Figure 1: Time evolution of COSMX’s patent publications related to silicon anode for Li-ion batteries and published until September 2024. The majority of COSMX ’s silicon anode-related patents focus on electrode manufacturing or design, and silicon anode-based battery cells (Figure 2).
Up to 2021, SK Innovation filed only two patent applications linked to solid-state batteries. One of them is dedicated to a spinel lithium manganese oxide cathode material coated with solid electrolyte ( US8142932 ). The other claims a high-voltage solid-state battery cell without specifying the nature of the solid electrolyte ( US11127985 ).
Today, the solid-state battery patent corpus counts for more than 12,000 patent families (inventions), of which more than 520 were published in the first quarter of 2022 alone. In such a dense and dynamic landscape, it is important to be aware of how the competitors move, and secure one’s IP position.
All year long, Knowmade’s analysts investigate patenting activities related to solid-state batteries through a dedicated Quarterly Patent Monitor.
