NiO/NiFe2O4 nanocubes derived from Prussian blue as anode materials for Li-ion batteries

A metal–organic framework approach to engineer mesoporous ZnMnO3/C towards enhanced lithium storage

“…Although different scanning speeds were applied, the CV curves showed similar shapes, indicating that the degree of polarization was very small. 50,51 However, comparing the curves at various scanning speeds separately, it could be observed that the peak value of the curve and the scanning speed presented a trend of change in the same direction, i.e., as the scanning speed was raised, the peak value of the curve also increased (Fig. 5a).…”

Advances on Nickel-Based Electrode Materials for Secondary Battery Systems: A Review

“…66,67 Using Prussian blue as a self-sacrificial template, Yao's group synthesized NiO/ NiFe 2 O 4 , which retained the cubic structure and alleviated the serious volume expansion phenomenon of NiFe 2 O 4 effectively. 62 The reversible capacities of NiO/NiFe 2 O 4 were 944, 779, 630, and 604 mA h g −1 at the current densities of 0.1, 0.2, 0.5, and 1.0 A g −1 , respectively. Nevertheless, with Fe 2 O 3 as the electrode material, the formation of Fe probably reduced the capability of energy storage.…”

“…Compared to mono-metal oxide, binary metal oxides possessed better electrical conductivity and electrochemical activity. The enhancement of the above properties was attributed to the different charge and discharge potentials of the two metal ions in binary metal oxides, making them act as buffer substances for each other. , Using Prussian blue as a self-sacrificial template, Yao’s group synthesized NiO/NiFe 2 O 4 , which retained the cubic structure and alleviated the serious volume expansion phenomenon of NiFe 2 O 4 effectively . The reversible capacities of NiO/NiFe 2 O 4 were 944, 779, 630, and 604 mA h g –1 at the current densities of 0.1, 0.2, 0.5, and 1.0 A g –1 , respectively.…”

Modern practices in electrophoretic deposition to manufacture energy storage electrodes

“…In particular, capacity fading is a serious issue suffered from nickel ferrite anode materials and therefore various approaches have been tried and tested in the literature to circumvent this, for example, encapsulation by means of carbonaceous substances in addition to applying a range of binders. 153 However, the complexity and expenses associated with scaling-up is not a practical solution for industrial applications. In contrast, EPD is a facile method that can be scaled-up on demand and can produce uniform deposition of LiB electrode materials with good porosity networks as reviewed very recently.…”

“…It is also worth mentioning that one of the latest publications on conversion‐type anodes for lithium half‐cell application 147 mentions about the drawbacks of such systems involving transition metal oxides. In particular, capacity fading is a serious issue suffered from nickel ferrite anode materials and therefore various approaches have been tried and tested in the literature to circumvent this, for example, encapsulation by means of carbonaceous substances in addition to applying a range of binders 153 . However, the complexity and expenses associated with scaling‐up is not a practical solution for industrial applications.…”
