“…Figure 10 shows the change in the battery temperature after eight cycles under the operation conditions of the regular lines. To ensure the battery is working properly during the actual operation, the operating temperature of the battery should be kept below 35 °C [7]. Figure 10 shows that the battery gradually reached a heat balance with the progression of time, and the temperature was stable at the end of the test.…”

“…Shuanglong Du et al [6] established a three-dimensional thermal model based on the finite element theory and lumped internal heat generation principle to investigate the relationship between the discharge rate, total heat generation, and depth of discharge for the LiFePO 4 battery. L H Saw et al [7] established an empirical equation to describe the electrical characteristics of lithium-ion batteries, as well as a coupled lumped parameter thermal model to describe the thermal characteristics of the battery. The temperature of the battery was studied under the conditions of the driving cycles of the Urban Dynamometer Driving Schedule (UDDS), Highway Fuel Economy Driving Schedule (HWFET), and US06 Supplemental Federal Test Procedure (SFTP) to determine the flow rate of the cooling air that realizes the optimum thermal management of the battery system.…”

This study investigated the heat problems that occur during the operation of power batteries, especially thermal runaway, which usually take place in high temperature environments. The study was conducted on a ternary polymer lithium-ion battery. In addition, a lumped parameter thermal model was established to analyze the thermal behavior of the electric bus battery system under the operation conditions of the driving cycles of the Harbin city electric buses. Moreover, the quantitative relationship between the optimum heat transfer coefficient of the battery and the ambient temperature was investigated. The relationship between the temperature rise (T r ), the number of cycles (c), and the heat transfer coefficient (h) under three Harbin bus cycles have been investigated at 30 • C, because it can provide a basis for the design of the battery thermal management system. The results indicated that the heat transfer coefficient that meets the requirements of the battery thermal management system is the cubic power function of the ambient temperature. Therefore, if the ambient temperature is 30 • C, the heat transfer coefficient should be at least 12 W/m 2 K in the regular bus lines, 22 W/m 2 K in the bus rapid transit lines, and 32 W/m 2 K in the suburban lines.

“…The heat generation in the Li-ion battery constitutes ohmic heat, irreversible heat, and reversible heat [12]. Reaction heat or irreversible heat generation is due to the transfer of electrons to or from the electrode during the electrochemical reaction, reversible heat generation is because of the entropy changes of cathode and anode, and ohmic heat generation is due to the ohmic resistance of the solid active materials and electrolyte [12].…”

A new design of thermal management system for lithium ion battery pack using thermoelectric coolers (TECs) is proposed. Firstly, the 3D thermal model of a high power lithium ion battery and the TEC is elaborated. Then the model is calibrated with experiment results. Finally, the calibrated model is applied to investigate the performance of a thermal management system for a lithium ion battery pack. The results show that battery thermal management system (BTMS) with TEC can cool the battery in very high ambient temperature. It can also keep a more uniform temperature distribution in the battery pack than common BTMS, which will extend the life of the battery pack and may save the expensive battery equalization system.

As the energy crisis turning out to be more and more serious, an interest in renewable energy sources is also increasing. [3] Researchers around the world have been devoting themselves to developing a high-performance electric energy storage material [4] to meet the demand for ecofriendly, sustainable, and low-cost energy. Among several kinds of electrical energy storage systems, lithiumion batteries have been developed as largescale energy storage units [5] and energy storage medium in electric vehicles, [6] smart grids, and other clean energy systems such as solar and wind since 1990s. [7] The lithium ion battery is identified as one of the ideal candidates to meet these requirements due to its desired energy density, superior voltage, and light weight. [8] However, extensive application of lithium ion batteries faces challenges related to the availability and cost of lithium. Scientists have their eyes on making sodium ion batteries as an alternative, because sodium is more abundant than lithium. Except that, it is also cheaper and easy to recover. [9] So nowadays, studying new kinds of electrode materials for lithium ion batteries and sodium ion batteries can be a rewarding work.During the last few decades, LiFePO 4 has attracted much attention, which was reported as a positive electrode for rechargeable lithium ion batteries first by Good-enough and co-workers in 1990s. [10] Nowadays, thousands of research publications have been authored on LiFePO 4 , [11] such as graphene-encapsulated LiFePO 4 composite, [12] pure LiFePO 4 , and LiFePO 4 /C, [13] 3D porous LiFePO 4 , [14] olivine LiFePO 4 , [15] mesoporous carboncoated LiFePO 4 , [16] graphene-modified LiFePO 4 , [17] LiFePO 4 / reduced graphene oxide hybrid, [18] and so on. LiFePO 4 owns favorable kinetics of the lithium intercalation/deintercalation process [19,20] and its nanocrystal size and shape can be easily controlled, [21] especially when it is complexed with carbon-based materials or other elements, the electrochemical properties of the composite material can be greatly improved. [22,23] It also has advantages of atop safety, environmental friendliness, affordability, as well as its comparatively reasonable electrochemical performance. [24][25][26][27] Until now, many researchers have examined LiFePO 4 as next generation cathode material. [28] Since FePO 4 also shows intrinsically poor ionic and electrical conductivity, small tap density which influences its electrochemical performance, [29] LiFePO 4 will not be further discussed in this article.High-performance electric energy storage material has recently developed due to the attention for sustainable development. As ecofriendly energy storage device, lithium ion batteries and sodium ion batteries deserve more concern today. FePO 4 and NaFePO 4 share similar advantages such as easy preparation, abundant, and inexpensive, so they can be ideal materials for lithium/sodium ion batteries. This review is focused on recent progresses in nanostructured FePO 4 /NaFePO 4 -based nanomaterial as cathode ma...
