In the current roadmap on emerging battery technologies, LiMPO4 cathodes
raises high hope concerning the possibility of efficient energy storage at high
charge and discharge rate, thus raising the technical potential of hybrid and
plug-in hybrid electric vehicles as well as wind and solar energy storage.
Moreover, because of the safety issues raised by Li-ion batteries, LiMPO4
cathodes are of crucial interest for battery manufacturers.
In the 2011 report we noticed key acquisitions to complete technology portfolio
(Phostech by Süd Chemie, Süd Chemie by Clariant, High Power Lithium by Dow
Chemical and CIBA by BASF), 2012 is the year of finalisation of licensing deals
and the setting up of JV for a high scale manufacturing phase. The importance
in number of LiMPO4 manufacturing patents confirms the current increase of
production phase and also the increasing difficulties to protect innovative
LiMPO4 chemistry in the field.
The 2012 version of LiMPO4 patent landscape details the emergence (and
strong recent implication) of several new players (IRICO, BASF, ALEEES,University of Tsinghua) as well as the strengthening of companies in the field
(Toyota, GS Yuasa). With a total of 2900 patents analysed, this 2012 version
has several segmentation that helps you navigate through the landscape:
- The coverage of LiMPO4 in the cell (Manufacturing, Material…)
- The use of LiMPO4 within the cathode (Only LiMPO4, Mixture or coating other active material…)
- The type of claimed material (LiFePO4, LiFe1-xMnxPO4, LiNiPO4…)
- The type of carbon form factor (CNT, nanoparticle, nanofiber…)
- The type of claimed partial substitution of Li, P or O
In a sector where more than 2900 patents and patent applications have
been filed, this « Lithium Metal Phosphate batteries - Patent mapping » provides
you with a comprehensive panorama of the intellectual property landscape and
helps you:
- Position your company’s R&D and IP Portfolio notably regarding to the University of Texas patent
portfolio
- Identify key inventors and key players involved in specific compositions of cathode
- Understand the collaboration networks and theirs dynamics
