2019 Innovation & Patent Review: Lithium-ion Battery High Energy Anode - Silicon Suboxides & Si-C Composites Allow for Increased Li-ion Battery Energy Density

/EIN News/ -- Dublin, Nov. 29, 2019 (GLOBE NEWSWIRE) -- The "Lithium-Ion Battery High Energy Anode Innovation & Patent Review" 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.

Scope

  • 255,769 battery patent documents published across the globe between January 2017 and April 2019 have been screened using a machine learning approach (commercial relevance in the context of Li-ion battery anodes).
  • The resulting ranking includes 296 companies.
  • Patent portfolios by 34 key companies are discussed in detail and have been assembled into 17 decision trees that illustrate 106 different technical choices made by high energy material and Li-ion battery manufacturers.
  • 3-5 key patents by another 51 companies are listed.

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.
