Annotation:
The demand for high performance Lithium-ion batteries (LIBs) is increasing due to widespread use of portable devices and electric vehicles. Silicon (Si) is one of the most attractive candidate anode materials for the next generation LIBs because of its high theoretical capacity (3,578 mAh/g) and low operation potential (~0.4 V vs Li+/Li). However, the high volume change (>300%) during Lithium ion insertion/extraction leads to poor cycle life. The goal of this work is to improve the electrochemical performance of Si/C composite anode in LIBs. Two strategies have been employed: to explore spat

Coin cells with lithium and graphite electrodes were assembled using different combinations of graphite material and electrolyte. Specifically, three commercially available graphite materials and five electrolyte compositions were studied. The cells were discharge-charge cycled with varying parameters in order to determine the performance of the graphite materials and electrolytes. Particularly, a temperature chamber was employed to cycle some cells at temperatures between 0 and 40°C to find the significance of the electrolyte composition and graphite material on the cell performance at t

To develop high energy density lithium ion batteries, the use of new electrode materials is required. Germanium is among the possible alternatives to the most commonly used anode, graphite (372 mAh/g), thanks to its four-times higher theoretical gravimetric capacity (1600 mAh/g). Here is presented a two-step method to produce a binder-free porous germanium anode, depositing the semiconductor on metallic substrates by means of Plasma Enhanced Chemical Vapour Deposition (PECVD) and subsequently performing an electrochemical etching with hydrofluoric acid to create a porous structure.

The role of nanohybrid materials in the fields of polymer composites and electrochemical energy systems is significant since they affect the enhanced physical properties and improved electrochemical performance, respectively. As basic nanomaterials, carbon nanotubes and graphene were utilized due to their outstanding physical properties. With these materials, hybrid nanostructures were generated through a novel synthesis method, modified sol-gel process; namely, carbon nanotubes (CNTs)-maghemite and reduced graphene oxide (rGO)-maghemite nanohybrid materials were developed.

The aim of this work is to describe the influence of temperature on the structure and chemical composition of electrode materials for Li-ion accumulators. Theoretical part of this thesis contains described terminology and general issues of batteries and their division. Every kind of battery is provided with a closer description of a specific battery type. A separate chapter is dedicated to lithium cells, mainly Li-ion batteries. Considering various composition of Li-ion batteries, the next subchapters deeply analyzes the most used cathode (with an emphasis on the LiFePO4, LiMn1/3Ni1/3Co1/3O2)

This diploma thesis deals with the description of individual types of batteries. The first part is focused to primary and secondary batteries, materials for their positive and negative electrodes with a focus on lithium-ion batteries and their changes over time. The next section focuses on a more detailed description of sodium-ion batteries, used electrode materials and to their problems. Practical part is focesed to preparing of electrode materials and to completing of measuring electrochemical cell and to discribing of measuring methodes and to evaluation of measured data.

Cette thèse a pour sujet l'élaboration et la caractérisation d'anodes nano-architecturées pour des applications en microbatteries Li-ion 3D. Ces électrodes sont basées sur un collecteur de courant nano-structuré, constitué d'un tapis de nano-piliers de cuivre (Ø200nm, L=2µm) alignés verticalement. L'objectif de ce travail a été de montrer les avantages d'une électrode tridimensionnelle en revêtant ce substrat avec différents matériaux actifs en utilisant différentes techniques. De l'étain métallique Sn a pu être déposé par voie électrochimique et forme une couche conforme sur la nanostructure

碩士<br>國立中央大學<br>化學工程與材料工程學系<br>103<br>Lithium-ion batteries (LIBs) are the most widely used rechargeable batteries for powering electronic devices such as electric vehicles (EV), laptop computers and cellular phones due to their high energy density. We proposed to use ternary Sn-Sb-S metal sulfide as the active materials for LIBs. Specifically, Sn(1)-Sb(2)-S(4) and Sn(3)-Sb(2)-S(6) were first prepared and tested as anode. It is expected that the stepwise lithium insertion mechanism can alleviate volume changes and improve the mechanical stability of the electrode. In this study, the Sn(1)-Sb(2
