“…The reduction peak intensity of the second cycle is significantly lower than that of the first cycle, and the reduction peak of the second cathodic scan shifts to 1.17 V. High coincidence occurs in the reduction peaks of the second and third cathodic scan, indicating the excellent cycling stability of the CNO/GO microflowers. Oxidation peaks at 1.45 and 2.11 V of the first anodic scan correspond to the oxidation reaction of Co to Co 3 O 4 and Ni to NiO as well as the decomposition of Li 2 O. − …”

A graphene oxide-wrapped Co3O4/NiO (denoted as CNO/GO) micron flower is successfully synthesized by a rapid solvothermal method, which is formed through interpenetrating nanosheets. Nanosheets with a large specific surface area expose a large number of active sites for an electrochemical reaction. Moreover, abundant pores formed during the interpenetration of nanosheets are instrumental in providing enough buffer space to relieve the large volume expansion from the repeated lithium insertion/delithiation processes, and the tightly wrapped GO can effectively sustain the stability of the CNO micron flower structure during the long-term cycle processes. The reversible specific capacity as high as 602.9 mA h g–1 is maintained after 800 cycles at 5000 mA g–1. In addition, GO with good conductivity can greatly enhance the conductivity of CNO micron flowers, accelerate the transfer of electrons, and then achieve a high rate performance (the reversible specific capacity is 570.2 mA h g–1 at 10 000 mA g–1). This work provides a viable method for synthesizing the CNO micron flowers as a promising high-performance transition metal oxide anode for lithium-ion batteries.

“…Measurements of changes in electrode particle size and morphology after cycling using SEM imaging is common. [126,137,173,182,185,193] Due to its micron sized resolution, SEM can only image features at a particle scale. For crystallographic enhancements to be imaged, higher resolution TEM imagery must be taken.…”

Crystallographic features of battery active particles impose an inherent limitation on their electrochemical figures of merit namely capacity, roundtrip efficiency, longevity, safety, and recyclability. Therefore, crystallographic properties of these particles are increasingly measured not only to clarify the principal pathways by which they store and release charge but to realize the full potential of batteries. Here, state‐of‐the‐art advances in Li+, K+, and Na+ chemistries are reviewed to reiterate the links between crystallography variations and battery electrochemical trends. These manifest at different length scales and are accompanied by a multiplicity of processes such as doping, cation disorder, directional crystal growth and extra redox. In light of this, an emphasis is placed on the need for more accurate correlations between crystallographic structure and battery electrochemistry in order to harness crystallographic beneficiation into electrode material design and manufacture, translating into high‐performance and safe energy storage solutions.

“…As is well known, owing to the low initial Coulombic efficiency and capacity of carbon materials, exploring carbon-free electrode materials has been deemed as a hotspot worth studying. Therefore, significant progress has been made in the system of NiO@metallic oxide, including Fe 2 O 3 54 , TiO 2 , , Co 3 O 4 , − MnCo 2 O 4 59 , NiCo 2 O 4 , , NiFe 2 O 4 62 , and ZnCo 2 O 4 63 . TiO 2 , as a “zero-strain” material, acted as a template for the growth of NiO, resulting in the regular distribution of NiO. , As shown in Figure f, Zhang et al reported that hierarchical nonwoven fabric NiO/TiO 2 films act as an anode material for lithium-ion batteries.…”

“…Nevertheless, with Fe 2 O 3 as the electrode material, the formation of Fe probably reduced the capability of energy storage. Alternatively, numerous efforts have been devoted for Co 3 O 4 to explore electrode materials with attractive performance. − 3D labyrinth-like NiO–Co 3 O 4 @S was synthesized by Xu’s group to solve the problem of the dissolution of polysulfides in lithium-sulfur batteries, which presented an outstanding electrochemical performance (959 mA h g –1 at 1.0 A g –1 ). As shown in Figure g, owing to the special labyrinth-like structure of the material, the attenuation rate of each cycle is only 0.1% when it is cycled 200 times at 1.0 A g –1 …”

Captured by the high energy density and eco-friendly properties, secondary energy-storage systems have attracted a great deal of attention. For meeting with the demand of advanced systems with both cycling stability and high capacity, a series of tailoring methods have been used. Electrode materials, as the main components of a full cell, play importance roles in capacity contribution. Thus, exploring suitable materials has been deemed to be vital for the development of energy-storage systems. Recently, compared to the traditional carbon-based materials, the considerable electrochemical properties of metal-based samples have been observed. Alternatively, nickel-based materials displayed resource abundance, environmental-friendliness, and high theoretical specific capacity, while the rich exploring activities have been scarily summarized. In this review, the energy-storage performances of nickel-based materials, such as NiO, NiSe/NiSe2, NiS/NiS2/Ni3S2, Ni2P, Ni3N, and Ni(OH)2, are summarized in detail. For some materials with innovative structures, their merits and characteristics were discussed elaborately through four points: (1) the controlling of nanostructures, (2) the complexing of carbon materials, (3) the doping of heteroatoms, and (4) the designing of heterostructures. Significantly, the challenges and prospects of nickel-based materials for secondary battery systems are discussed. This work is expected to offer significant summarization and prospects about physical–chemical designing for nickel-based samples.
