Research and Markets has announced the addition of the “LIB Key Patent Analysis 2013: High-Voltage Electrolyte” report to their offering. Among various attempts to improve performance of lithium secondary batteries, technologies which increase battery voltage have emerged as a viable solution. High voltage electrolytes are 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, this report offers a key patent analysis 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 the industry, the problems thereof, and the progress in related technologies, and helps to find new ideas and solutions. It can also be used as 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 US, 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. The report also 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 covers an analysis of electrolyte additives for high voltages. Of these, the Sector Organic Solvent Electrolyte shows the most aggressive patenting filing.
