“…[ 24 ] For instance, lithium plating over an anode can threaten lithium‐ion battery safety by overcharging. [ 25 ] The similar consequences of Zn plating and HER will cause internal pressure rise and swelling/cracking of the Zn‐ion battery under overcharge conditions. [ 24 ] Therefore, aside from the cycling stability, the overcharging factor is also noteworthy while evaluating battery performance.…”

Rechargeable hydrogen gas batteries are highly desirable for large‐scale energy storage because of their long life cycle, high round trip efficiency, fast reaction kinetics, and hydrogen gas profusion. Coupling advanced cathode chemistries with hydrogen gas anode is an emerging and exciting area of research. Here, a novel high‐performance aqueous iodine‐hydrogen gas (I2‐H2) battery using iodine as cathode and hydrogen gas as the electrocatalytic anode in environmentally benign aqueous electrolytes is reported. The working chemistry of the battery involves I2/I− solid‐liquid reactions occurring over the cathode along with H2/H2O gas‐liquid reactions at the anode, achieving a high rate performance of 100 C and long‐lasting stability of over 60 000 cycles. Additionally, the static aqueous I2‐H2 battery displays a volumetric capacity of 15.5 Ah L−1 along with good self‐healing capability towards cell overcharge. The current battery design exhibits robust electrochemical performance irrespective of acidic, neutral, and alkaline electrolyte systems. This study paves the way towards the industrialization of economically effective, high‐power density, and long‐term I2‐H2 batteries for large‐scale energy storage applications.

The present study aims to develop a simplified mathematical model for the evolution of heating-induced thermal runaway (TR) of lithium-ion batteries (LIBs). This model only requires a minimum number of input parameters, and some of these unknown parameters can be obtained from accelerating rate calorimeter (ARC) tests and previous studies, removing the need for detailed measurements of heat flow of cell components by differential scanning calorimetry. The model was firstly verified by ARC tests for a commercial cylindrical 21700 cell for the prediction of the cell surface temperature evolution with time. It was further validated by uniform heating tests of 21700 cells conducted with flexible and nichrome-wire heaters, respectively. The validated model was finally used to investigate the critical ambient temperature that triggers battery TR. The predicted critical ambient temperature is between 127 °C and 128 °C. The model has been formulated as lumped 0D, axisymmetric 2D and full 3D to suit different heating and geometric arrangements and can be easily extended to predict the TR evolution of other LIBs with different geometric configurations and cathode materials. It can also be easily implemented into other computational fluid dynamics (CFD) code.

“…First, since the incremental capacity is defined as the ratio of differential capacity to differential voltage ( dQ / dV ), its extraction could be much easier than acquiring the electrochemical properties online. Second, the IC trajectories can reflect the electrochemical mechanisms, such as Li-plating ( Mei et al., 2020 ) and intercalation of anions into the graphite-positive electrode ( Heidrich et al., 2019 ). Besides, ICA methods can also be integrated into the data-driven tools ( Berecibar et al., 2016 ), so that the aging-related features could be extracted more efficiently.…”

Summary The reliable assessment of battery degradation is fundamental for safe and efficient battery utilization. As an important in situ health diagnostic method, the incremental capacity (IC) analysis relies highly on the low-noise constant-current profiles, which violates the real-life scenarios. Here, a model-free fitting process is reported, for the first time, to reconstruct the IC trajectories from noisy or even current-varying profiles. Based on the results from overall 22 batteries with three case studies, the errors of the peak positions in the reconstructed IC trajectories can be bounded within only 0.25%. With health indicators extracted from the reconstructed IC trajectories, the state of health can be readily determined from simple linear mappings, with estimation error lower than 1% only. By enabling the IC-based methods under complex load profiles, enhanced health assessment could be implemented to improve the reliability of the power systems and further promoting a more sustainable society.
