Originální abstrakt

This paper is based on a research of negative materials for Lithium-ion accumulators. In the research are considered the methods, which would lead to enhance capacity of Lithium-ion accumulators along with improving their safety. In the first part of our research we prepared specific materials for negative electrode. These materials should be able to reduce or completely remove the irreversible capacity of Lithium-ion accumulators. Electrode materials were made by lithiation process with help of n-Butyllithium reagent. In this way prepared materials already contain the lithium ions (cations), where the Li+ intercalated to materials. For experimental purposes were chosen commonly uses graphite materials for negative electrodes of Lithium-ion accumulators as natural graphite or expanded graphite. The second part of this study is focused on safety testing of various mixtures (materials). These tests were performed on STA i1500 device, this device offers two analyses TG and DCS which are based on temperature changes of specimen.
