Summary: Flexible solid-state battery with high flexibility, easy portability, and high safety shows great potential in new technology products. However, the mechanical and electrochemical problems caused by bending deformation are worth exploring. This study develops a fully coupled electro-chemo-mechanical model to investigate the influence of different bending forms on the battery's performance. The results suggest that the negative curvature bending reduces plastic strain but causes capacity loss due to negative potential shift.

Summary: The study presents a thermodynamically-consistent electro-chemo-mechanical gradient theory that couples electrochemical reactions with mechanical deformation and damage in solids. The framework models species transport and electrochemical reactions within the solid host, with electrodeposition impacting mechanical deformation and stress generation, and vice versa. The theory specializes in simulating Li-metal filament growth phenomena in a Li-metal-Li7La3Zr2O12 (LLZO) system, capturing both intergranular and transgranular crack and Li-filament growth mechanisms observed experimentally. The theory has broad engineering applications where electrochemical reactions occur within damage zones, leading to deposition of new material at these locations.

Summary: Graphite is the dominant anode material for lithium-ion batteries, but it is prone to Li-plating when charged fast or at low temperatures, resulting in performance degradation and safety concerns. This study clarifies the mechanism of lithium evolution from graphite particles and reveals that the degradation of graphite anode is accelerated by the decrease of Li-plating overpotential. This finding contradicts the popular theory and provides insight for the design of advanced materials and electrodes to avoid Li-plating and achieve fast and safe charging.

Summary: The study reveals that amorphous Si anodes can withstand higher hydrostatic stress, while prone to mechanical failure under biaxial or uniaxial stress. The thermodynamic stability of a-Si anodes is mainly influenced by external mean stresses, with compressive stress destabilizing the anodes and causing capacity fading. Previous continuum models underestimate the open-cell potentials of a-Si anodes due to neglected volumetric deformation at higher stresses and Li concentrations.

Summary: This study optimized an in situ method for measuring the mechanical behavior and properties of silicon-based electrodes during electrochemical cycling. The research found that the swell strain and partial molar volume of Si electrodes increase with the Li concentration, while the elastic modulus generally decreases. The in-plain stress transforms from tensile stress to compressive stress during lithiation and shows an increasing tendency, but reverses during delithiation. These findings provide input parameters for battery modeling and help understand capacity fading of Si electrodes.

Summary: The Point Defect Model (PDM) has been used to understand passivity for over 40 years. However, the model is based on unconfirmed assumptions. To address this limitation, a Refined PDM (R-PDM) is proposed, which includes additional equations and boundary conditions to account for finite dimensions of defects. The calculations using R-PDM show that the original assumptions of PDM are only valid for specific parameter combinations and cannot be generally assumed. These findings contribute to a more realistic description of passive layer formation.
