BASF and CAMX Power LLC announced that BASF has been granted a license under the intellectual property of CAMX Power LLC (CAMX) relating to the CAMX suite of CAM-7 cathode materials for lithium-ion batteries. (Earlier post.) CAM-7 is a patented cathode material that harnesses the properties of high-nickel compounds to deliver high energy density with high-power capability.
The CAM-7 cathode material platform for advanced lithium-ion batteries, developed for over a decade by CAMX Power and now globally patent-protected, has been shown by key entities in the industry to be capable of extending the range of electric vehicles and the run time between charges in portable devices.
CAM-7 attributes include:
High energy density. Discharge capacity exceeds 200 mAh/g with first cycle efficiency of 92%.
High electrode density. CAM-7 can be processed easily into high active material density, high-performing electrodes with standard equipment and processes.
Excellent rate capability. CAM-7 supports very high discharge rates, with > 130 mAh/g delivered at 100C discharge rate.
High available energy for high power applications. CAM-7 cells can support high discharge pulse power over a wider state-of-charge window.
Low-temperature energy density. More than 80% of capacity retained at -20°C and 1C discharge rate – a critical requirement for automotive applications.
Low cost. Provides low cell-level cost (on a $/kWh basis).
Thermal stability. CAM-7 is stabilized through an innovative doping strategy and is engineered to resolve traditional thermal stability concerns regarding high-nickel cathode materials.
In BASF testing, the CAM-7 product platform has shown strong performance and is believed to have the potential to further increase energy density of lithium-ion batteries. CAMX has established a strong global IP position and we will be collaborating with CAMX’s experienced technical staff to develop advanced processing techniques to bring these products to the marketplace.—Kenneth Lane, President of BASF’s Catalysts division
Lab-based technology development company TIAX spun out its Advanced Battery Materials & Design Division in 2014 to become CAMX Power LLC. CAMX has lithium-ion battery material synthesis facilities, a development-purposed production/pilot plant for its flagship cathode material CAM-7 as well as design-purposed advanced cell making facilities.
Its portfolio, in addition to CAM-7, includes advanced cell designs and battery safety technologies/products. Alongside its Development Group, it has a Services Group to be able to tightly collaborate with its customers and the industry in general.
