As electric vehicle market growing fast, lithium ion batteries demand is increasing rapidly. Sufficient battery materials supplies including cathode, anode, electrolyte, additives, et al. are required accordingly. Although layered cathode is welcome in high energy density batteries, it is challenging to balance the high energy density and safety beside cost. As consequence, olivine phosphate cathode is coming to the stage center again along with battery technology development. It is important and necessary to revisit the olivine phosphate cathode to understand and support the development of electric vehicles utilized lithium ion batteries. In addition, blend cathode is a good strategy to tailor and balance cathode property and performance. In this chapter, blend cathode using olivine phosphate cathode will be discussed as well as olivine phosphate cathode.

Abstract The development of electric vehicles has made massive progress in recent years, and the battery part has been receiving constant attention. Although lithium-ion battery is a powerful energy storage technology contemporarily with great convenience in the field of electric vehicles and portable/stationary storage, the scantiness and increasing price of lithium have raised significant concerns about the battery’s developments; an alternative technology is needed to replace the expensive lithium-ion batteries at use. Therefore, the sodium-ion batteries (SIBs) were brought back to life. Sharing a similar mechanism as the lithium-ion batteries makes SIBs easier to understand and more effective in the research. In recent years, the developed materials for anode and cathode in the SIB have extensively promoted its advancements in increasing the energy density, power rate, and cyclability; multiple types of electrolytes, either in the form of aqueous, solid, or ions, offers safety and stability. Still, to rival the lithium-ion batteries, the SIB needs much more work to improve its performance, further expanding its application. Overall, the SIB has tremendous potential to be the future leading battery technology because of its abundance.

Olivine Structure

Lithium ion battery technology has played a key role in portable electronics revolution, and it is vigorously pursued for electric vehicle applications. LiFePO4 has recently received a great deal of attention due to its potential usage as a next-generation cathode material for lithium-ion batteries such as power tools, electric vehicles (EVs)and hybrid electric vehicles (HEVs),etc.LiFePO4 is advantageous when comparing other conventional cathode materials such as LiCoO2, LiNiO2 and LiMn2O4, namely, it is inexpensive, environmentally benign and thermally stable, etc.. In the present work, LiFePO4 has been prepared using polyol method and its crystal structure has been confirmed by powder X-ray diffraction. The as-prepared LiFePO4 has olivine structure with space group Pnma and orthorhombic lattice parameters are calculated as a=10.3999Å, b=6.0070Å and c=4.6388Å. The functional group vibrations have been analyzed using Fourier Transform Infrared Spectroscopy (FT-IR). The surface morphology of synthesized material have been studied by scanning electron microscopy (SEM) and the compositional analysis were also been carried out through EDX analysis.

Electric vehicles (EVs) are being endorsed as the uppermost successor to fuel-powered cars, with timetables for banning the sale of petrol-fueled vehicles announced in many countries. However, the range and charging times of EVs are still considerable concerns. Fast charging could be a solution to consumers’ range anxiety and the acceptance of EVs. Nevertheless, it is a complicated and systematized challenge to realize the fast charging of EVs because it includes the coordinated development of battery cells, including electrode materials, EV battery power systems, charging piles, electric grids, etc. This paper aims to serve as an analysis for the development of fast-charging technology, with a discussion of the current situation, constraints and development direction of EV fast-charging technologies from the macroscale and microscale perspectives of fast-charging challenges. If the problem of fast-charging can be solved, it will satisfy consumers’ demand for 10-min charging and accelerate the development of electric vehicles. This paper summarized the development statuses, issues, and trends of the macro battery technology and micro battery technology. It is emphasized that to essentially solve the problem of fast charging, the development of new battery materials, especially anode materials with improved lithium ion diffusion coefficients, is the key. Finally, it is highlighted that red phosphorus is one of the most promising anodes that can simultaneously satisfy the double standards of high-energy density and fast-charging performance to a maximum degree.

Lithium ion battery is the most widely used and reliable power source for electric vehicles. With the development of electric vehicles, the safety, energy density, life and reliability of lithium ion batteries have been continuously improved. However, in the field of vehicle power battery technology, battery monomers are combined in series and parallel to provide enough energy, but one of the major problems faced by group batteries is the consistency between battery monomers. Taking the capacity increment curve (IC curve) of lithium iron phosphate battery as the analysis tool, it is found that the characteristic peak of IC curve of different monomers in battery pack can reflect the relationship of monomer capacity. On this basis, the mathematical model is established, and the IC curve II peak characteristic point of a single cell are used as the reference to characterize the capacity of the single cell one by one. The results show that the method can be used in the normal charging process of the battery pack, and the capacity of the single cell in the battery pack can be characterized in real time during the whole life of the battery pack. It has certain research value for the ladder utilization and accurate management of battery pack.

Electric vehicles (EV), including plug-in hybrid and extend-range EVs, rely on high power and high capacity batteries, such as lithium-ion batteries, as the main source of propulsion energy. The EV battery technology is progressing rapidly as a plurality of battery designs in cells, modules and packs are emerging on the market. Current EV battery pack assembly is mostly manual and has faced significant challenges in coping with such fast development of automotive batteries. Meanwhile, there is a lack of systematic study on the implications of varieties in battery designs on assembly system. This paper reviews various battery module or pack designs and characterizes them from the assembly process perspective, and discusses their implications with respect to assembly methods, process flexibility and automation feasibility. The associated cost, quality, and safety issues of assembly are also addressed and research opportunities and innovations are discussed. This study can assist in creating guidelines on the development of new generations of battery products that enables highly efficient and responsive battery assembly.
