  • Seeo
  • MORE

This review discusses technical options that are pursued by key commercial lithium-ion battery players to build solid-state Li-ion batteries for an increasing number of applications (IoT, medical devices, consumer electronics, electric vehicles/trains, stationary applications). A machine learning supported screening of the global patent literature for commercial relevance provides the basis for unique insights, which have been condensed into an ‘innovation decision tree’ and a gap analysis (liquid vs. solid electrolyte Li-ion batteries).

Scope

  • This review is based on a machine learning supported screening of 260,004 patent documents.
  • 23 decision tree diagrams illustrate how R&D players have made a variety of choices as to which concepts, materials, processes, architectures to pursue.
  • The review includes a discussion of 11 current and 24 prospective solid-state lithium-ion battery suppliers, as well as of 6 materials & technology suppliers.
  • Key solid-state battery patent families by 38 additional companies are listed with links to the full text.

Reasons to Buy

Innovation decision tree diagrams allow for a comprehensive understanding as to how R&D decisions diverge or are similar between different protagonists. By understanding the weaknesses and strengths of different innovators, unique R&D programs can be defined that study unexplored areas based on a well-adjusted resource allocation that makes time-to-market targets achievable.

Key Highlights

A key highlight is that this review condenses the global R&D effort in the area of solid-state Li-ion batteries into easy to understand graphs. Connections and divergences can be identified between players that are very different in geographical location or size.

A ‘deep dive’ on cathode/solid electrolyte interface engineering options provides for inspiration as to how the longevity of solid-state Li-ion batteries can be further improved.
