“…Nowadays, the latest research works have paid more attention to the increasing demand of energy storage devices in various fields, such as supercapacitors, electric vehicles, portable electronics, and lithium-ion batteries (LIBs) [ 1 , 2 , 3 , 4 , 5 ]. The LIBs, which possess significantly higher energy density compared to sodium-ion batteries, lead-acid batteries, and aqueous nickel-based systems, have become the dominant power storage device [ 6 , 7 , 8 , 9 , 10 ]. Many novel technologies have been applied to improve the cyclability and electrochemical performance of the anode materials for LIBs by designing and utilizing various nanostructures.…”

In this study, one-dimensional porous silicon nanowire (1D–PSiNW) arrays were fabricated by one-step metal-assisted chemical etching (MACE) to etch phosphorus-doped silicon wafers. The as-prepared mesoporous 1D–PSiNW arrays here had especially high specific surface areas of 323.47 m2·g−1 and were applied as anodes to achieve fast charge–discharge performance for lithium ion batteries (LIBs). The 1D–PSiNWs anodes with feature size of ~7 nm exhibited reversible specific capacity of 2061.1 mAh·g−1 after 1000 cycles at a high current density of 1.5 A·g−1. Moreover, under the ultrafast charge–discharge current rate of 16.0 A·g−1, the 1D–PSiNWs anodes still maintained 586.7 mAh·g−1 capacity even after 5000 cycles. This nanoporous 1D–PSiNW with high surface area is a potential anode candidate for the ultrafast charge–discharge in LIBs with high specific capacity and superior cycling performance.

“…No cell has ever been made with this combination of anode and cathode. One example does exist of a TiO 2 -V 2 O 5 composite by Zhou et al, [10] however in this work the TiO 2 was there as a suppourt only and provided no capacity. However both of the electrode materials can be examined individually.…”

“…In CV studies in the literature, the first two peaks are almost always seen, whereas the third peak is seen less often due to an apparent lower reversibility of this step [12]. The redox activity of V 2 O 5 is best seen in the work by Zhou et al, [10] in Figure 5.17. From these results it can be seen that there are 3 redox peaks associated with lithium intercalation into V 2 O 5 .…”

Microemulsion electrolytes for electrochemical energy storage devices

The demand for electrical energy storage technology is growing at a rapid pace. The current market leader is the lithium ion battery which has found use in many applications from stationary, grid level storage to transportation and smaller applications like mobile phones.Supercapacitors are an up-and-coming alternative energy storage technology that compliments lithium ion batteries in many ways. Where lithium ion batteries have a high energy density, delivering energy for a long time, supercapacitors have a high power density which means they are capable of being charged and discharged within seconds.Both of these technologies rely on organic electrolytes that are toxic and flammable. Replacing these organic electrolytes with alternatives would go a long way to improving their sustainability and lessening the environmental impact. Using a water based electrolyte is an attractive option however water is limited by its electrochemical window. Above a voltage of 1.23 V it is thermodynamically favourable for water to be split into hydrogen and oxygen gasses. This voltage restriction limits the energy density of water based batteries and supercapacitors making them economically non-viable. The research in this thesis was investigating the use of microemulsions as an alternative class of electrolytes in ion batteries and supercapacitors. Microemulsions are a thermodynamically stable mixture of two immiscible phases. Despite being mostly made up of water, microemulsions can have a greatly extended electrochemical window, as much as 5 V. This means that they could have all of the benefits of aqueous and organic electrolytes in one solvent. Microemsulions have never been applied to supercapacitors or ion batteries before. They were found to retain their enhanced electrochemical stability and still allow for the devices to perform. In almost all aspects the devices presented within out-perform any other water based electrolyte in the literature and in many cases show comparable performance to organic electrolytes.
