Summary: The chemical diffusion coefficient (D) is an important indicator for the diffusion kinetics of ions in electrode materials. However, there are flaws in the conventional tool, galvanostatic intermittent titration technique (GITT), used to test the D value, such as improper model usage and selection of parameters leading to significant differences in results. To improve accuracy, we have formulated standards and analyzed assumptions under different conditions. In addition, we have integrated special measures and new methods derived from GITT to enhance the test results.

Summary: Graphite is commonly used as an anode material in commercial lithium-ion batteries due to its reversible lithium-ion storage capability and low electrode potential. However, the sluggish diffusion kinetics of graphite anodes limit the rate capability of lithium-ion batteries. The diffusion coefficient of lithium ions in commercial graphite anodes can be determined using a galvanostatic intermittent titration technique, revealing mixed phases during lithium intercalation/deintercalation.

Summary: This work presents a parameter identification method using GITT to create high resolution lookup tables and response surfaces for ECM. The method proposes improvements such as open-circuit voltage change compensation and ohmic resistance correction, leading to better accuracy. An iterative parameter identification algorithm is introduced for higher order ECM. The method has been applied to identify parameters of 1RC and 2RC ECM and has shown higher fidelity compared to previous pulse identification methods. The results of experiments on Nickel-Manganese-Cobalt cathode lithium-ion cells demonstrate the high accuracy of the proposed method.

Summary: The lithium-sulfur battery, a promising post lithium-ion battery technology, has attracted attention for its high specific capacity and low price. However, its commercialization progress is slow due to low performance, capacity fading, and low coulombic efficiency. In this study, a mathematical model is developed to describe the complex mechanisms of precipitation and dissolution of individual polysulfide chains. The model is validated by experimental measurements on a prototype lithium-sulfur pouch cell.

Summary: The galvanostatic intermittent titration technique (GITT) is commonly used to evaluate solid-state diffusion coefficients in electrochemical systems, but existing analysis methods have limitations in validating the derived diffusion coefficients. Researchers employed a direct-pulse fitting method to interpret GITT data and found that non-ideal diffusion coefficients were significantly more accurate than ideal ones extracted using conventional methods. This study also demonstrated the validity of a single-particle approach when the modeled radius is proportional to the total volume-to-surface-area ratio of the system.

Summary: The diffusion coefficient and exchange current density are key parameters that determine the electrochemical characteristics of an electrochemical battery model. This study measured these parameters for a LiNi0.4Mn0.3Co0.3O2/Li cell using four different electrochemical methods and applied them to the electrochemical model. The results show that the model using the parameters measured by different methods can accurately simulate the voltage-capacity profiles.

Summary: The passivation of carbon in lithium-sulfur batteries under lean electrolyte conditions does not severely limit performance. Introducing higher surface area carbon in the sulfur electrode formulation is unnecessary to prevent passivation. The focus of lithium-sulfur development should be directed towards addressing other issues such as undesirable reactions at the lithium electrode and achieving robust sulfur electrode structures.

Summary: This study investigates the mechanism of electrolyte decomposition in lithium-ion batteries. The results indicate that the electrolyte decomposition on NMC electrodes can proceed through two distinct routes with different onset potentials. The consumption of water at the negative electrode can effectively reduce the decomposition products, thereby mitigating the degradation of NMC/graphite cells.

Summary: In this study, the nucleation and growth of Li clusters on the graphite anode in Li-ion batteries were investigated using theoretical calculations. The results showed that the growth of clusters is influenced by the applied voltage and the lithiation level of the graphite. The zigzag edge termination and lithiated graphite were found to be more prone to nucleation and growth. Additionally, the surrounding electrolyte environment plays a significant role in the nucleation process.
