Cathode for a Lithium Secondary Battery Based on an Organic-Inorganic Active Composite, Method for Preparing the Same, and Lithium Secondary Battery Including the Same

Organic-Inorganic Active Composite-Based Lithium Battery Cathode Technology

This technology relates to a cathode structure for lithium secondary batteries that increases energy density and driving stability by combining organic and inorganic active materials.

Conventional single organic or single inorganic cathodes have had performance limitations in conductivity, binding strength, and internal resistance. This technology designs a composite cathode including a current collector, conductive material, organic-compound-based active material, and inorganic active material to improve interfacial binding force and charge-transfer characteristics.

As a result, it can lower internal electrode resistance and increase utilization of active components, thereby improving output characteristics, energy density, and cycle stability of lithium secondary batteries.

Key Features:

• It applies a cathode structure in which organic and inorganic active components are composited.
• It improves charge-transport pathways in the electrode by optimizing conductive and binding structures.
• It is advantageous for reducing internal resistance and securing driving stability by improving bonding between active components.
