Summary: Differentiation of a Li-ion battery cycling profile results in a pair of complementary measures, differential capacity and differential voltage, which are used to diagnose cell state and aging mechanisms. This article presents a fundamental theory of differential analysis from single electrode measurements to full cell data, considering cell balancing and degradation. The new approach uses a graphical heuristic to superimpose voltage and capacity data on a 2D representation of the cell state, harmonizing various complementary approaches from existing literature.

Summary: Graphene is a promising electrode material for electrical double-layer capacitors, but the dominant hydrogen evolution reaction (HER) in the negative voltage window limits the energy density. Introducing a co-solvent electrolyte of dimethyl sulfoxide (DMSO) in water has been shown to suppress HER, but the role of DMSO in expanding the negative voltage window needs further explanation. Using molecular dynamics simulations, we found that DMSO replaces part of water molecules on the electrode surface, leading to a passivation layer that reduces HER activity. The amount of Na center dot H2O, which exhibits high HER activity, is related to the operating negative voltage window. Our work provides new insights into the mechanism of co-solvent electrolyte in expanding the negative voltage window.

Summary: This study proposes a strategy to enhance the high-voltage stability of medium-concentration ether electrolytes by altering the reaction pathway of ether solvents. By employing a 1 M lithium difluoro(oxalato)borate in dimethoxyethane (LiDFOB/DME) electrolyte, a stable organic-inorganic hybrid interface is formed, leading to improved cycling performance in lithium metal batteries. The optimized ether electrolyte demonstrates outstanding cycling performance in practical conditions.

Summary: Predicting the lifetime of lithium-ion batteries is crucial for the widespread use of electric vehicles, aviation, and the grid. The growth of solid-electrolyte interfaces (SEI) is considered the main degradation mechanism for batteries. This study reveals a negative feedback loop between loss of active material (LAM) and SEI growth due to reduced solvent concentration, which slows down SEI growth. It also suggests that adding extra electrolyte at the beginning can greatly improve the battery's service life.

Summary: Increasing the energy density of energy storage devices is a key target for battery and supercapacitor research. This article focuses on the electrochemical stability window (ESW), which determines the effective energy density of the devices. The concentration of the electrolyte affects the ESW by altering the HOMO/LUMO levels and modifying the physicochemical properties of the electrolyte. The article discusses the mechanisms behind the extension of the ESW and the improved rate capabilities and stability in batteries and supercapacitors achieved through high salt concentrations.

Summary: This study reveals the influence mechanism of transition metal deposition on the performance of lithium-ion batteries through proposing a comprehensive capacity degradation model. Experimental results show that Li plating significantly reduces the lithium-ion concentration, leading to capacity attenuation; while the growth of SEI alone has little effect on the capacity, and Mn dissolution accelerates SEI layer growth, significantly affecting battery capacity.

The introduction of bimetallic components enhances the electronic/ionic conductivity and optimizes the redox dynamics, resulting in superior electrochemical performance. The AIPSe@G anodes achieve high specific capacity, excellent cycle stability, and rate capability in both lithium-ion (LIBs) and potassium-ion batteries (PIBs). The comprehensive full cell tests further demonstrate the stability of AIPSe@G anodes under diverse current regimes.

Summary: In the context of increasing global environmental pollution and constant increase of carbon emission, hydrogen production from surplus renewable energy and hydrogen transportation using existing natural gas pipelines are effective means to mitigate renewable energy fluctuation, build a decarbonized gas network, and achieve the goal of carbon peak and carbon neutral in China. This paper proposes a quasi-steady-state modeling method of a hydrogen blended integrated electricity-gas system (HBIEGS) considering gas linepack and a sequential second-order cone programming (S-SOCP) method to solve the developed model. The results show that the proposed method improves computational efficiency by 91% compared with a general nonlinear solver.

Summary: This paper introduces a novel multi-task learning data-driven model called GBLS Booster for accurately assessing the state of health (SOH) and remaining useful life (RUL) of lithium batteries. The model combines the strengths of GBLS and the CNN-Transformers algorithm-based Booster, and the Tree-structured Parzen Estimator (TPE) algorithm is used for optimization. The study devises 10 healthy indicators (HIs) derived from readily available sensor data to capture variations in battery SOH. The random forest method (RF) is employed for feature refinement and data dimension reduction, while the complete empirical mode decomposition (CEEMDAN) method and the Pearson correlation coefficient are used for noise reduction and data point elimination in RUL prediction. The proposed model demonstrates exceptional accuracy, robustness, and generalization capabilities.
