IP Overview presents a patent mapping analysis of the “LTO electrodes for Li-ion batteries” field.
In the current roadmap on emerging battery technologies, Lithium Titanate (LTO) raises high hope concerning the possibility of high rate capability, fast charge, wide operating temperature range and long life cycle. Its lower operating voltage that can be considered as a handicap also brings a significant advantage in terms of safety. The LTO anodes are therefore of crucial interest for battery manufacturers and end-users of batteries.
This interest results in a very high research and patenting activity in the last five years. With the near expiry of the historical patents (like the US5545468 Panasonic patent in 2013), many actors are building up their portfolio in order to acquire a blocking position.
The present report analyses the patent environment and notably highlights the strategy of current major players. These major players are end-users (Toshiba, Panasonic-Sanyo, Toyota, ...), battery manufacturers (GS Yuasa, Enerdel, Altairnano...), material manufacturers (Ishihara Sangyo Kaisha, LG Chemical, ATL, Titan Kogyo, Toho Titanium... ) and institutional entities (University of Tsinghua, CEA, Argonne National Laboratory, Chinese Academy of Science (CAS), Central South University).
In a sector where 960 patents and patent applications have been filed, this «IP Overview - LTO Electrodes for Li-ion Batteries» also focuses on the emergence of Korean (Samsung SDI), Japanese (Murata Manufacturing), Taiwanese (Hon Hai Prec), European (Süd Chemie) and Chinese manufacturers (ATL, McNair Technology and Liyuan Power Group) and provides you with a comprehensive panorama of the intellectual property landscape and helps you:
Evolution of patent filings (1981-2011)
An initial phase of filings occurred in the early 1990's. Between 1996 and 2003, key patents were filed and players started constituting their portfolios. As of 2004, a strong increase in filings can be observed to reach around 200 patent applications in 2010.
