- 摘要
- 近期鋰離子電池(lithium-ion batteries, LIBs)的新穎矽碳複合負極，藉由結合矽的超高容量，以 及碳的高機械強度和優異導電特質，矽碳複合負極有機會應用於下一代LIBs。因鋰離子嵌入/脫嵌 於矽碳負極內部，產生材料體積膨脹/收縮應力，使負極生成嚴重裂縫進而破碎，影響電子傳遞， 造成克電容量減少與增加材料阻抗。此外，破碎的矽材料與電解液反應，導致固體電解液界面膜 (solid electrolyte interphase, SEI)不斷的增生，SEI膜的成長與材料阻抗提高，影響電池循環壽命。本 文回顧近期有關Si/C複合負極的創新增強策略，討論主題含電池反應機制、結構設計原理、材料合 成方法及形態、與電化學特性，並介紹其他外部影響因子，提升Si/C複合負極與鋰離子電池性能， 如預鋰化技術、電解液添加劑與黏著劑，旨在提供完整Si/C複合負極的相關技術資訊，利於理解與 設計矽基負極應用於LIBs。

- The recent trend in lithium ion batteries (LIBs) has progressively developed to apply the novel silicon/ carbon composite anode, which combines high lithiation capacity of silicon and excellent mechanical and conductive properties of carbon. The silicon/carbon composite anode enables the most promising applications for next generation LIBs. Because lithium ions are inserted/de intercalated inside the silicon carbon negative electrode, the volume expansion/shrinkage stress is generated, causing serious cracks in the negative electrode, and thus affecting the electron transfer, and finally reducing the specific capacity and increasing the impedance. Moreover, the cracked silicon materials react with the electrolyte to cause solid electrolyte interphase (SEI) to continuously proliferate. The SEI growth and resistance increase affect the battery cycle life. This article reviews the recent innovative technologies about performance enhancement of the Si/C composite anodes. There are many discussion topics, including the battery reaction mechanisms, structural design principles, material synthesis methods, morphological and electrochemical characteristics of Si/C composite anodes. The other factors about the improvement of capability of Si/C composite anodes and lithium ion batteries, such as prelithiation treatment, electrolyte additives and polymeric binders, are also discussed here. The relevant technical information of Si/C composite anodes is aimed to help understanding and designing of silicon based anodes in LIBs.
