“…Depending on the method of packaging, batteries can have a coin, cylindrical, prismatic, or pouch shape. According to Li's work, 26 the large format pouch-type cells are widely used for high power applications. Compared with the coin-type half cells whose anode electrode is lithium metal, the pouch-type full cells are cheaper, safer, more practical and relevant to Li-ion battery devices.…”

We demonstrated a one-step synthesis method for a novel gel polymer electrolyte (named PDMP-Li GPE) based on 3-(dimethylamino) propyl methacrylate, poly(ethylene glycol) diacrylate and 1 M LiPF 6 liquid electrolyte solution by a g-radiation technique for lithium-ion batteries. The resultant PDMP-Li GPE exhibited good thermal stability, excellent mechanical strength and high ionic conductivity, and the highest ionic conductivity reached 8.88 Â 10 À3 S cm À1 at 25 C. The LiFePO 4 /PDMP-Li GPE/graphite pouch-type cell exhibited more than 97% columbic efficiency and the capacity retention was about 86% after 50 cycles at 0.1C. With these outstanding characteristics, it is expected to be a promising candidate for the application in polymer lithium-ion batteries.Scheme 1 The synthesis route of 3-(dimethylamino) propyl methacrylate (DMAPMA).Scheme 2 Schematic illustration of the preparation of the PDMP-Li GPE.

“…Fick's diffusion coefficient D depends on the temperature, as expressed by the following equation: (15) Diffusion phenomena have two main effects on the performance of a Li-ion battery. On the one hand, the ion diffusion through the crystal lattice in the electrodes creates a difference between the ion concentration at the electrode-electrolyte interphase, and the average electrolyte concentration, Li c .…”

The growing interest in e-mobility and the increasing installation of renewable energy-based systems are leading to rapid improvements in lithium-ion batteries. In this context, battery manufacturers and engineers require advanced models in order to study battery performance accurately. A number of Li-ion battery models are based on the representation of physical phenomena by electrochemical equations. Although providing detailed physics-based information, these models cannot take into account all the phenomena for a whole battery, given the high complexity of the equations. Other models are based on equivalent circuits and are easier to design and use. However, they fail to relate these circuit parameters to physical properties. In order to take the best of both modeling techniques, we propose an equivalent circuit model which keeps a straight correlation between its parameters and the battery electrochemical principles. Consequently, this model has the required simplicity to be used in the simulation of a whole battery, while providing the depth of detail needed to identify physical phenomena. Moreover, due to its high accuracy, it can be used in a wide range of environments, as shown in the experimental validations carried out in the final section of this paper.

“…Myung et al 5 7 have predicted the voltage-capacity behavior of a primary LiB with a blended cathode constructed with high energy active material (CF x ) and high power active material (SVO) through a mathematical approach. Li et al 13 have developed a reduced order model of LiB with blended cathode. Although his equilibrium model is useful and effective for quick evaluation of the capacity and voltage profile of a blended electrode, it lacks the capability of dynamic simulation.…”

Summary Instead of developing a new battery to meet required specifications of an automotive battery pack, different batteries can be combined to construct a hybrid battery module to simultaneously achieve both high power and high energy densities in a single system. To investigate the feasibility of battery hybridization concept, a circuit‐based hybrid battery model similar to physics‐based, blended‐electrode model is developed. Our simulation results confirm that the hybrid battery model shows good agreement with physics‐based model. Prototype hybrid battery modules consisting of two different lithium‐ion batteries are constructed according to various configurations. A computational model representing the constructed hybrid battery module is developed for model validation. Our experimental results show that the capacity and power of a battery module can be controlled by combining different batteries. The computational model of the hybrid battery shows good agreement with experimental results, confirming high fidelity of the proposed model.
