Silicon Anode for Li-ion Batteries – Patent Landscape Analysis 2024

The recognized potential of the silicon-based anode for Li-ion batteries has led to significant investments in bringing this technology to market

Today, the use of silicon-based anodes in Li-ion batteries is becoming a reality, with billions od dollars flowing into silicon anode start-ups (IDTechEx, 2021) and a market for silicon anode material for Li-ion batteries projected to reach $24 billion by 2034 (IDTechEx, 2024). Several material manufacturers, such as Advano, Sila Nanotechnology, Elkem, Group14, NanoGraf, OneD Materials, and Nexeon, have announced the commercial production of silicon active materials for Li-ion batteries.

Likewise, several battery manufacturers have announced the commercial availability of silicon anode Li-ion cells, including Amprius, Sionic Energy (formerly NOHMS), Farasis Energy, Enovix, StoreDot, Samsung, Panasonic, PPES (a joint venture between Toyota and Panasonic), Murata, and Enevate/EnerTech. In the automotive sector, there have been significant strategic acquisitions and partnerships. Tesla acquired battery manufacturer Maxwell Technologies in 2019 and battery start-up SiLion in 2021.

That same year, PPES and Nexeon announced a partnership focused on silicon anode development, and StoreDot entered into a strategic framework agreement with EVE Energy, while partnering with Group14 Technologies to accelerate commercialization of StoreDot’s XFC lithium-silicon cells for electric vehicles. Additionally, automotive OEMs such as Daimler, Porsche, and GM have recognized the potential of silicon anodes and have invested in and partnered with silicon anode companies.

In this highly competitive and dynamic environment, it is increasingly crucial to have a strong understanding of the patent landscape and the strategies of key players in technology and intellectual property (IP). To meet this need, the Publisher is releasing a new Silicon Anode Batteries Patent Landscape report, which aims to clarify the current positions of IP players, analyze their IP strategies, and reveal where industry leaders, newcomers, and start-ups are focusing their R&D efforts.

Key Features of the Report:

• PDF >100 slides
• Excel file >18,200 patent families
• Global patenting trends, including time evolution of patent publications, countries of patent filings, etc.
• Main patent assignees and IP newcomers in the different segments of the supply chain.
• Key players’ IP position and the relative strength of their patent portfolio.
• Patents categorized by categorized by supply chain segments (materials, anode, battery cell, other battery components).
• Recent patenting activities of key players.
• Focus on startups, pure players, and IP newcomers.
• Excel database containing all patents analyzed in the report, including patent segmentations and hyperlinks to an updated online database.

Scope of the Report:

• This report provides a detailed picture of the patent landscape related to Silicon Anode for Li-ion Batteries, covering the whole value chain (anode materials, anode electrode, battery cells, electrolytes, binders, etc.)
• We have selected and analyzed more than 38,750 patents and patent applications published worldwide up to September 2023, representing more tha18,200 patent families (inventions) relevant to the scope of this report.
• The patent search strategy has been implemented using advanced search equations in the patent database and by a cautious patent selection performed by the analyst to get the most relevant corpus.
