Manufacturing method of carbon fiber sheet current collector for all solid state rechargeable thin film lithium secondary battery, and all solid state rechargeable thin film lithium secondary battery comprising carbon fiber sheet current collector

摘要

The present invention relates to a method for producing a carbon fiber sheet current collector for an all-solid-state lithium secondary battery, a cell for an all-solid-state lithium secondary battery including a carbon fiber sheet current collector, and an all-solid-state lithium secondary battery including the same. The method comprises the steps of: dispersing a carbon fiber in a solution; and drying the dispersed solution. The current collector can be produced through a simple method, and very excellent adhesion with a composite electrode can be maintained without using a binder.
