“…One concern in cylindrical lithium-ion batteries is electrolyte leakage [8][9][10]. Loss of electrolyte can lead to batteries drying out, which can result in capacity reduction, performance degradation, and safety hazards [11]. The electrolyte in a lithium-ion battery enables the movement of lithium ions between the positive and negative electrodes during charging and discharging.…”

“…The electrolyte usually consists of lithium salts, organic solvents, and additives [12]. When the electrolyte leaks, in addition to deteriorating the battery's capacity and performance, the leaked electrolyte can react with the moisture in the air and generate hydrofluoric acid (HF), which can corrode the electrode's active materials [11].…”

In transportation and operation, lithium-ion batteries can be exposed to environments where the temperature exceeds 75 °C, compromising seal integrity and leading to electrolyte leakage and safety issues. Standards introduced by regulatory bodies require temperature testing, including temperature cycling tests. This study examines cylindrical battery electrolyte leakage due to temperature cycling between 25 °C and 80 °C through capacity tests, electrochemical impedance spectroscopy, computed tomography scans, and thermal analysis. Different thermal expansions among battery cap elements were identified as the cause of leakage. The thermal test parameters and requirements in the UN Manual of Tests and Criteria Section 38.3 were reviewed, revealing the 72 °C upper-temperature limit and the 24 h storage period after temperature cycling fail to effectively qualify lithium-ion batteries for real-world applications.

Precise prediction of lithium‐ion cell level aging under various operating conditions is an imperative but challenging part of ensuring the quality performance of emerging applications such as electric vehicles and stationary energy storage systems. Accurate and real‐time battery‐aging prediction models, which require an exact understanding of the degradation mechanisms of battery components and materials, could in turn provide new insights for materials and battery basic research. Furthermore, the primary barrier to meaningful artificial intelligence/machine learning for accelerating the prediction period is the exploitation of accurate aging mechanistic descriptors. This review comprehensively summarizes the evolution of deterioration mechanisms at the material and cell level in different environments and usage scenarios, including the intricate relationships between aging mechanisms, degradation modes, and external influences, which are the cornerstones of modeling simulation and machine learning techniques. Recent advances in electrochemical models coupled with internal battery degradation mechanisms as well as identification and tracking of aging parameters are shown, with particular emphasis on electrode balance and the anticipated trend of machine learning‐assisted reliable remaining useful life prediction. Precise simulation prediction of cell level aging will continue to play an essential role in advanced smart battery research and management, enhancing its performance while shortening experimental sequences.

In recent years, aqueous zinc ion batteries (ZIBs) with ultra‐high safety and environmental friendliness have emerged as a promising candidates for energy storage and energy conversion devices. However, the severe side reactions and dendrites issues discourage the practical application of ZIBs. Recently, biopolymer‐based gel electrolytes have disclosed large potential in tackling these challenges of ZIBs, with numerous advancements reported. Their advantages lie in suppressing side reactions including hydrogen evolution and Zn metal anode corrosion, as well as inhibiting the growth of Zn dendrites. This review comprehensively examines the classification, structures and properties of biopolymer‐based gel electrolytes, with a focus on hydrogel electrolytes derived from various natural macromolecular biopolymers, along with a brief discussion on non‐hydrogel electrolytes using ionic liquids or organic solutions as solvents. Subsequently, the preparation of biopolymer‐based gel electrolytes with physical and chemical methods are summarized. Furthermore, the practical applications of biopolymer‐based gel electrolytes in ZIBs with diverse cathodes materials are introduced. Finally, it highlights the environmental benefits and excellent electrochemical performance of biopolymer‐based gel electrolytes, outlining their prospects for the next generation of ZIBs and proposing future perspectives.
