“…As shown in Fig. 8, when applying a charging current of 0.6 C, the voltage of a single-cell battery increases rapidly at the beginning of the charging process and gradually stabilizes, allowing for a longer charging duration and a higher amount of energy to be stored [21]. This low-temperature charging strategy eliminates the need for preheating the battery before charging and helps maintain higher capacity in cold environments, making it a practical solution for low-temperature lithium-ion battery charging.…”

This paper explores the current research status of chargers and lithium-ion batteries in low-temperature environments. Based on this, it provides a detailed discussion and analysis of charger charging conditions, lithium-ion battery performance analysis, the correlation between low-temperature environments and charging, and optimization design strategies for charging in low-temperature environments. The study reveals that low-temperature environments distort charger current harmonics, disrupt the power supply capacity of the grid, and reduce fast charging conversion efficiency. The paper elucidates the lithium-ion battery lithiation mechanism, lithiation detection methods, and countermeasures for lithiation issues in low temperatures. Besides highlighting the various adverse effects of lithiation on low-temperature charging, it also points out the shortcomings of detection methods and proposes appropriate strategies to inhibit lithiation. Addressing charging issues in low-temperature environments, the paper introduces charging optimization design strategies involving temperature-modulated current charging and genetic algorithm optimization. This research offers theoretical guidance and technical support for the design and optimization of chargers and lithium-ion batteries in low-temperature environments, further advancing the development and application of low-temperature charging technology.

“…This may be factored by an overestimate of the specific surface of the cell affected by the imposed current density [43]. Additionally, it could be attributed to the aging of the cell since it was cycled for a certain period prior to the experiments [44]. However, in general, the current model is able to represent the electrochemical behavior of the cell during discharge.…”

Lithium-ion batteries (LIBs) have circumvented the energy storage landscape for decades. However, safety concerns about liquid–electrolyte-based LIBs have challenged their mobilization. Lithium polymer (LiPo) batteries have gained rising interest due to their high thermal stability. Despite an array of commercially available LiPo batteries, limited studies have ventured into modeling. Numerical simulations allow low-cost optimization of existing battery designs through parameter analysis and material configuration, leading to safer and more energy-efficient batteries. This work examined the electrochemical, thermal, and thermal runaway behavior of a lithium cobalt oxide cathode, graphite anode, and poly(vinylidene fluoride-hexafluoropropylene) electrolyte pouch-type LiPo battery using COMSOL Multiphysics®, and validated results with experimental data. The simulated potential curve exhibited strong agreement with experiment data, while the temperature profile during discharge displayed qualitative discrepancies rationalized by the reversible heat generation. Thermal runaway simulations via oven tests revealed that the highest heat generation is from the cathode–electrolyte reaction, while the solid electrolyte interface decomposition initiates the heat generation process. These results suggest a thorough selection of cathode and electrolyte material to heighten battery safety. Overall, the developed models can be utilized as design tools to investigate various chemistries and designs to estimate the behavior and performance of batteries.

“…3,4 Lithium ions are primarily inserted into the positive and negative electrodes to charge lithium-ion batteries, and a reasonable choice of charging control strategy can reduce battery polarization, maintain the dynamic balance of charging within the battery, prevent the phenomenon of overcharging, and ensure the safe use of the battery. [5][6][7] At present, for a lithium-ion single-cell battery, the commonly used charging strategies are constant currentconstant voltage (CC-CV) charging, pulse charging, multi-stage charging, and model-based charging, and many researchers and scholars have fully investigated the advantages, disadvantages, and scope of the application of different charging strategies. To solve the range anxiety phenomenon commonly found among electric vehicle (EV) owners, meet the needs for different charging performances of batteries, and enhance the overall charging efficiency of batteries, various charging methods must be used based on various charging requirements.…”
