Based on a proprietary machine learning patent literature analysis and hands-on energy storage industry knowledge, we describe the global supercapacitor innovation environment.

IP radar diagrams illustrate how different players are positioned along the value chain (materials, cells, modules and end applications). We illustrate correlations between different applications and specific capacitor types (EDLC - electric double-layer capacitor, symmetric and asymmetric hybrid capacitors) and where IP activity is moving.

In the technology stack analyses, we group patents around current or potential commercial products, such as ‘EDLC cells with high temperature resistance’ or ‘asymmetric hybrid capacitors based on dry processed carbon electrodes’. For large companies with hundreds of patent filings, we identified up to 4 different technology stacks, allowing for the assessment of large patent portfolios in a well digestible format.

Findings are combined with market information to illustrate the competitive innovation position of each player.

Scope

IP radar diagrams and key patents are listed for 109 companies with links to the patent full text. 51 companies are described in more detail based on a technology stack analysis and with links to product description websites (if available).

Reasons to Buy

  • This review provides energy storage professionals with an objective and future-looking basis to assess which companies will be innovation leaders in the future.
  • Readers will understand which players will enjoy a competitive innovation advantage depending on two different scenarios: 1) EDLCs will dominate the market; 2) hybrid capacitors will dominate the market.

Methodology

The patent information source for this publication is the European Patent Office (EPO), which covers patent filings from more than 100 patent offices around the world. A machine learning (ML) model was defined for supercapacitors that consists of several thousand data points. Patent documents published between 2010 & July 2018 were selected based on ML relevancy scores.
