Zusammenfassung: | The present invention relates to a pre-lithiation apparatus, comprising: a pre-lithiation reaction tank in which an electrolyte is accommodated; a cathode that is wound in a roll shape outside the electrolyte, and is wound around a roll to travel inside the electrolyte; at least one lithium metal counter electrode disposed in the electrolyte and disposed so as to face the cathode traveling in the electrolyte in a state of being spaced at a predetermined interval; a charging/discharging unit connected in circuit to the cathode and the lithium metal counter electrode; and a constant-temperature tank for circulating the electrolyte in communication with the pre-lithiation reaction tank. The electrolyte contained in the pre-lithiation reaction tank is maintained at a constant temperature, concentration, and purity while being circulated between the pre-lithiation reaction tank and the constant-temperature tank for circulating the electrolyte. Uniform pre-lithiation of the cathode is possible in the pre-lithiation process.
본 발명은 전리튬화 장치에 관한 것으로, 내부에 전해액이 수용되는 전리튬화 반응조; 전해액 외부에서 롤 형태로 권취되어 있으며, 상기 롤에서 권취되어 전해액 내부를 주행하는 음극; 전해액 내에 배치되되, 전해액 내에서 주행하는 음극과 소정 간격 이격된 상태로 대면하도록 배치되는 적어도 한 개의 리튬 금속 대극; 음극 및 리튬 금속 대극에 회로적으로 연결되는 충방전부; 및 전리튬화 반응조와 연통된 전해액 순환용 항온 수조; 를 포함하며, 상기 전리튬화 반응조 내에 수용된 전해액은, 전리튬화 반응조와 전해액 순환용 항온 수조 사이에서 순환하면서 일정한 온도, 농도 및 순도로 유지된다. |
