SYSTEM FOR PREPARING ELECTRODE HAVING HIGH CYCLE EFFICIENCY, METHOD FOR PREPARING ELECTRODE HAVING HIGH CYCLE EFFICIENCY, AND APPLICATION THEREOF

摘要

A system for preparing an electrode having high cycle efficiency, a method for preparing an electrode having high cycle efficiency, and application thereof. The system comprises an electrode treatment unit; a temperature control treatment device (20a) connected in series to the electrode treatment unit, the temperature control treatment device (20a) comprising a temperature control vacuum treatment device (201) or a temperature control inert treatment device (202); and a lift-off unit connected in series to the temperature control treatment device (20a). Or the system comprises an atmosphere box (20b), the interior of the atmosphere box (20b) being vacuum, or an inert atmosphere and/or a protective atmosphere; and the electrode treatment unit provided inside the atmosphere box (20b), the temperature control box (9) connected in series to the electrode treatment unit, and the lift-off unit connected in series to the temperature control box (9). The electrode treatment unit comprises a first metal source unwinding shaft (1); a metal electrode unwinding shaft (2) to be supplemented connected in parallel to the first metal source unwinding shaft (1); and a compression roller device connected in series to the first metal source unwinding shaft (1) and the metal electrode unwinding shaft (2) to be supplemented. The system is simple, and an electrode prepared by the system has high first cycle efficiency and good cyclicity. A total battery manufactured by the electrode has high first cycle efficiency and a high capacity retention ratio.
