Research and Markets: IP Overview Silicon-Based Anodes for Li-Ion Batteries Patent Landscape 2012

DUBLIN--(BUSINESS WIRE)--Research and Markets (http://www.researchandmarkets.com/research/4e8e52/ip_overview_silico) has announced the addition of the "IP Overview Silicon-based anodes for Li-ion batteries Patent Landscape 2012" report to their offering.

“IP Overview Silicon-based anodes for Li-ion batteries Patent Landscape 2012”

IP Overview presents a patent mapping analysis of the Silicon-based anodes for Li-ion batteries field. Carbon based materials are the almost only current commercial anode material (99% of the anode material's market).

The need for higher capacity for lithium-ion secondary cells has led to a search for replacement materials. Silicon would be a potential alternative of active material because its intercalation capacity is the highest known of 4200mAh/g, corresponding to a composition of Si5Li22. However, the large capacity fade observed during initial cycling has prevented the silicon anode from being widely adopted. Massive R&D and patent applications filings were conducted in order to prevent this capacity fading and improve overall performance of silicon-based anodes.

The present report analyses the patent environment and notably highlights the strategy of current major players. These major patent holders are end-users and fully integrated players (Sony, LG, Samsung, Panasonic), battery manufacturers (Sanyo, GS Yuasa, Hitachi, Hitachi Maxell), material manufacturers (Shin-Etsu Chemical, Sumitomo Metal Industries, Mitsui Mining Smelting, 3M ) and institutional players (Argonne National Laboratory, Chinese Academy of Science, AIST (JP), KAIST (KR)).
