Anode Active Material for Lithium Secondary Battery and Lithium Secondary Battery Including the Same - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240021799 titled 'Anode Active Material for Lithium Secondary Battery and Lithium Secondary Battery Including the Same
Simplified Explanation
The abstract describes a patent application for an anode active material for a secondary battery. The material consists of composite particles that contain carbon-based particles with pores. These pores are either filled with a silicon-containing coating layer or the coating layer is formed on the surface of the carbon-based particles. A surface oxide layer, containing silicon oxide, is then formed on the silicon-containing coating layer. The composite particle has a predefined silicon oxidation number ratio.
- The patent application describes a new anode active material for secondary batteries.
- The material is composed of composite particles containing carbon-based particles with pores.
- A silicon-containing coating layer is formed inside the pores or on the surface of the carbon-based particles.
- A surface oxide layer, containing silicon oxide, is formed on the silicon-containing coating layer.
- The composite particle has a predefined silicon oxidation number ratio.
Potential Applications:
- This technology can be used in secondary batteries, such as lithium-ion batteries, to improve their performance and energy storage capacity.
Problems Solved:
- The use of carbon-based particles with silicon-containing coating layers helps to address the issue of low energy storage capacity in secondary batteries.
- The predefined silicon oxidation number ratio ensures stability and efficiency of the anode active material.
Benefits:
