General Motors, US DOE collaborate on lithium-ion batteries

General Motors (GM) and the US Department of Energy's (DOE) Argonne National Laboratory have signed a licensing agreement to use Argonne's patented composite cathode material to develop advanced lithium-ion batteries that last longer between charges and can charge at higher voltages.

General Motors (GM) and the US Department of Energy's (DOE) Argonne National Laboratory have signed a licensing agreement to use Argonne's patented composite cathode material to develop advanced lithium-ion batteries that last longer between charges and can charge at higher voltages.


The cathode material licensed to GM is be part of a diverse suite of lithium-ion battery inventions and patents developed at Argonne with DOE funding.

GM anticipates that use of the cathode material will yield advanced batteries that are high-performing, long-lasting and safe when compared to the existing technology.

US Energy secretary Steven Chu said that this agreement gives GM the ability to use cutting-edge battery technology throughout its supply chain.

GM executive director Micky Bly said that engineers and researchers at GM 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.

OMG Roofing Products - PowerGrip Universal

Eliminate Solar Rack Ballast and Reduce Rooftop Material Handling. PowerGrip™ Universal (PGU) is a commercial roof mount system designed to secure solar racks and other equipment to any type of commercial roofing system. PGU provides a secure connection directly to the roof deck or structural members and is designed to reduce or eliminate ballast in solar racking systems, so there's less weight on the roof and less material handling. Made of heavy-duty cast aluminum, PGU units include a base ring which is secured through the roofing cover and into the structural roof deck, and a waterproof top plate.
