Lithium-Ion Battery Innovation & Patent Review 2019: Focus on Positive Electrode - Patent Filings Between January 2017 and January 2019

/EIN News/ -- Dublin, April 25, 2019 (GLOBE NEWSWIRE) -- The "Lithium-Ion Battery Innovation & Patent Review - Positive Electrode" report has been added to's offering.

Unique insights from a machine learning-supported patent analysis have been combined with a review of the emerging Li-ion battery high energy cathode supply chain. NCA (nickel-cobalt-aluminium) and NMC (nickel-manganese-cobalt) are identified as the key material types on which most patenting activity is focused.

The NCA supply chain is characterized by close collaboration between few players, while the NMC supply chain involves many players with more fluid relationships. Cobalt-free materials are discussed as well as longer-term options for cathode materials that will be used in solid-state batteries.


Patent filings between January 2017 and January 2019, current supply chain relationships and the direction of R&D efforts are discussed for 29 companies. Key patents are listed for an additional 130 companies. The current NMC and NCA supply chains are plotted with relationships between key players.

Reasons to Buy

The reader will understand which R&D topics are of highest interest to the industry, and how the high energy cathode supply chain will evolve in the coming years in the context of two possible scenarios.

Key Highlights

It is illustrated how key cathode material producers are shifting their R&D activities from NMC to NCA because cobalt can be reduced more effectively. At the same time, several major Li-ion battery and automotive manufacturers remain very much focused on NMC because switching costs to NCA are high.
