高容量非晶型碳材開發之研究

Development on High Capacity Amorphous Carbon

摘要


非晶型碳材的主要特性為在高C-rate(>5C)下,能達到80%以上快速充放電之負極碳材。主要的技術關鍵,在於起始原料的組成特性、結焦碳化製備及高溫重組碳化技術,在這些特性與技術的相互關聯下,開發合適的負極材料。此研究採用(1)不同油料篩選;(2)製程調控兩種方式,了解碳材結構變化與電池性能之影響;選用中油不同煉油製程中所提供的低價油料,製備更多選擇性與多樣性的前驅物;再經過結焦、碳化、修飾製程調控,以探討高容量非晶型碳材的電池性能。

The key feature of amorphous carbon as the anode material is that even at high C-rate (>5C) the capacity can achieve more than 80% under quick charge/discharge rate. The compositions of crude oils, coking processes and the carbonization of high-temp recombination are the main factors to achieve this. China Petroleum Company (CPC) is developing amorphous carbon as the anode material. The effects of different precursor oils and process parameters on the change of carbon structure and on the battery performance are discussed in this study. The use of oils from different refining processes in CPC was to make more selective and various precursors. Those precursors were introduced into fabrication processes of coking, carbonization, and modification to study the battery performances of the high capacity amorphous carbon.
