Abstract:
Silicon is widely studied as a high-capacity lithium-ion battery anode. However, the pulverization of silicon caused by a large volume expansion during lithiation impedes it from being used as a next generation anode for lithium-ion batteries. To overcome this drawback, we synthesized ultrathin silicon nanowires. These nanowires are 1D silicon nanostructures fabricated by a new bi-metal-assisted chemical etching process. We compared the lithium-ion battery properties of silicon nanowires with different average diameters of 100[Formula: see text]nm, 30[Formula: see text]nm and 10[Formula: see t

Abstract:
This computational research study will compare the specific charge capacity (SCC) between lithium ions inserted into crystallized silicon (c-Si) nanowires with that of sodium ions inserted into amorphous silicon (a-Si) nanowires. It will be demonstrated that the potential energy V(r) within a lithium–silicon nanowire supports a coherent energy state model with discrete electron particles, while the potential energy of a sodium–silicon nanowire will be discovered to be essentially zero, and, thus, the electron current that travels through a sodiated silicon nanowire will be modeled as a free el

Abstract Li-ion batteries are extensively used in electronic devices, cell phones, new energy vehicle batteries, and other sectors, and they have a lot of promise in electric cars and other domains. With the development of the times, batteries with carbon as anode material can no longer meet the demand of electric vehicles and other fields for battery energy density. Silicon, one of the most potential anode materials, demonstrates extremely high theoretical battery energy density.

Here we report an approach to roll out Li-ion battery components from silicon chips by a continuous and repeatable etch-infiltrate-peel cycle. Vertically aligned silicon nanowires etched from recycled silicon wafers are captured in a polymer matrix that operates as Li+ gel-electrolyte and electrode separator and peeled off to make multiple battery devices out of a single wafer. Porous, electrically interconnected copper nanoshells are conformally deposited around the silicon nanowires to stabilize the electrodes over extended cycles and provide efficient current collection.

Abstract:
Silicon nanowires are appealing structures to enhance the capacity of anodes in lithium-ion batteries. However, to attain industrial relevance, their synthesis requires a reduced cost. An important part of the cost is devoted to the silicon growth catalyst, usually gold. Here, we replace gold with tin, introduced as low-cost tin oxide nanoparticles, to produce a graphite–silicon nanowire composite as a long-standing anode active material. It is equally important to control the silicon size, as this determines the rate of decay of the anode performance. In this work, we demonstrate how to contr

With the development of technology, graphite materials in traditional lithium batteries can no longer meet people’s needs due to their relatively low specific capacity, limited charging and discharging rates, and poor safety.

This research is a theoretical study that simulates the volume expansion of a prelithiated silicon nanowire during lithium-ion insertion and the application of an electric current. Utilizing density functional theory (DFT) the ground state energy Eg (x) of prelithiated silicon (LixSi) is defined as a function of the lithium-ion (Li+) concentration (x). As the Li+ are increased, Eg (x) become increasingly stable from x = 1.00 through x = 2.415 and decrease in stability as the lithium-ion concentration becomes x > 2.415 until full lithiation of the silicon nanowire is reached at x = 3.75.

In recent years, because of a more prominent power electrification, lithium-ion batteries (LIBs) have attracted more and more interest in the scientific community. The desire to increase the battery performance, capacity, and power density has led to the development of new electrode materials. Silicon has emerged as a prominent anode material for next-generation lithium-ion batteries because of its high capacity [1] (10 times higher than graphite) and energy density.

By using the CNT-M procedure, a partial Si infiltration of carbon nanotube frameworks results in porous three dimensional microscale shapes consisting of silicon-carbon nanotube composites.
