CAMX Power introduces high performance cathode material for EV batteries

CAMX Power’s new cathode material uses less cobalt, a rare and difficult to source metal

CAMX Power has announced a fundamental invention that significantly improves the performance, while also reducing the cost, of lithium ion batteries, essential for the electrification of vehicles.

This significant breakthrough was originally conceived by TIAX and continued by CAMX when it became a separate company in 2014. The announcement was delayed until the key patents were obtained internationally. CAMX now has patents granted in the US, EU, China and Japan.

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 for at least the next 10 years in Li-ion batteries for EVs.

The patented invention has been named GEMX and the resulting enhanced chemistries, gNMC, gNCA, and gLNO.

CAMX Power president and founder Dr. Kenan Sahin stated: “About 50% of oil is used in transportation, contributing a huge amount of the environmentally hazardous greenhouse gas CO2 emissions. Electrification of vehicles is therefore critical to mitigating climate change and the far greater and more immediate risk, climate/weather volatility, which the world is already experiencing.”

“Lithium ion batteries are now the globally accepted technology to achieve electric vehicle production. More than 30% of the cost of a lithium ion cell is in the cathode material which is also the most difficult to manufacture in large quantities and hence the key to making batteries for vehicles affordable.”

High nickel cathode chemistries for vehicle batteries use cobalt to achieve required performance levels. While there is plenty of nickel and lithium to supply tens of millions of vehicles per year, cobalt is in shorter supply and is found in very few countries with many mired in controversy.

GEMX, through molecular engineering, places cobalt at critical places of the cathode particles resulting in less cobalt use, yet with greater stability, higher performance and lower cost for all classes of high nickel materials.

Dr. Sahin continued: “It is possible to achieve that at least 50% of global vehicle production be electric by 2045, with significant reductions in CO2 emissions, by which time both alternative energy and smart grids will be pervasive. California has already achieved 30% of its electricity being produced from alternative energy, targeting 100% by 2045. I am very proud that CAMX and TIAX have developed and patented this very important novel technology which can further accelerate the manufacture and spread of EVs.”
