As OEMs continue to announce plans to end production of diesel engines, Mercedes-Benz has unveiled its new diesel PHEV C-Class at the Geneva Motor Show. Will this powertrain development give TDI a new lease of life? 


GM signs Argonne deal

General Motors and the US Department of Energy's Argonne National Laboratory have announced that they have reached a worldwide licensing agreement to use Argonne's patented composite cathode material to make advanced lithium-ion batteries that last longer between charges and can charge at higher voltages.

"The creation of this battery technology represents an important return on the American investment in innovative vehicle and battery research,” said Energy Secretary Steven Chu. “This agreement gives General Motors the ability to use cutting-edge battery technology throughout its supply chain. The licensing of this technology will also spur the renewal of the American battery industry, creating hundreds of new jobs where they are needed most.”

The agreement with Argonne builds on GM’s commitment to lead the development of vehicle electrification technologies designed to meet the diverse needs of customers around the world, said Micky Bly, GM executive director of electric systems, hybrids, electric vehicles and batteries.

“Engineers and researchers at General Motors are working on next-generation battery systems that will reduce cost while providing improved performance, expanding the practicality and affordability of electric vehicles in the future,” Bly said.

“The goal of Argonne's battery research is to support the US automobile industry," said Jeff Chamberlain, who heads Argonne's energy storage Initiative. "The transfer of this technology is a powerful example of how basic research and technology development performed at a DOE national laboratory can produce technology that is useful to US citizens.

“The added benefits of this endeavor are the potential creation of U.S.-based green jobs, lessening U.S. dependence on foreign sources of oil and a reduction in greenhouse gas emissions."

The cathode material licensed to GM is part of a large, diverse suite of Li-ion battery inventions and patents developed at Argonne with DOE funding. The agency also provided funding for early science research that helped develop this technology. Use of the cathode material will yield advanced batteries that are high-performing, long-lasting and safe when compared to the existing technology that has dominated the market for nearly two decades.

Compared with currently available materials, Argonne's composite cathode material has a unique combination of lithium- and manganese-rich mixed-metal oxides in a stable materials-design approach that will: extend the operating time between charges and increase the calendar life of batteries; improve the inherent safety of lithium-ion cells; and allow charging at higher voltages, which leads to a substantially higher energy storage capacity.

"The fact that GM is including Argonne's novel composite cathode material in their commercialization process is a testament to the world-class scientists performing research in this area at Argonne and the long-term vision and commitment by DOE," said Eric Isaacs, Argonne director and president of the UChicago Argonne, a wholly-owned laboratory management subsidiary of the University of Chicago.

Argonne has also announced that it has licensed its cathode technology to LG Chem for use in battery cells used in the Chevrolet Volt electric car with extended-range capability.

"The scientists and engineers in Argonne's battery department look forward to continuing this important work for next-generation electric vehicles, as well as for new energy storage technologies for the power grid,” Isaacs said.
