Silicon Anode for Li-ion Batteries Patent Landscape 2022
Description
Silicon Anode for Li-ion Batteries Patent Landscape 2022
The Silicon anode-related patent landscape is very dynamicAutomotive represents a huge new potential market for the battery industry. Electric vehicle (EV) performances mainly rely on batteries, and companies operating in this field are investing a lot to meet their requirements in terms of autonomy, energy density, charge duration, lifetime and safety. R&D developments in the battery field are constantly increasing and multiplying at all supply chain levels. One solution envisioned to improve battery performances is to develop new silicon-based anode to replace graphite. Indeed, silicon anode-based Li-ion batteries show higher electro-chemical performances, and silicon is environmentally friendly and low-cost material.
In this context, Knowmade is releasing a new patent landscape report covering the whole supply chain of silicon anode-based Li-ion batteries, from anode materials, electrodes and binders, to battery cells, electrolytes and equipment. Silicon anodes for Li-ion batteries is a booming industry, and the level of intellectual property (IP) activity is growing fast with numerous newcomers entering the game. Patent landscape analysis is the perfect complement to market research, to fully comprehend the competitive landscape and technology roadmap, keep up with new technology developments, anticipate future technology adoption, and understand the different competitors’ strategies. This kind of patent landscape report reveals the companies, technical solutions and strategies not identified through standard market analysis.
Knowmade’s analysts have selected and analyzed more than 24,700 patents and patent applications grouped in more than 12,300 patent families (inventions) related to the whole supply chain of silicon anode-based Li-ion batteries (electrode materials, electrodes, electrolytes, battery cells). We have identified more than 1,800 different patent assignees involved in the Silicon anode patent landscape. The significant proportion of patents granted worldwide reflects a certain maturity of silicon anode technology for Li-ion batteries which is now being adopted by the industry. Nevertheless, numerous patent applications are still pending, meaning that R&D developments are still ongoing to solve technical issues related to silicon anode batteries.
