Silicon Anode patent landscape

Silicon Anode Materials Patent Landscape Report 2020


Lithium-ion batteries (LIBs) are the most widely used batteries in portable devices. But one of the leading markets for these batteries is in electric vehicles, which have not been grown sufficiently due to their low energy density. Silicon as an anode material of LIBs with high capacity can solve these challenges.

This report analyzes patents (over the last ten years) of silicon anode materials used in lithium-ion batteries to investigate their technological development trends. In this report, the previous ten years in silicon materials used in the anode of lithium-ion batteries were examined by three categories of patents. The first category is patents of large battery companies, the second category is patents of startups, and the third category contains patents of top researchers. These three categories of patents have been collected separately, and after extracting their information, they have been divided into two categories: strategic and technical analysis. The results of patent information can be used to identify companies' strategic and technological perspectives and analyze the maturity of silicon material preparation technology, compounds, and structures. In other words, everything about leading players and their approach to silicon anode technologies is available. Reading this report enables you easy to monitor the research in top laboratories in the world. Also, articles published in top journals during 2018-2021 can inform you of academic approaches in silicon anode technologies.

Useful Excel patent database

The report also includes an Excel database with the 7000+ patent families (inventions) analyzed in this study. This valuable patent database allows for multi-criteria searches. It includes patent publication numbers, title, abstract, priority dates, citation, oldest priority date, patent assignees, family size, patent’s current legal status, and technical information. From the patents were extracted: (the name of the composition investigated, the type of coating possible, the composition structure, the raw material, the method of preparation, the challenge sought by the inventor, the improved electrochemical properties, and the application described in the patents and something like that.
