Nano and Battery Anode: A Review

Abstract

Improving the anode properties, including increasing its capacity, is one of the basic necessities to improve battery performance. In this paper, high-capacity anodes with alloy performance are introduced, then the problem of fragmentation of these anodes and its effect during the cyclic life is stated. Then, the effect of reducing the size to the nanoscale in solving the problem of fragmentation and improving the properties is discussed, and finally the various forms of nanomaterials are examined. In this paper, electrode reduction in the anode, which is a nanoscale phenomenon, is described. The negative effects of this phenomenon on alloy anodes are expressed and how to eliminate these negative effects by preparing suitable nanostructures will be discussed. Also, the anodes of the titanium oxide family are introduced and the effects of Nano on the performance improvement of these anodes are expressed, and finally, the quasi-capacitive behavior, which is specific to Nano, will be introduced. Finally, the third type of anodes, exchange anodes, is introduced and their function is expressed. The effect of Nano on the reversibility of these anodes is mentioned. The advantages of nanotechnology for these electrodes are described. In this paper, it is found that nanotechnology, in addition to the common effects such as reducing the penetration distance and modulating the stress, also creates other interesting effects in this type of anode, such as capacitive quasi-capacitance, changing storage mechanism and lower volume change.

A Review of High-Energy Density Lithium-Air Battery Technology: Investigating the Effect of Oxides and Nanocatalysts

“…e importance of studying the conductivity of this nanoparticle oxide stems from the fact that until our knowledge of the optimal conductivity of this oxide for different dimensions and morphologies is complete, it is not possible to optimize this oxide product by controlling battery performance such as current, geometry, cathode, and catalyst [149][150][151][152][153][154].…”

Dendrimer for targeted drug delivery and Vaccine and Immunostimulatory: applications and methods

“…Dendrimers have a good solution for complex ocular drug delivery problems [224]. In recent research, the shelf life of pilocarpine in the eye has been increased using Polyamidoamine dendrimers with carboxyl or hydroxyl surface groups [59,[225][226][227][228]].…”

“…Dendrimers have optimal characteristics to ll the need for e cient immunostimulating compounds (adjuvants) that can increase the e ciency of vaccines. This is because dendrimers can provide molecularly de ned multivalent scaffolds to produce highly de ned conjugates with small-molecule immunostimulators and/or antigens [225,[243][244][245][246]. The present paper gives an overview of the use of dendrimers as molecularly de ned carriers/presenters of small antigens, including constructs with built-in immunostimulatory (adjuvant) properties and standalone adjuvants that can be mixed with antigens to provide e cient vaccine formulations.…”

An Fe2O3/Mn2O3 Nanocomposite Derived from a Metal‐Organic Framework as an Anode Material for Lithium‐ion Batteries

“…By linking the heterojunction with MOFs, the electrode material can combine both advantages, not only the volume change is more moderate, but also the larger space brought by MOFs as a sacrificial template further relieves the volume expansion. In addition, the nano‐scale particles shorten the diffusion path of Li‐ions and electrons, which can improve the transfer rate of lithium ions and electrons [27] . All these make the new electrode materials have higher specific capacity and more stable cycle performance.…”

“…In addition, the nano-scale particles shorten the diffusion path of Li-ions and electrons, which can improve the transfer rate of lithium ions and electrons. [27] All these make the new electrode materials have higher specific capacity and more stable cycle performance.
