“…NiO film prepared by an electro‐deposition method showed an overpotential of 450 mV at 1 mA cm −2 for OER in 1 M potassium hydroxide (KOH) . However, further performance improvement of NiO‐based materials is restricted by poor electronic/ionic conductivity due to their semiconductor characteristics, which results in inferior electrode activity for OER and poor rate capability for LIBs . Furthermore, bulk NiO material also impedes the development of the NiO electrode because of large volume expansion during charge/discharge for LIBs and insufficient active sites for OER.…”

Transition metal oxides hold great promise for lithium‐ion batteries (LIBs) and electrocatalytic water splitting because of their high abundance and high energy density. However, designing and fabrication of efficient, stable, high power density electrode materials are challenging. Herein, we report rambutan‐like hollow carbon spheres formed by carbon nanosheet decorated with nickel oxide (NiO) rich in metal vacancies (denoted as h‐NiO/C) as a bifunctional electrode material for LIBs and electrocatalytic oxygen evolution reaction (OER). When being used as the anode of LIBs, the h‐NiO/C electrode shows a large initial capacity of 885 mA h g−1, a robust stability with a high capacity of 817 mA h g−1 after 400 cycles, and great rate capability with a high reversible capacity of 523 mA h g−1 at 10 A g−1 after 600 cycles. Moreover, working as an OER electrocatalyst, the h‐NiO/C electrode shows a small overpotential of 260 mV at 10 mA cm−2, a Tafel slope of 37.6 mV dec−1 along with good stability. Our work offers a cost‐effective method for the fabrication of efficient electrode for LIBs and OER.

“…However, the reduction of active materials could be improved by introducing (i) conductive binder such as pyrene‐based polymer and polyfluorene‐conjugated polymer, 14 and (ii) advanced conductive substrates, such as carbon cloth, graphene, and Ni foam 15‐18 . However, the weak interfacial bonding between of conventional PVDF or, conductive or, advanced conductive binders and active material such as NiO led to the particles self‐aggregated or/and isolated from current collector 19‐22 . Hence, LIBs with bindered NiO as anode exhibited low rate capability and cyclic life 9 .…”

In recent times, lithium-ion batteries (LIBs) are widely used in the fields of small electronic devices, wearable electronic devices, and automobiles. In the light of some current research on LIBs investigated on replacing commercial carbonaceous anode materials with transition metal oxides such as NiO due to its high theoretical capacity of 718 mAh g À1 . However, NiO still suffers from low cycling stability, low coulombic efficiency, and low rate capability resulting from large volume expansion and poor electrical conductivity which greatly limits the development of large-capacity LIBs. To overcome these barriers, various NiO electrodes with different morphologies and physical structures are developed. In this review, we introduce and summarize the electrochemical performances of binder-free NiO-Ni foam as anode of LIBs.

Three-dimensional (3D) porous metals have been applied as current collector to improve the cycle stability and high-rate capacities of lithium-ion battery due to they can accommodate volumetric changes of electrodes during lithium storage, and provide rapid transfer channels for lithium ions. NiO has attracted more and more attention due to its high theoretical specific capacity as anode of lithium-ion battery. However its low electrical conductivity and large volumetric changes during electrochemical cycling result in poor cyclability and low high-rate capacity. Besides, the large first irreversible capacity causing from the low reaction activity between the first lithiation products Ni 0 and Li 2 O, hinders its commercial application. In this work, we produce 3D porous Cu with interconnected pores (ca. 5 μm) by a facile and scalable electroless plating method and investigate its role on electrochemical storage improvement for NiO electrode. NiO@3D porous Cu is produced by electrodepositing Ni(OH) 2 film coupled with sequential high temperature with 3D porous Cu as the substrate. The NiO film deposited on the 3D porous Cu has mesoporous structure. This unique architecture can provide rapid transfer channels for lithium-ion battery and free place for accommodating volumetric changes of NiO during electrochemical cycling, meanwhile increases reactive points for Ni 0 and Li 2 O. Thus, this electrode demonstrates excellent high-rate capacity and high first columbic efficiency. The first discharge and charge capacities at 200 mA•g-1 are 1522.3 and 1230.2 mAh•g-1 respectively with high columbic efficiency of 80.8%. The same electrode shows high capacity of 578 mAh•g-1 at high current density of 20 A•g-1 , which is 48.8% of that at 0.2 A•g-1. The electrochemical impedance spectra (EIS) demonstrate the NiO@3D porous Cu electrode has smaller charge transfer resistance and large Li-ion diffusion efficiency compared with NiO@Cu foil. The SEM images show that the NiO@3D porous Cu electrode suffered 100 cycles remains well 3D porous structure. A full cell is assembled using NiO@3D porous Cu as negative electrode and LiNi 1/3 Co 1/3 Mn 1/3 O 2 as positive electrode. The full cell delivers first charge and discharge capacities of 1514 and 1060 mAh•g-1 respectively at 0.2 A•g-1 (based on NiO) with a coulomb efficiency of 70%, a first discharge capacity of 873 mAh•g-1 at 1.0 A•g-1 with 709 mAh•g-1 remained after 100 cycles (the retention is 81%). This work may offer an effective method for lithium storage enhancement of transition metal oxides.
