Adaptive Backstepping Control for Battery Pole Strip Mill Systems with Friction and Dead-Zone Input Nonlinearities

Actuators
The dead-zone input and hydraulic cylinder friction of the pump-controlled automatic gauge control (AGC) system introduce significant challenges to the high-precision rolling of lithium battery pole pieces.

Amelioration of Ultrasonic Transducer to Study CuO Doped Thin Films

Archives of Acoustics, 2018
Ultrasonic pulse echo technique was used to study cupric oxide (CuO) thin films. CuO thin films were prepared using sol gel technique. They were doped with Lithium (Li) (1%, 2% and 4%). Thin films’ thickness (d) and band gap energy (Eg) were measured.

XTRUDE: A Process‐Informed Framework for High‐Fidelity Analysis of Hydrogel Extrusion

Advanced Functional Materials, EarlyView.
Extrusion performance emerges from the interplay between material properties and processing conditions. XTRUDE (eXTrusion Rheology for Understanding and Defining Extrudability) recreates the extrusion environment with in situ pressure and temperature sensing, enabling characteristic pressure signatures to quantify extrusion‐specific phenomena and ...

Engineering a Fluorinated AlPO4 Interface: Toward High Initial Coulombic Efficiency and Stable Oxygen Redox in Li‐Rich Layered Oxide Cathodes

Advanced Functional Materials, EarlyView.
We report a chemically incorporated fluorinated AlPO4 (AlPO4‐F) architecture that functions as a multifunctional “interfacial fortress” for Li‐rich layered oxides (LLOs). By modulating the surface potential to –32.16 mV, this architecture enriches Li+ concentration and repels detrimental electrolyte anions.

Manipulating the diffusion energy barrier at the lithium metal electrolyte interface for dendrite-free long-life batteries

Nature Communications
Constructing an artificial solid electrolyte interphase (SEI) on lithium metal electrodes is a promising approach to address the rampant growth of dangerous lithium morphologies (dendritic and dead Li0) and low Coulombic efficiency that plague ...

Engineering 3D copper foam current collectors: modification strategies and challenges toward stable lithium metal batteries

Science and Technology of Advanced Materials
Lithium metal is a promising anode for high-energy batteries due to its high capacity and low density. However, issues like dendrite growth and volume expansion limit its practical use.

Reaction‐Time pH Stabilization by Poly(acrylic acid) with Ethanol‐Mediated Growth Control for Efficient Hydrothermal Sb2(S,Se)3 Solar Cells

Advanced Functional Materials, EarlyView.
Poly(acrylic acid) acts as a reaction‐time pH buffer during hydrothermal Sb2(S,Se)3 growth through its COOH/COO‐ equilibrium. When combined with ethanol‐regulated growth, this buffering strategy reduces Sb‐O related surface disorder, improves local electronic uniformity and carrier collection, and increases the champion solar‐cell efficiency to 10.25%,

In situ evaluation and manipulation of lithium plating morphology enabling safe and long‐life lithium‐ion batteries

InfoMat
The morphology of plated lithium (MPL) metal on graphite anodes, traditionally described as “moss‐like” and “dendrite‐like”, exert a substantial negative influence on the performance of lithium‐ion batteries (LIBs) by modulating the metal‐electrolyte ...

Role of Structural Disorder on Phonon Transport and Thermal Conductivity in Li6PS5Br

Advanced Functional Materials, EarlyView.
Solid electrolytes are fast ion and slow heat conductors. Although both transport properties are governed by lattice dynamics and atomic structure, their interplay remains poorly understood. Here, we study this interrelation in anion‐ordered and disordered Li6PS5Br.
