A Review of Recent Advancements in Electrospun Anode Materials to Improve Rechargeable Lithium Battery Performance

Abstract

Although lithium-ion batteries have already had a considerable impact on making our lives smarter, healthier, and cleaner by powering smartphones, wearable devices, and electric vehicles, demands for significant improvement in battery performance have grown with the continuous development of electronic devices. Developing novel anode materials offers one of the most promising routes to meet these demands and to resolve issues present in existing graphite anodes, such as a low theoretical capacity and poor rate capabilities. Significant improvements over current commercial batteries have been identified using the electrospinning process, owing to a simple processing technique and a wide variety of electrospinnable materials. It is important to understand previous work on nanofiber anode materials to establish strategies that encourage the implementation of current technological developments into commercial lithium-ion battery production, and to advance the design of novel nanofiber anode materials that will be used in the next-generation of batteries. This review identifies previous research into electrospun nanofiber anode materials based on the type of electrochemical reactions present and provides insights that can be used to improve conventional lithium-ion battery performances and to pioneer novel manufacturing routes that can successfully produce the next generation of batteries.

Electrochemical Performance of Thick-Film Li(Ni0.6Mn0.2Co0.2)O2 Cathode with Hierarchic Structures and Laser Ablation

“…Lithium-ion batteries (LIBs) are widely used in daily life for electric vehicles, mobile applications, and electric energy storage devices [1,2]. Although they had been making our lives convenient and clean, their charge and discharge capacity needed to be improved with the development of electronic devices [3]. The cathode and anode can influence the electrochemical performance of LIBs.…”

Stoichiometry Dependence of Physical and Electrochemical Properties of the SnOx Film Anodes Deposited by Pulse DC Magnetron Sputtering

“…The metallic Sn provided a high voltage of 1.6-2.5 V for SEI formation, which has been testified by an in situ AFM observation [68]. (2) The reduction peaks located in the range of 0.80-0.01 V corresponded to a series of Li−Sn alloying reactions, and the peak shape changed abnormally with the increase in the cycle numbers. For example, the SnO x film deposited at the condition of Ar/O 2 = 26/4 (Figure 5g) showed a special peak at 0.21 V, and its intensity increased with the cycle number particularly; this is explained by the cluster growth of metallic Sn nanoparticles.…”

“…Moreover, two oxidation states corresponding to the Sn 4+ (SnO 2 ) and Sn 2+ (SnO) are easily distinguished. (2) The oxygen element at the dominant peak of ≈530.9 eV comes from lattice oxygen (O L ), namely, the Sn−O−Sn bond [42,44]. (3) Another one resolved at ≈530.1 eV is associated with the O 2− ions in the oxygen-deficient regions (O V ) [48,51]; O L and O V are also separated by ≈0.8 eV, and this is attributed to the incomplete oxidation state [45].…”

“…Tin oxide (SnO x ) has been applied as a promising anode since the Fuji Co. first proposed the use of SnO x in lithium–ion batteries [ 1 , 2 ]. Although SnO x possesses better cycle performance than the pure Sn electrode [ 3 ], it still suffers the problems of irreversible capacity loss and rapid capacity decay arising from the mechanical failure (e.g., cracking, pulverization and disconnection) during discharge/charge cycles [ 4 , 5 ].…”

Electrospun Functional Nanofiber Membrane for Antibiotic Removal in Water: Review

“…Figure 7 simply summarizes the top view structure of the spinnerets. Fibers with complex nanostructures can be prepared through multifluid electrospinning and can be used in different fields, such as drug release [ 92 , 93 , 94 , 95 , 96 , 97 , 98 , 99 ], tissue engineering [ 100 ], lithium battery energy storage [ 101 , 102 ], antibacterial [ 103 , 104 ] and environmental remediation [ 105 , 106 ]. However, only few studies focused on the use of multifluid electrospinning to prepare functional fiber membranes for water treatment applications.…”
