Study of Electrode Materials for Sodium-ion Batteries
Jilčík, Jan ; Bača, Petr (referee) ; Libich, Jiří (advisor)
This bachelor thesis deals with the issue of electrochemical cells, more precisely sodiumion batteries. Part of the work is the introduction and comparison of lithium-ion battery technology with the new sodium-ion battery technology. Sodium-ion batteries represent one of the new and very promising types of batteries that belong to the so-called post lithium system group. As part of the bachelor thesis, the issue of negative (anode) materials for sodium-ion batteries is described and discussed in detail. The work mentions silicon as a promising electrode material for the negative electrode of sodium-ion batteries. The practical part of the bachelor's thesis is focused on doping the anode of a sodium-ion battery with silicon and its electrochemical properties are investigated.

Electrode Materials for Sodium-ion Batteries Based on Carbon
Homolka, Tomáš ; Binar, Tomáš (referee) ; Libich, Jiří (advisor)
This diploma thesis focuses on electrode materials for sodium batteries with a particular emphasis on anodes, especially hard carbon. The history of sodium-ion batteries and their operating principle are discussed as well. The project also describes the history of lithium ion batteries, as they share a significant part of their development and operating principle with sodium-ion batteries. In the practical part, measurements of rate capability, capacity and coulombic efficiency of the selected hard carbon are then performed. The sodation method is also tested and the effect of moisture on its properties is further investigated.

Use Of Reduced Graphene Oxide In Lithium- And
Sodium-Ion Accumulators
Balcárková, Lucie
Graphene oxide (GO) or reduced graphene oxide (rGO) belongs among artificially, manmade substances. The graphene oxide has got many possible uses and varienty of applications thanks to its specific properties. It is usable in the field of nanoaplications for its catalytic properties as well as in supercapacitors and electrochemical energy sources. This article expores and describes the use of graphene oxide as an active electode material in lithium and sodium-ion batteries.
