Lithium-Ion Battery High Energy Anode: Global Innovation & Patent Review Report 2019

/EIN News/ -- Dublin, July 10, 2019 (GLOBE NEWSWIRE) -- The "Lithium-Ion Battery High Energy Anode: Global Innovation & Patent Review Report 2019" report has been added to ResearchAndMarkets.com's offering.

This review discusses options that are evaluated by key lithium-ion industry players to synthesize high energy negative electrode materials and corresponding electrodes, according to a machine learning-supported analysis of global patent filings.

Reasons to Buy

Comprehension of the high energy negative electrode decision tree allows for the identification of promising future R&D directions that have not yet been explored.

The review supports battery makers and automotive players in defining their roadmap, i. e. which anode materials can be used for mass applications at which energy density and with which timeline.

Key Highlights

The review highlights how innovation leaders combine many different process steps to obtain high performing materials and batteries. Many other players can learn based on this review which crucial parts of the innovation puzzle they have been considering to an insufficient extent thus far.

The authors of this review have prior hands-on' R&D and commercial experience in the Li-ion battery materials industry.
