==COATED CATHODE ACTIVE MATERIAL, METHOD OF PREPARING THE SAME, AND CATHODE AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY EACH INCLUDING THE SAME - A simplified explanation of the abstract==


This abstract first appeared for US patent application 17856016 titled 'COATED CATHODE ACTIVE MATERIAL, METHOD OF PREPARING THE SAME, AND CATHODE AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY EACH INCLUDING THE SAME

==Simplified Explanation==

The patent application describes a coated cathode active material for use in non-aqueous electrolyte secondary batteries. The coated cathode active material includes a cathode active material particle and a coating layer on its surface, which consists of LiAlF, LiF, and LiAlF.

* The coated cathode active material is used in non-aqueous electrolyte secondary batteries.
* The coating layer on the cathode active material particle includes LiAlF, LiF, and LiAlF.
* The coated cathode active material improves the performance and efficiency of the battery.
* The method of preparing the coated cathode active material is also described in the patent application.

== Potential Applications ==
The technology described in this patent application has potential applications in the field of non-aqueous electrolyte secondary batteries. It can be used in various devices and applications that rely on such batteries, including:

* Electric vehicles
* Portable electronic devices (e.g., smartphones, tablets)
* Energy storage systems
* Power tools

== Problems Solved ==
The technology solves several problems associated with non-aqueous electrolyte secondary batteries, including:

* Low energy density: The coated cathode active material improves the energy density of the battery, allowing for longer-lasting and more powerful battery performance.
* Limited cycle life: The coating layer on the cathode active material particle helps to prevent degradation and extend the cycle life of the battery.
* Safety concerns: The use of LiAlF and LiF in the coating layer enhances the safety of the battery by reducing the risk of thermal runaway and other safety hazards.

== Benefits ==
The technology offers several benefits for non-aqueous electrolyte secondary batteries:

* Improved performance: The coated cathode active material enhances the overall performance of the battery, including higher energy density, improved cycle life, and better stability.
* Extended battery life: The coating layer on the cathode active material particle helps to prevent degradation, resulting in a longer-lasting battery.
* Enhanced safety: The use of LiAlF and LiF in the coating layer improves the safety of the battery by reducing the risk of thermal runaway and other safety hazards.
