POSITIVE ELECTRODE FOR LITHIUM-SULFUR BATTERY AND LITHIUM-SULFUR BATTERY COMPRISING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18025958 titled 'POSITIVE ELECTRODE FOR LITHIUM-SULFUR BATTERY AND LITHIUM-SULFUR BATTERY COMPRISING SAME

Simplified Explanation

The present disclosure is about a positive electrode for a lithium-sulfur battery and the battery itself.

  • The positive electrode is made up of two types of sulfur-carbon composites with different shapes and properties.
  • The electrode has low porosity and a uniform surface, which improves its electrochemical reactivity and stability.
  • This allows the positive electrode to maximize its capacity and enables the lithium-sulfur battery to have high capacity, high energy density, and a long lifetime.


Original Abstract Submitted

The present disclosure relates to a positive electrode for a lithium-sulfur battery comprising two kinds of sulfur-carbon composite including carbon materials having different shapes and properties as a positive electrode active material, and a lithium-sulfur battery comprising the same. The positive electrode for the lithium-sulfur battery according to the present disclosure exhibits low porosity and excellent surface uniformity to improve the electrochemical reactivity and stability of the positive electrode, thereby maximizing the expression of the capacity of the positive electrode, and thus enabling high capacity, high energy density, and long lifetime of the lithium-sulfur battery.
