Method for Manufacturing Positive Electrode for Lithium Secondary Battery and Positive Electrode for Lithium Secondary Battery Manufactured Thereby - A simplified explanation of the abstract

This abstract first appeared for US patent application 18032437 titled 'Method for Manufacturing Positive Electrode for Lithium Secondary Battery and Positive Electrode for Lithium Secondary Battery Manufactured Thereby

Simplified Explanation

The patent application describes a method for manufacturing a positive electrode for a lithium secondary battery. Here are the key points:

  • The method involves mixing a lithium transition metal oxide and a carbon-based material with a low density in a mechanofusion manner. This forms a positive electrode active material with a carbon coating layer.
  • The positive electrode active material is then dry mixed with a binder to create a dry mixture.
  • The dry mixture is applied onto a positive electrode current collector.
  • The resulting positive electrode is suitable for use in a lithium secondary battery.


Original Abstract Submitted

A method for manufacturing a positive electrode for a lithium secondary battery includes i) mixing a lithium transition metal oxide and a carbon-based material having a density of 0.05 g/cc or less in a mechanofusion manner to form a positive electrode active material including a carbon coating layer, ii) dry mixing the positive electrode active material and a binder to form a dry mixture, and iii) applying the dry mixture on a positive electrode current collector. A positive electrode for a lithium secondary battery manufactured by the method is also provided.
