  "textContent": "A cathode active material for a lithium secondary battery includes a core component comprising a lithium transition metal oxide and a sulfurized coating layer to enhance lithium-ion conductivity and cycle life. The coating layer may include a sulfur component and may be structured with a dual-layer configuration, where a first layer of alkali metal oxide is applied on the core component and a second sulfurized layer is disposed on the first layer. Methods for manufacturing the cathode active material involve forming a coating layer using vapor deposition or heat-treating a mixture of the core component and sulfur precursors, creating a uniform, thin sulfurized layer. This structure mitigates side reactions with sulfide-based solid electrolytes, resulting in improved coulombic efficiency, rate performance, and stability.",
