Positive Electrode and Lithium Secondary Battery Manufactured Using Same - A simplified explanation of the abstract

This abstract first appeared for US patent application 18287966 titled 'Positive Electrode and Lithium Secondary Battery Manufactured Using Same

The abstract describes a positive electrode for a battery, which includes two types of lithium iron phosphate materials with different particle sizes and characteristics.

• The positive electrode active material layer contains a first lithium iron phosphate and a second lithium iron phosphate.
• The first lithium iron phosphate has a larger average particle diameter than the second lithium iron phosphate and at least one facet.
• When observed with a scanning electron microscope, the cross-section of the positive electrode shows that the first lithium iron phosphate has at least one side with a length of 2 μm or more.

Potential Applications: - This technology can be used in lithium-ion batteries for various applications such as electric vehicles, portable electronics, and energy storage systems.

Problems Solved: - Provides improved performance and efficiency in lithium-ion batteries. - Enhances the overall energy density and cycle life of the batteries.

Benefits: - Increased energy storage capacity. - Longer battery lifespan. - Enhanced overall battery performance.

Commercial Applications: - This technology can be utilized by battery manufacturers to produce high-performance lithium-ion batteries for consumer electronics, electric vehicles, and renewable energy storage systems.

Questions about the technology: 1. How does the use of two different lithium iron phosphate materials improve the performance of the positive electrode in a battery? 2. What are the specific advantages of having a larger average particle diameter in the first lithium iron phosphate material compared to the second material?

Original Abstract Submitted

A positive electrode includes a positive electrode active material layer, and the positive electrode active material layer includes a first lithium iron phosphate and a second lithium iron phosphate as a positive electrode active material, the first lithium iron phosphate has an average particle diameter Dgrater than that of the second lithium iron phosphate and at least one facet, and when the cross section of the positive electrode is observed with a scanning electron microscope (SEM), the cross section of the first lithium iron phosphate has at least one side having a length of 2 μm or more.
