| Abstract |
: |
Electrochemical reactions occurring at a graphite electrode were investigated to gain insight into the effects of film-forming additives such as vinylene carbonate, fluoroethlyene carbonate (FEC) and lithium bis(oxalato) borate (LiBOB) on surface film formation on the electrode. The surface film generated in the presence of a mixture of FEC and LiBOB was found to have the certain characteristics that are important in the initial charging and discharging process. The mixture produced a highly resistive film on the graphite electrode, resulting in an improvement in Coulombic efficiency. |
