Abstract
Description / Summary
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:
- Position your company's R&D and IP Portfolio
- Identify key inventors and key players involved in specific compositions
of anodes
- Understand the collaboration networks and theirs dynamics
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.
