| Abstract: | The electrochemical behavior of graphite electrode based on water binder and PVDF were investigated. Cycling voltammetry, galvanostatic charge-discharge techniques and SEM was used for analysis of the electrode after cycling. The results show that the type of binder influences specific capacity, rate capability, coulomb efficient and cycling performances of the graphite electrode. |
