“…In the XPS of LiZrO 2 , the detection of a smaller peak at 53.14 eV has been assigned to metallic lithium (Li 1s), and the appearance of another peak with relatively high intensity at 54.01 eV is corresponded to the binding of Li with oxygen (from ZrO 2 ) . The binding energy difference between the two signals is about 3.0 eV, agreeing with the published report . Besides, some minor peaks were observed associated with C as impurities from precursors as well as from the XPS chamber contamination.…”

The capture and storage of CO2 are of growing interest in atmospheric science since greenhouse gas emission has to be reduced considerably in the near future. The present paper deals with the doping of cations on ZrO2, i.e., M-ZrO2 (M = Li+, Mg2+, or Co3+), defecting the crystalline planes for the adsorption of carbon dioxide. The samples were prepared by the sol–gel method and characterized completely by different analytical methods. The deposition of metal ions on ZrO2 (whose crystalline phases: monoclinic and tetragonal are transformed into a single-phase such as tetragonal for LiZrO2 and cubic for MgZrO2 or CoZrO2) shows a complete disappearance of the XRD monoclinic signal, and it is consistent with HRTEM lattice fringes: 2.957 nm for ZrO2 (101, tetragonal/monoclinic), 3.018 nm for tetragonal LiZrO2, 2.940 nm for cubic MgZrO2, and 1.526 nm for cubic CoZrO2. The samples are thermally stable, resulting an average size of ∼5.0–15 nm. The surface of LiZrO2 creates the oxygen deficiency, while for Mg2+ (0.089 nm), since the size of the atom is relatively greater than that of Zr4+ (0.084 nm), the replacement of Zr4+ by Mg2+ in sublattice is difficult; thus, a decrease of the lattice constant was noticed. Since the high band gap energy (ΔE > 5.0 eV) is suitable for CO2 adsorption, the samples were employed for the selective detection/capture of CO2 by using electrochemical impedance spectroscopy (EIS) and direct current resistance (DCR), showing that CoZrO2 is capable of CO2 capture about 75%. If M+ ions are deposited within the ZrO2 matrix, then the charge imbalance allows CO2 to interact with the oxygen species to form CO3 2– which produces a high resistance (21.04 × 106 (Ω, Ohm)). The adsorption of CO2 with the samples was also theoretically studied showing that the interaction of CO2 with MgZrO2 and CoZrO2 is more feasible than with LiZrO2, subscribing to the experimental data. The temperature effect (273 to 573 K) for the interaction of CO2 with CoZrO2 was also studied by the docking method and observed the cubic structure is more stable at high temperatures as compared to the monoclinic geometry. Thus, CO2 would preferably interact with ZrO2 c (E R S = −19.29 kJ/mol) than for ZrO2 m (22.4 J/mmol (ZrO2 c = cubic; ZrO2 m = monoclinic).

“…Strong absorption peaks observed at ~1011-1020 and ~1125-1145 cm À 1 are attributed to the LiÀ O stretching modes of Li 2 O in all the cycled samples. [45] In region-III (Figure 6d), the absorption peaks observed in the region at 1245-1253, and 1355 cm À 1 are attributed to symmetric stretching vibrations of BÀ O bond in BO 3 units for HM-100 electrodes. The shifting in peak positions of BÀ O and LiÀ O vibration bands in redox cycled HM-100 electrodes indicate that there might be a facile compound formation between LiÀ OÀ B which is also evidenced from ex-situ investigations by the presence of quasicrystal Li 4 B 2 O 5 (XRD) and boron presence in SEI layer (SEM).…”

Despite lithium-ion battery (LIB) and supercapacitor materials have gone through numerous enhancements, achieving high energy density as well as power density together is still a dream for the industries. In this scenario, herein we report, boric acid coated αÀ MnO 2 anode with 1288 mAh g À 1 at 0.1 C at the initial cycle and of an average discharge capacity of 570 mAh g À 1 at 0.1 C over 20 cycles, high-rate capability and 100 % Coulombic efficiency after 60 cycles for LIB. The Li + diffusion coefficient estimated from GITT and EIS measurements reveals that the H 3 BO 3 coated αÀ MnO 2 electrode has superior Li-ion kinetics ( D Li þ ~10 À 10 cm 2 s À 1 ) than bare αÀ MnO 2 . Coin cells with boric acid coated αÀ MnO 2 electrode are able to power up red and blue LEDs continuously for about 24-32 hours. The ex-situ investigations reveal an interesting self-assembled active electrodeelectrolyte interfacial bridging Li 4 B 2 O 5 layer formation. This significant active layer allows free migration of lithium ions across interface that leads to good cyclability. In flexible supercapacitor, the boric acid coated αÀ MnO 2 yields excellent cyclability over 500 cycles with specific capacitance of 35 F g À 1 at 1 A g À 1 and further 200 cycles at 30°acute angle with 21 F g À 1 at 1 A g À 1 . The research overthrows the significance of boric acid in conversion reactions for active interfacial bridging layer in LIB and hydroxyl ion capturing agent in flexible supercapacitor.

Developing 3D hosts is one of the most promising strategies for putting forward the practical application of lithium(Li)‐based anodes. However, the concentration polarization and uniform electric field of the traditional 3D hosts result in undesirable “top growth” of Li, reduced space utilization, and obnoxious dendrites. Herein, a novel dual‐gradient 3D host (GDPL‐3DH) simultaneously possessing gradient‐distributed pore structure and lithiophilic sites is constructed by an electrospinning route. Under the synergistic effect of the gradient‐distributed pore and lithiophilic sites, the GDPL‐3DH exhibits the gradient‐increased electrical conductivity from top to bottom. Also, Li is preferentially and uniformly deposited at the bottom of the GDPL‐3DH with a typical “bottom‐top” mode confirmed by the optical and SEM images, without Li dendrites. Consequently, an ultra‐long lifespan of 5250 h of a symmetrical cell at 2 mA cm−2 with a fixed capacity of 2 mAh cm−2 is achieved. Also, the full cells based on the LiFePO4, S/C, and LiNi0.8Co0.1Mn0.1O2 cathodes all exhibit excellent performances. Specifically, the LiFePO4‐based cell maintains a high capacity of 136.8 mAh g−1 after 700 cycles at 1 C (1 C = 170 mA g−1) with 94.7% capacity retention. The novel dual‐gradient strategy broadens the perspective of regulating the mechanism of lithium deposition.
