OLIVINE-BASED CATHODE MATERIALS WITH IMPROVED CONDUCTIVITY - A simplified explanation of the abstract

This abstract first appeared for US patent application 17824310 titled 'OLIVINE-BASED CATHODE MATERIALS WITH IMPROVED CONDUCTIVITY

Simplified Explanation

- The patent application is for an electrode active material that includes a dopant (M) and a lithium manganese iron phosphate host material represented as LiMMnFePO. - The dopant is a transition metal or main group metal. - The electrode active material has an increased ionic conductivity compared to a lithium manganese iron phosphate (LiMnFePO) without the dopant. - The value of x in the formula LiMMnFePO is between 0.01 and 0.15. - The value of y in the formula LiMMnFePO is between 0.30 and 0.85.

Original Abstract Submitted

An electrode active material includes a dopant (M) and a lithium manganese iron phosphate host material represented as LiMMnFePO, wherein the dopant is a transition metal or main group metal, and the electrode active material exhibits an increased ionic conductivity compared to a lithium manganese iron phosphate (LiMnFePO) without the dopant, wherein x is 0.01 to 0.15, and y is 0.30 to 0.85.
