Johnson Matthey extends tech license ahead of battery launch

November 23, 2018 // By Nick Flaherty
Johnson Matthey is extending its license for platform of IP around nickel based high energy high power cathode materials ahead of the launch of its lithium-ion batteries in electric vehicles (EVs).

The GEMX IP platform is based on a fundamental invention of US-based CAMX for which broad patents have been granted in the US, EU, Japan and China. The invention creates a broad class of cathode materials, overarching the high nickel material classes NMC, NCA and LNO, the chemistries currently used, and expected to be used in the next ten years or more, in lithium-ion batteries for EVs. Using molecular engineering, GEMX places cobalt at the critical places of the cathode particles resulting in the use of less cobalt, yet with greater stability, higher performance and lower cost for all classes of high nickel materials.

"We are pleased to have obtained this further license from CAMX to support JM's development of ultra high energy density automotive battery cathode materials," said Alan Nelson, Sector Chief Executive and CTO at JM.  "This license improves and extends our intellectual property protection and supports the commercialisation plans for our market leading eLNO technology." The move is part of a re-focus on materials and batteries after it sold off its UK-based battery management system business.

"Adding the GEMX platform also gives us a broader chemistry landscape to which we can apply JM's expertise in materials design, development, scale up and manufacturing.  This is how JM provides our customers, and ultimately consumers, with battery materials that have the performance characteristics required to drive an electric vehicle revolution and enable the journey to pollution-free roads. 

"In May 2016, Johnson Matthey purchased a license for the CAM-7 platform of CAMX. Using its own processing technologies and other know how Johnson Matthey successfully developed eLNO and is currently commercialising its technology. With the GEMX license JM can further enhance eLNO as well as take an advanced position in other material classes such as NCA and NMC," said Dr. Kenan Sahin, president and founder of CAMX. "Also with the GEMX license which extends CAM-7, JM will now have patent protection beyond 2030 in the key jurisdictions in
