Abstract
Provided is an anode for a lithium secondary battery capable of improving the performance and the life of a lithium air battery by forming the anode so that lithium metal is sealed, but migration of lithium ions is possible, and thus, preventing corrosion of a lithium metal and the generation of hydrogen gas caused by permeation of moisture and oxygen gas into the anode, a manufacturing method thereof, and a lithium air battery containing the same.
Claims13
An anode for a lithium secondary battery comprising:
- a current collector;
- a lithium metal laminated on the current collector;
- a separator containing an electrolyte laminated on the lithium metal;
- a solid electrolyte laminated on the separator;
- and
- a sealing part sealing a circumferential side of a laminate in which the current collector, the lithium metal, the separator and the solid electrolyte are laminated.
A manufacturing method of the anode for a lithium secondary battery comprising:
- laminating a current collector, a lithium metal, a separator containing an electrolyte and a solid electrolyte in turn to form a laminate;
- pressing the laminate in a laminated direction;
- forming a sealing part on a circumferential side of the laminate;
- and
- removing the pressed pressure after the sealing part is formed.
A manufacturing method of the anode for a lithium secondary battery comprising:
- laminating a lithium metal, a separator containing an electrolyte, and a solid electrolyte in turn on the inside of a current collector having an empty inside and open one side;
- pressing a laminate in a laminated direction on a lower side of the current collector and on an upper side of the solid electrolyte;
- forming a sealing part on a contact surface between the current collector and the solid electrolyte;
- and
- removing the pressed pressure after the sealing part is formed.
