Fabrication of Cu₂O-based Materials for Lithium-Ion Batteries

Abstract

The improvement of the performance of advanced batteries has played a key role in the energy research community since its inception. Therefore, it is necessary to explore high-performance materials for applications in advanced batteries. Among the variety of materials applied in batteries, much research has been dedicated to examine cuprous oxide materials as working electrodes in lithium cells to check their suitability as anodes for Li-ion cells and this has revealed great working capacities because of their specific characteristics (polymorphic forms, controllable structure, high cycling capacity, etc.). Thus, cuprous oxide and its composites will be fully introduced in this Review for their applications in advanced batteries. It is believed that, in the future, both the study and the impact of cuprous oxide and its composites will be much more profound and lasting.

Metal–Organic Framework‐Based Sulfur‐Loaded Materials

“…Lithium-ion batteries (LIBs), as classic rechargeable battery systems, have become vital energy storage systems in our everyday lives since their commercialization. [1][2][3][4][5][6][7][8][9][10][11] However, LIBs cannot fully satisfy the rapidly growing market demand because the energy density that can be achieved with the current systems is approaching its limit. [12][13][14][15][16][17][18][19] Therefore, development of alternative advanced electrical energy storage devices that can provide high energy densities has become a research hotspot.…”

A Hierarchically Porous ZIF@LDH Core‐Shell Structure for High‐Performance Supercapacitors

“…[1][2][3][4] Common electricity-storage systems are based on batteries, such as lithium-ion batteries, lithiumsulfur batteries and aluminum-ion batteries. [5][6][7] In a variety of energy storage systems, supercapacitors, which are between conventional capacitors and batteries, have attracted widespread attention because of their fast charge and discharge speed, high power density, and long cycle life. [8][9][10][11] As well known, there are two categories of supercapacitors in view of energy storage mechanism.…”

Curtailing the Overpotential of Li–CO2 Batteries with Shape‐Controlled Cu2O as Cathode: Effect of Illuminating the Cathode

“…Cu oxides, namely,c upric (CuO) and cuprous (Cu 2 O),h ave demonstrated interesting properties in the fields of catalysis and sensinga nd as negative electrodes in LIBs. [15,16] In particular,surface-modified octahedral Cu 2 Oh as been used as an egative electrode in LIBs and shows high specific capacity as well as good rate and long-term cycle performance. [17] In the attempt of addressing the issue of sluggish oxygen reactions in MABs, Cu 2 Oa nd carbon composites have been utilized to address the issue of sluggish oxygen reactions in MABs, and results showed that they can limit the cycling voltage to 2.5 and 3.7 Ve ven after 100 cycles.…”
