| Summary: | 碩士 === 國立高雄第一科技大學 === 電機工程研究所碩士班 === 105 === Rechargeable lithium-ion batteries as the main power source, the portable electronic device, either or both of concern in the scientific industry. In order to make the lithium ion battery having the advantages of high capacity, high life and low cost, we use the reactive magnetron sputtering system to prepare the anode material of the excellent solid lithium-ion battery, and proceed to the commercial research direction.
In this report, multi–layer graphene (below ten layers) were prepared at low temperature, we could efficiently fabricate the graphene lower then ten layers under the following conditions: C2H2 flow with 3 sccm, process time of 60 seconds, annealing temperature at 700℃ and annealing time of 30 minutes, and which combined with tin oxide nano-particles under the following conditions: O2 flow with 8 sccm, annealing temperature at 800℃, annealing time of 60 minutes, and different process time of 30、60、120、240 seconds to be a tin oxide nano-particles/multi-layer graphene nanocomposites, it can be used as anode material for lithium-ion batteries, the excellent electrical properties of graphene and combined with tin oxide particles with nanostructures can reduce the effect of volume change during charging and discharging, so that the electrode is not easily broken, improve the cyclability and further extend the service life of lithium-ion batteries.
