CATHODE ACTIVE MATERIAL FOR ALL-SOLID-STATE BATTERY WITH CONTROLLED PARTICLE SIZE AND PREPARATION METHOD THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 18312368 titled 'CATHODE ACTIVE MATERIAL FOR ALL-SOLID-STATE BATTERY WITH CONTROLLED PARTICLE SIZE AND PREPARATION METHOD THEREOF

Simplified Explanation

The present disclosure relates to a cathode active material for an all-solid-state battery with a controlled particle size and a method for preparing the same. In particular, the cathode active material includes lithium and a transition metal, wherein the cathode active material has a single peak in the range of 1 μm to 10 μm as a result of particle size distribution (PSD) analysis.

• Explanation:

- Cathode active material for all-solid-state battery - Controlled particle size - Includes lithium and transition metal - Single peak in particle size distribution analysis

• • Potential Applications:

- All-solid-state batteries - Energy storage systems - Electric vehicles - Portable electronics

• • Problems Solved:

- Enhanced battery performance - Improved energy density - Controlled particle size distribution

• • Benefits:

- Increased battery efficiency - Longer battery life - Enhanced safety features

• • Potential Commercial Applications:
