Emerging as a key issue in the current lithium secondary battery market

Among various attempts to improve performance of lithium secondary batteries, technologies to increase battery voltage are recently drawing attention. High voltage electrolytes are one of those necessary to achieve high voltage. Along with the key secondary battery technologies such as cathode and anode materials to store high capacity energy, one of the main concerns of the secondary battery industry is to develop high voltage electrolytes that can be charged at higher voltage than typical electrolytes.

To reflect this trend, SNE presents a key patent analysis report for high voltage electrolytes used in LiBs. This report provides information for related technologies, management, and rights. Using this patent information provides a comprehensive understanding of prior art, the problems thereof, and the progress in related technologies, and helps to find new ideas and solutions. Also, it can be a guideline to prevent patent infringements by examining the scope of third party patent rights.

In this report, 1,455 valid patents were selected and analyzed from 8,758 patents on high voltage electrolytes filed in Korea, the U.S., Japan, and Europe until December, 2012. This is expected to provide a useful overview of recent trends in patent applications on high voltage electrolytes and key patents.

This report provides an analysis of electrolyte technologies divided into five sectors: Organic Solvent Electrolyte, Polymer Solid Electrolyte, Inorganic Solid Electrolyte, Gel Electrolyte, and Ionic Liquid. In addition, it also devotes some pages to analyzing electrolyte additives for high voltages. Among them, the Sector Organic Solvent Electrolyte shows the most aggressive patenting filing.

Of Top 10 applicants of patents on high voltage electrolytes, Japanese companies account for the largest portion (7 companies) and three Korean companies are included. Especially, the Japanese companies, Ube Industries and Mitsubishi Chemical, have considerably many patents. What is noteworthy is that the patents filed by the automaker, Toyota, ranked 12th. Samsung SDI has also showed a steady patenting activity and LG Chem and Hitachi Maxwell are also increasing their patent filings.

The key patents analyzed in this report totaled 140 cases, of which 113 cases were filed in the United States. It is shown that most of the key patent filings were filed by a few leading companies in some countries. The country-specific analysis of the key patents also shows that the leading companies own most of the key patents.
