Lithium-ion batteries are currently used for various applications since they are lightweight, stable, and flexible. With the increased demand for portable electronics and electric vehicles, it has become necessary to develop newer, smaller, and lighter batteries with increased cycle life, high energy density, and overall better battery performance. Since the sources of lithium are limited and also because of the high cost of the metal, it is necessary to find alternatives. Sodium batteries have shown great potential, and hence several researchers are working on improving the battery performance of the various sodium batteries. This paper is a brief review of the current research in sodium-sulfur and sodium-air batteries.

Olivine Phosphate

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.

Safety Features

Abstract Lithium-ion batteries (LIBs), with relatively high energy density and power density, have been considered as a vital energy source in our daily life, especially in electric vehicles. However, energy density and safety related to thermal runaways are the main concerns for their further applications. In order to deeply understand the development of high energy density and safe LIBs, we comprehensively review the safety features of LIBs and the failure mechanisms of cathodes, anodes, separators and electrolyte. The corresponding solutions for designing safer components are systematically proposed. Additionally, the in situ or operando techniques, such as microscopy and spectrum analysis, the fiber Bragg grating sensor and the gas sensor, are summarized to monitor the internal conditions of LIBs in real time. The main purpose of this review is to provide some general guidelines for the design of safe and high energy density batteries from the views of both material and cell levels. Graphic Abstract Safety of lithium-ion batteries (LIBs) with high energy density becomes more and more important in the future for EVs development. The safety issues of the LIBs are complicated, related to both materials and the cell level. To ensure the safety of LIBs, in-depth understanding of the safety features, precise design of the battery materials and real-time monitoring/detection of the cells should be systematically considered. Here, we specifically summarize the safety features of the LIBs from the aspects of their voltage and temperature tolerance, the failure mechanism of the LIB materials and corresponding improved methods. We further review the in situ or operando techniques to real-time monitor the internal conditions of LIBs.

Mixed Electrolyte

Safety is the key-feature of high energy density lithium-ion batteries and thermal stability of the electrolytes is crucial. In this work, the thermal and flammability properties of mixed electrolytes based on the conventional ethylene carbonate (EC), dimethyl carbonate (DMC), ethyl methyl carbonate (EMC) (1:1:1 v/v/v), 1M LiPF6 and the hydrophobic ionic liquid (IL) N-methyl-N-propylpiperidinium bis (trifluoromethanesulfonyl) imide (Pp13TFSI) have been investigated. The mixed electrolyte is observed to be nonflammable at the Pp13TFSI contents of more than 40 vol.%. And physical and electrochemical characteristics of high energy density lithium ion batteries based on Li [Li0.2Mn0.54Ni0.13Co0.13]O2 as the cathode and artificial graphite as the anode with mixed electrolyte are also investigated. The cell of graphite/ Li [Li0.2Mn0.54Ni0.13Co0.13]O2 with 1 mol/L LiPF6/40%Pp13TFSI + 60% (EC+DMC+EMC) (1/1/1,v/v/v) electrolyte shows first charge capacity of 313.8 mAh g-1 and discharge capacity of 201.8 mAh g-1, respectively. Moreover, the nail penetration tests are carried out on the charged lithium-ion cells after formation, and the results show no explosion, ignition, or thermal runaway. These results suggest that the IL has potential to improve the safety of lithium ion batteries and can be used to fabricate the high energy density lithium ion batteries for electric vehicles and hybrid electric vehicles.

Lithium Ion Capacitor

Lithium-ion capacitors (LICs) have been widely explored for energy storage. Nevertheless, achieving good energy density, satisfactory power density, and stable cycle life is still challenging. For this study, we fabricated a novel LIC with a NiO-rGO composite as a negative material and commercial activated carbon (AC) as a positive material for energy storage. The NiO-rGO//AC system utilizes NiO nanoparticles uniformly distributed in rGO to achieve a high specific capacity (with a current density of 0.5 A g−1 and a charge capacity of 945.8 mA h g−1) and uses AC to provide a large specific surface area and adjustable pore structure, thereby achieving excellent electrochemical performance. In detail, the NiO-rGO//AC system (with a mass ratio of 1:3) can achieve a high energy density (98.15 W h kg−1), a high power density (10.94 kW kg−1), and a long cycle life (with 72.1% capacity retention after 10,000 cycles). This study outlines a new option for the manufacture of LIC devices that feature both high energy and high power densities.
