MANUFACTURING METHOD FOR LONG-LIVED NEGATIVE ELECTRODE AND CAPACITOR BATTERY ADOPTING THE SAME

A manufacturing method for a long-lived negative electrode and an organic hybrid type supercapacitor battery adopting the same. The manufacturing method for the negative electrode includes the following steps: mixing materials, which includes mixing a lithium fast storage carbon and a binder (3) with a solvent; pressing, which includes pressing the mixture into a sheet plate with a certain thickness by a roller press; coating, which includes preparing a slurry with a conductive agent (1) and coating the slurry onto a negative current collector (2); attaching, which includes attaching the sheet plate onto the negative current collector (2) coated with a layer of conductive agent (1) by pressing; preparing the negative electrode by drying, pressing, cutting and vacuum drying. With the process of preparing the sheet plate by pressing before attaching it onto the current collector, the negative electrode has a higher compaction density and cycle life. The manufactured organic hybrid type supercapacitor battery has characteristics with high energy density (up to 45-80Wh/Kg) and high power density (> 4500 W/Kg), and it can be widely used in electric vehicles, power tools, solar energy storage, wind energy storage, portable appliances and other fields.
