Method of preparing electrode composition having a carbon-containing-coated metal oxide, electrode composition and electrochemical cell |
摘要 |
Provided is a novel method of forming an electrode composition suitable for use in an electrochemical cell. The method involves (a) forming a carbon-containing coating on a metal-oxide material; and (b) forming an electrode paste or slurry from components comprising a solvent, a polymeric binder material and the coated metal-oxide material. Also provided is an electrode composition suitable for use in an electrochemical cell. The electrode composition includes a polymeric binder material and an active material. The active material includes a metal oxide with a carbon-containing coating thereon. Also provided is an electrochemical cell which includes an electrode formed from the electrode composition. The invention results in an electrochemical cell having improved charge-discharge cycle life and improved coulomb efficiency.
