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 utilization of manganese oxides/oxyhydroxides as efficient supercapacitor electrode materials is limited by their cyclic stability. However, the fabrication of manganese oxide/oxyhydroxide nanoparticles embedded in DNA scaffolds has been found to significantly improve their stable electrochemical performance. DNA acts as a strong support material, enhancing the cyclic stability of the electrode materials. This unique approach of utilizing DNA as a stable support material can be used for a wide range of electrochemical applications.

Summary: Large scale recycling of lithium ion batteries (LIBs) is crucial for obtaining raw materials and implementing clean energy strategies. However, efficient and sustainable recycling methods for LIBs are yet to be developed. This study demonstrates a sequential process using two bacterial species to recover manganese, cobalt, and nickel, while keeping lithium in the leachate. The feasibility of manganese recovery from polymetallic solutions was also shown in a 30 L bioreactor. Additionally, proteomic analysis was used to investigate the selectivity between cobalt and nickel, confirming the potential of a bio-based method for separating these metals.

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: The solid-state diffusion coefficient of the electrode active material is an important parameter in lithium-ion battery modeling. This study compares the effectiveness of the galvanostatic intermittent titration technique (GITT) and a faster alternative technique, intermittent current interruption (ICI). The results show that both methods can accurately determine the diffusion coefficient, with the ICI method allowing for more frequent measurements and shorter experiment time. Different fitting approaches and fitting length have minimal impact on the estimation accuracy.

Summary: This study examined the application of foundry sand waste materials in road construction and structural fill from ten different industries. Laboratory tests were conducted to assess the physical, chemical, and geotechnical properties. Stabilization with cement was done for two samples, and the effects of curing period and cement content on key parameters such as compressive and tensile strength were analyzed. It was found that finer samples were suitable for subbase layer construction while both samples could be used as structural fill, supporting sustainable construction practices.

Summary: This article presents a flexible controller algorithm for bidirectional modular cascaded H-bridge (CHB)-based battery storage systems that aims to maintain high-quality power and balanced battery voltages. The algorithm is based on a finite-set model-predictive current control technique and takes advantage of voltage vector redundancy to achieve balancing. The proposed modifications improve computational efficiency and minimize voltage differentials caused by nonideal semiconductors. The approach is efficient, easy to implement, and eliminates the need for additional control loops. Simulations and experiments confirm the feasibility and positive impact of the battery voltage balancing terms in battery storage applications.

Summary: The safety of lithium-ion batteries (LiBs) is crucial for the development of batteries in electric vehicles and energy storage systems. Battery accidents involving fire and explosions have been reported, mainly due to thermal runaway (TR) caused by operating LiBs outside their normal range. This paper reviews the safety testing of LiBs, including temperature effects, abuse testing scenarios, and international battery standards. Overcharging and thermal abuse testing are the most documented and observed causes of battery safety accidents. Improvements in safety testing, particularly for internal short-circuits, are needed to reduce the TR hazard in LiB applications.
