About the subject

For the past 15 years, silicon has gained a lot of attention as an alternative to graphite for the Li-ion battery anode. It has one of the highest known specific capacities for Li-ion battery anodes, a relatively low working potential, a high natural abundance, and an environmental friendliness. However, silicon has a huge volumetric fluctuation (>300%) during charge/discharge, leading to poor cycle life, drastic irreversible capacity loss, and low coulombic efficiency. As a result, many companies, start-ups, and R&D laboratories are developing silicon anode materials and Li-ion batteries with silicon anodes, and their efforts have begun to show rewards.

In this context, patent analysis is a complementary approach to market research that can help to gain a better understanding of the competitive landscape, technological roadmap, cutting-edge technology developments, and competitors’ strategies. It can also help to identify companies, technical solutions, and strategies not identified by market analysis.

Based on our analysis of the patent landscape related to silicon anodes for Li-ion batteries, we will reveal the main IP trends, key IP players and newcomers, their IP strategies and IP strengths per supply chain position (materials, electrodes, cells) and types of silicon materials (pure silicon, core-shell material, composite material, silicon shapes, etc.) as well as the key patented technical solutions envisioned to overcome silicon anode challenges. Special focus will be placed on the main patent litigations related to silicon anode.
