Patent filings on LFP cathode materials on the rise

LFP (Lithium Iron Phosphate) is drawing high attention as a LIB cathode material to replace expensive LCO. LFP has excellent structural stability due to its olivine structure. Thus, it ensures a high level of safety when used in secondary batteries. In addition, there are on-going efforts to develop energy density. First of all, its biggest advantage is low prices. The LIB industry makes investments in manufacturing facilities and product development in anticipation of future growth of the LFP market.

LFP was invented by Prof. John B. Goodenough at the University of Texas. He has the rights for two original LFP patents and keeps filing numerous applied patents, conducting constant research efforts for commercialization. Besides, some companies in Canada and Europe have made constant efforts for R&D on commercialization of LFP.

Meanwhile, CNRS, Hydro-Quebec, and the University of Texas holding the rights for original LFP technologies have established a specialized patent licensing company, LiFePO4+C Licensing AG, to prepare global licensing.

In this context, SNE provides analysis of key patents on LFP cathode materials used in LIBs. The patent information provided in this key patent analysis report covers technological backgrounds and data regarding management and patent rights. These patent data are to be a good help to attain prior art data or related problems, technological progress, and other useful information for exploring novel ideas and solutions for possible problems. It can also serve as a useful tool to prevent or prepare future patent disputes in advance through investigation of third-part patent rights.

This report analyzes patents on LFP cathode materials that have been filed in Korea, the U.S., Japan, and Europe until March, 2013. For this, among 3,976 patents, 1096 cases are selected as valid patents. This is expected to be a great help to examine the patent trend and related key patents in the field of LFP cathode materials.

This LFP cathode material patent analysis report provides analysis on selected key patents on LFP cathode materials including key patent analysis, technology development charts, and key patent summaries. Especially, it provides patent trends for each technology sector??Composition, Surface Structure, Particle Size Distribution, Manufacturing Technology, Metal Substitution, Manufacturing Process, and Structure.
