Summary: The proposed method for lithium plating detection in lithium-ion batteries utilizes the DEIS technique and can effectively detect lithium plating in real-time during the charging process. By analyzing the impedance of the battery in the frequency domain, the method is capable of detecting lithium plating by monitoring the real and imaginary parts of the battery impedance. The experimental results show that the DEIS technique is effective for detecting lithium plating at different temperatures and charging conditions, for rates as high as 6C, and for different battery types.

Summary: The design of optimized charging strategies based on electrochemical models is crucial for the broader use of electric vehicles. Lithium plating on the anode surface, which is closely related to charging lifetime and battery safety, should not be ignored in charging strategy design. By using electrochemical models in combination with the lithium plating criterion, the maximum charging current that prevents lithium plating can be identified, facilitating accurate determination of model parameters. However, most current studies have not considered the influence of electrochemical parameters on characterizing variables for the lithium plating criterion. To improve the accuracy of the electrochemical model for the lithium plating reaction, a sensitivity analysis of different parameters was carried out, and the effect of temperature was also investigated.

Summary: This work investigates the influence of low temperatures and current rates on lithium (Li) plating in lithium-ion batteries (LIBs) through electrochemical tests, material characterization, and numerical analysis. The results show that at lower temperatures and higher current rates, the battery charging process shifts from normal intercalation to Li plating, which eventually leads to failure. The morphology observations reveal the growth process of Li plating, and quantitative analysis reveals the dynamic pattern under long-term cycles. The study provides detailed information on the range and growth process of Li plating, which can be used for practical prediction and regulation.

Summary: This paper introduces the application of the distribution of relaxation times method (DRT) in lithium-ion battery research. It points out that the current focus is mainly on the mid-high frequency range, while processes in the low frequency area, such as diffusion, have received less attention. The difficulties of applying the DRT method to diffusion processes are discussed, along with the limitations of the galvanostatic intermittent titration technique (GITT). By developing a comprehensive theory and an analytical expression, the paper provides a way to determine the solid phase diffusion coefficient with a firm physico-chemical background. Experimental verification is conducted on specific materials. Comparisons with GITT measurements reveal that GITT fails to exclude the influence of liquid diffusion, leading to underestimated solid diffusion coefficients.

Summary: Ni-rich ternary layered oxide materials are preferred cathode materials for lithium-ion batteries due to their high specific discharge capacity and low cost. However, the hierarchical structure of these materials suffers from structural collapse, resulting in serious side reactions and capacity decline, especially at high cut-off voltage. Single-crystalline materials and surface modification with nano-TiO2 can improve the cycling performance by inhibiting intergranular cracking and side reactions at the electrode/electrolyte interface.

Summary: In this study, the influence of TiAl gate electrodes fabricated by physical vapor deposition (PVD) and atomic layer deposition (ALD) on electron mobility in metal-gated NMOSFETs was investigated. The ALD TiAl film contained a high amount of C atoms which suppressed its O-gettering capability. The PVD TiAl device showed about 15% higher peak mobility compared to the ALD TiAl device, attributed to lower bulk trap density in gate dielectric layers and the ability to extract more O atoms.

Summary: In this work, the variation of threshold voltage (V-t) for multi-V-t FinFETs is investigated by changing the thickness of work function metal (WFM) TiN from the perspective of process integration. Four different WFM thicknesses are prepared through a combination of atomic layer deposition (ALD) and wet etching of TiN layers. The results show that the V-t variation is significant for N-FinFET with only one layer of TiN, and the TiN layer is partially eroded during wet etching, even though it should be protected by a photoresist. It is proposed and demonstrated that a high-temperature pre-baking treatment can effectively reduce the unexpected erosion of the TiN layer and suppress the V-t variation.

Summary: Lithium-oxygen batteries have high energy density, but conventional liquid electrolytes struggle to form a stable solid electrolyte interface (SEI) on the cathode surface for long-term stable cycling. LiBOB is added to the LiTFSI-based electrolyte to solve this issue. The introduction of LiBOB induces the dissociation equilibrium of the lithium salt positively, resulting in an electrolyte with good ionic conductivity. Different amounts of LiBOB exhibit different characteristics in electrochemical performance, with trace amounts improving discharge capacity. The synergistic effect of the LiTFSI-LiBOB dual-salt electrolyte forms a protective SEI, leading to comparable cycling performance.

Summary: This paper investigates the preparation method of solid-state electrolytes (SSEs) for lithium metal batteries with different solvent contents. The presence of residual solvent in SSEs can affect their performance. The study reveals that the solvent content decreases with drying time, but even after 48 hours of vacuum drying, it still contains more than 5% solvent. The presence of residual solvent promotes the binding of lithium ions and carbonyls, facilitating the transfer of lithium ions. When the solvent content is high, SSEs exhibit high ionic conductivity, cycling capacity, and excellent cycling stability, while decreasing solvent content widens the electrochemical window.

Summary: This study reveals that the OFF-state leakage of short channel n-FinFETs can be significantly reduced by the self-adaptive etching of work function metal TiN. The microloading effect is utilized to achieve the self-adaptive etching, resulting in a thick TiN layer with a high work function on the fin bottom and a thin TiN layer with a low work function on the fin top for short channel n-FinFETs. Such nonuniform work function distribution effectively reduces the threshold voltage roll-off.

Summary: Increasing the Ti-silicidation anneal temperature can lower the threshold voltage (Vt) for FinFET with TiAl based metal gate. It is found that the reduction in Vt is related to the deoxidation of Ti, segregation of O, and oxidation of Al in the TiN/TiAl/TiN/TaN stack. A new effective work function (EWF) tuning model is proposed, which suggests that the EWF is determined by the formation of metallic Ti or TiC in the C-rich TiAl layer and the formation of metallic Ti in the C-free TiN layer.

Summary: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

Summary: By coupling electrochemical testing to operando synchrotron based X-ray absorption and powder diffraction experiments, blended positive electrodes consisting of LiMn2O4 spinel (LMO) and layered LiNi0.5Mn0.3Co0.2O2 (NMC) were studied to understand their redox mechanism. It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
