“…In Fig. 4c-e, the deconvoluted spectra of Ni, Co, and Mn are in close match with the previously reported works [41][42][43] and confirms that the chemical and valence states of 0.1-NCM material were not disturbed in the valence structure by coating effect. The core spectra of C 1s were deconvoluted into three peaks at the binding energies of 283 eV, 285.2 eV, and 288.3 eV representing the different chemical states of carbon such as C-C, C-N, and O-C=O respectively shown in Fig.…”

The nickel-rich layered Li[Ni0.8Co0.1Mn0.1]O2, popularly known as NCM811, is considered a high-performance cathode material in lithium-ion batteries (LIBs) due to its high specific capacity and energy density. However, because of its poor structural stability, it suffers from long-run performance in LIBs. The surface coating technique can enhance the performance of the NCM811 cathode by preventing its surface degradation during prolonged contact with electrolytes. Herein, we report a uric acid-derived nitrogen-doped carbon-coated NCM811 cathode to enhance the cathodic performance. The materials were prepared by a facile one-step calcination in which different weights of uric acid are mixed well with NCM811 through ball milling followed by sintering. The XRD peaks confirm the formation of a pure phase in both the bare and modified NCM811 materials. The morphological characteristics and coating thickness are observed by FE-SEM and FE-TEM analysis, respectively. Electrochemical characterizations such as galvanostatic charge-discharge (GCD), cyclic performance, and rate capability studies show that the 0.1-NCM811 material can effectively tailor the electrochemical performance of the cathode in LIBs. The capacity retention of 0.1-NCM811 material is 92.7% and 85.8% at 100 cycles in 0.1C and 300 cycles in 1C, respectively. The improved electrochemical performance of coated NCM811 cathode is associated with the effective coating of nitrogen-doped carbon which can hinder the electrode dissolution process while amplifying the ionic conductivity.

Intimately mixed MnO/Ni hybrid materials are synthesized using a two-step process; Pechini process followed by a high temperature reduction step. As-prepared materials were characterized by X-ray diffraction, transmission electron microscopy and electrochemical tests. (MnO) 1-x /(Ni) x hybrid materials with x=0, 0.2 and 0.5 mole ratios are electrochemically evaluated as anode materials for lithium-ion batteries. The battery tests conclusively show that the coulombic efficiency, capacity utilization factor, percentage capacity retention and high rate performance values of control MnO material are enhanced with the presence of nearby metallic Ni nanoparticles. Oxide/metal hybrid material could be a cheaper alternative to commonly known oxide/graphene system.

Electronic devices commonly use rechargeable Li-ion batteries due to their potency, manufacturing effectiveness, and affordability. Electrospinning technology offers nanofibers with improved mechanical strength, quick ion transport, and ease of production, which makes it an attractive alternative to traditional methods. This review covers recent morphology-varied nanofibers and examines emerging nanofiber manufacturing methods and materials for battery tech advancement. The electrospinning technique can be used to generate nanofibers for battery separators, the electrodes with the advent of flame-resistant core-shell nanofibers. This review also identifies potential applications for recycled waste and biomass materials to increase the sustainability of the electrospinning process. Overall, this review provides insights into current developments in electrospinning for batteries and highlights the commercialization potential of the field.
