li-S) battery has received a lot of attention because it is characterized by high theoretical energy density (2,600 Wh/kg) and low cost. Though many works on the "shuttle effect" of polysulfide have been investigated, lithium metal anode is a more challenging problem, which leads to a short life, low coulombic efficiency, and safety

Strategy to Enhance the Cycling Stability of the Metallic Lithium Anode in Li-Metal Batteries

Nano Letters, 2021
Based on the analysis of systematic research (density functional theory calculations, physical characterizations, and electrochemical performances), here, we report a novel mixture surface modification layer of LiC6&LiF, which can enhance the lithium-ion diffusion and decrease the local current density.

Detecting Anomalous Cell Behavior in Electrochemical Battery Testing Using Machine Learning

Advanced Engineering Materials, EarlyView.
Machine‐learning‐based screening enables automated identification of anomalous battery cells from complementary electrochemical tests. A curated battery database supports configuration‐aware comparison of rate‐capability and impedance data. Supervised classification of rate‐test data achieves 90% accuracy, while CNN‐VAE‐based impedance analysis reaches

Electrodeposition in Structural Lattices of Variable Architectures

Advanced Engineering Materials, EarlyView.
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.
