The recognized potential of the silicon-based anode for Li-ion batteries has led to significant investments in bringing this technology to market
Silicon-based anodes in Li-ion batteries offer superior electrochemical performance, including higher energy density, greater gravimetric and volumetric capacity, suitable thermodynamic lithiation potentials, and higher average voltage.
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, Knowmade 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.
A dynamic IP landscape
IP competition analysis should reflect the vision of players with a strategy to enter and develop their business in the silicon anode Li-ion battery market. In this report, Knowmade’s analysts provide a comprehensive overview of the competitive IP landscape and latest technological developments in this field. The report covers IP dynamics and key trends in terms of patents applications, patent assignees, filing countries, and patented technologies. It also identifies the IP leaders, most active patent applicants, and new entrants in the IP landscape. The report also sheds light on under-the-radar companies and new players in this field.
Evolution of leading players’ positions and entry of new patent applicants
LG Chem/LGES is leading the silicon anode battery patent landscape, with strong IP competition from Samsung, Murata, Panasonic/Sanyo, and Toyota. Additionally, we have identified over 290 start-ups and pure players involved in the patent landscape, and more than 650 new entrants who filed their first silicon anode-related patents in 2021 or later, most of whom are Chinese entities. In dedicated sections of the report, we focus on the IP portfolios held by key players, start-ups, and newcomers from various countries.
