Provided is a positive electrode for a lithium secondary battery, the positive electrode including a positive electrode mixture layer on a positive electrode current collector, wherein the positive electrode mixture layer includes a positive electrode active material and a lithium ion additive, the lithium ion additive is a lithium ion conductive ceramic material represented by Formula 1 below, and the lithium ion conductive ceramic material has a structure in which lithium ions are additionally inserted into vacancy sites of a NASICON-type (Na super ionic conductors-type) structure.LiMM(PO)&#x2003;&#x2003;[Formula 1] In Formula 1, Mis at least one of Ti and Ge, Mis one or more selected from the group consisting Al, Cr, Ga, Fe, Sn, In, Lu, Y, and La, and 0&#x3c;x1&#x2264;0.3, and 1.7&#x2264;y1&#x2264;2.0.

Positive electrode for lithium secondary battery, preparation method thereof, and lithium secondary battery including same

Disclosed is a method of manufacturing a solid electrolyte using water as a solvent. The method includes dissolving a precursor in water to form a slurry, drying the slurry to form granules, pressing the granules to form a pressed solid body, and sintering the pressed solid body to manufacture a solid electrolyte.

Method of manufacturing solid electrolyte

The present invention relates to a multilayer electrolyte cell, a secondary battery including the multilayer electrolyte cell, and a manufacturing method thereof, and more particularly, to a multilayer electrolyte cell, in which electrolytes are configured in multiple layers by stacking polymer coating layers containing ceramic solid electrolytes and liquid electrolytes including an ionic liquid in a porous structure base, a secondary battery including the multilayer electrolyte cell, and a manufacturing method thereof.

Multilayer electrolyte cell, secondary battery comprising multilayer electrolyte cell and manufacturing method therefor

Disclosed herein is an anode for a secondary battery manufactured thereby. The anode for a secondary battery includes a first adhesive member and a second adhesive member to which a plurality of electrolytes are fused, a first case configured to be fused to the first adhesive member, and a second case configured to be fused to the second adhesive member and the first case and into which an anode active material and a liquid electrolyte are injected. The anode has an effect of maximizing a reaction area because an electrolyte is exposed at both surfaces of the anode for a secondary battery.

Manufacturing method of anode for secondary battery and anode for secondary battery manufactured thereby

Disclosed herein are a manufacturing method of an anode for a secondary battery and an anode for a secondary battery manufactured thereby. The manufacturing method of an anode for a secondary battery includes firstly fusing a plurality of electrolytes to a first adhesive member and a second adhesive member, secondly fusing the first adhesive member and the second adhesive member to a first case and a second case, respectively, injecting an anode active material and a liquid electrolyte into the second case to which the second adhesive member is fused, and thirdly fusing the first case and the second case to each other. The anode for a secondary battery has an effect of maximizing a reaction area because an electrolyte is exposed at both surfaces of the anode for a secondary battery.
