摘要: 
本研究將銅箔代替傳統的金屬鋰製備LiMn2O4/LiClO4/Cu薄膜鋰離子電池。利用XRD、FESEM、XPS 與CV及充放電測試分析特性研究。FESEM觀察顯示LiMn2O4薄膜呈現均勻之表面型態。XPS分析顯示第一圈充電銅箔含有8.3%的鋰。半電池經循環伏安(CV)測試,氧化電位為2.59、2.85、3.34與3.60V,還原電位為3.15、2.15和1.21V。充放電測試顯示電流密度為10μA/cm2第1圈電容量為40 mAh/g充放電20圈後電容量僅剩17 mAh/g。相較於鋰金屬,銅電極會與LiClO4電解質作用形成CuO (Cu+ClO4→CuO+ClO3 )。在充電過程中又將其還原成銅而本身部分形成Li2O (CuO+2Li++2e-→Cu+Li2O )而喪失部分之電容量,選擇某種不與LiClO4產生氧化反應的金屬電極可能可以改善電容量。

Using copper (Cu) substitute for replacing conventional metallic Li, thin-film lithium-ion batteries LiMn2O4/LiClO4/Cu were prepared of. They were further characterized by X-ray diffraction (XRD), FE-SEM, X-ray photoelectron spectroscopy (XPS), cyclic voltammetry (CV) and charge-discharge cyclic tests. The LiMn2O4 film surface morphology was uniform by FESEM observations. XPS analysis showed that lithium content on the copper foil the first cycle charging was 8.3%. The CV measurement showed oxidation peaks at 2.59, 2.85, 3.34 and 3.60 V, and reduction peaks at 3.15, 2.15 and 1.21 V. The first discharge capacity was 40mAh/g and degraded to 17mAh/g at 20th cycle at current density 10μA/cm2. Compared with Li metal anode, Cu was oxidized into CuO by LiClO4 strong oxidizer (Cu+ClO4→CuO+ClO3 ). During the charging, the reduction of Li+ was partially replaced by the reduction of Cu (CuO+2Li++2e-→Cu+Li2O ), therefore, resulting in the loss of capacity. Selecting a metal anode which will not be oxidized by the electrolyte could improve the reversible capacity.
