Li-ion patent applications have grown by approximately 300% since 2010, mirroring the growth in the Li-ion market. <\/p>\n

A recent report published by UK-based IDTechEx reveals that the growth in patent applications has occurred across various technology groups, including NMC\/NCA and Li-Mn-rich cathodes, silicon anodes, electrolytes and electrolyte additives, separators and nanocarbon use.\u00a0<\/p>\n

\u201cSignificant growth in the number of applications per year was seen particularly between 2010-2015 and while all areas covered have seen growth since 2010, the number of patents regarding the use of nanocarbon in Li-ion have seen the most substantial growth over the past 10 years, in line with the growing hype and recent utilization of graphene and carbon nanotubes in Li-ion batteries,\u201d the report reads.<\/p>\n

According to the market researcher, geographically, Chinese assignees have been particularly active and have been responsible for much of the growth in total Li-ion patent applications over the past five to 10 years. <\/p>\n

\u201cSince 2011, Chinese assignees have been responsible for approximately 47% of all patent applications, compared to just 17% during the period 2001-2010,\u201d\u00a0 IDTechEx\u2019s document states. \u201cThis mirrors the growing importance of Chinese players in Li-ion development and suggests that beyond their dominance in processing and manufacturing, China may move into a dominant IP position too, especially if assignees start to file outside of China, which tends not to be the case currently.\u201d<\/p>\n

In the view of the British firm, competition between battery manufacturers is intensifying, emphasizing the importance of battery R&D and protecting innovation. <\/p>\n

\u201cDelving into the trends being seen in patent applications and filings can be used as a tool to provide insights into the key areas of innovation in Li-ion batteries, areas of development favoured by key players, and where R&D innovation is taking place,\u201d the report suggests.\u00a0\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
