Electrochemical characteristics of carbonaceous materials originated from C60 as an anode material for lithium secondary batteries |
| 초록 |
Fullerenes are well-known part of carbon allotropes, which are family of caged molecules. The highly interesting physical properties of fullerene have led to possibility of using units in formation of polymerized C60 which can be used as an active constituent of the electrode material in lithium secondary batteries application. Fullerene used to be employed as a passivation layer when deposited on the silicon of thin oxide thin film electrode. It has been reported that fullerene stabilize the interfacial properties of silicon thin film and thus improves the cyclability. However, the use of fullerene solely as an active anode material is still remained unclear. It has been reported that lithium can be electrochemically reacted with both C60 and C70 although it was limited to only cyclic voltammetry observation. Herein, we show the study of electrochemical performance of C60 as a sole active anode material for lithium secondary battery application. C60 was deposited on Cu foil by plasma enhanced thermal evaporation deposition process. The electrochemical performance of C60 anode materials are affected by process parameters such as plasma power, C60 film thickness, and the current density. |
