General Motors Researchers Develop Improved Li-S Cathode Material

General Motors Researchers Develop Improved Li-S Cathode Material

A research team from General Motors Global Research & Development Center recently published an article on their progress in improving lithium-sulfur batteries. Li-S batteries have a few times greater energy density then today’s lithium-ion batteries.  However, Li-S batteries typically don’t last long. The GM team achieved for now 900 mA…

We divide the ​LFP electrode into 10 representative volumes, each containing 10 ​LFP particles immersed in a liquid electrolyte and connected electronically through the carbon network. A one-dimensional Cahn–Hilliard equation (equation (2)) governs the Li diffusional chemical potential along the a axis of each particle. A Butler–Volmer equation (equation (3)) governs the insertion and removal of Li.

Rapid Charging/Draining Of Lithium-Ion Batteries Less Damaging Than Previously Thought

According to an article published in Nature Materials by researchers from Stanford University and the Stanford Institute for Materials & Energy Sciences (SIMES) at the Department of Energy’s SLAC National Accelerator Laboratory, and colleagues from Sandia National Laboratories, Samsung Advanced Institute of Technology America and Lawrence Berkeley National Laboratory, quick…

Dissecting the Nissan LEAF Battery (w/video)

After the fun of seeing the Tesla battery pack innards, it seems only fair to take a look at the guts of other cars’ batteries – notably the Nissan LEAF.  Most of this information comes from the salvage site Hybrid Auto Center, (and we’re in no way promoting or representing…

Dormant Phillip Morris Facility

Has North Carolina Entered The Modern Battery Arena?

In April, a firm registered as Victory Industrial Park LLC quietly purchased a 2,100 acre compound in Concord North Carolina for $68.5 million. The park was formerly occupied by cigarette giant Phillip Morris who closed the facility in 2007, eliminating 2,500 jobs from the Concord NC tax base. Victory has declined…

NASA Bets On Silicon-Anode Li-ion and Li-S Batteries

NASA recently announced four proposals for advanced energy storage technologies that may be used to power the agency’s future space missions. As it turns out, NASA is looking in a similar direction as automotive industry, seeing the future in silicon-anode Li-ion and Li-S batteries. Noteworthy is that one of the…

Subsidy Independent EVs, Solar And Battery Storage By 2020

Last month investment bank UBS  released a report charting the disruptive triangle of solar, EVs, and energy storage. The report claimed that by 2020, payback time for unsubsidized investment in EVs, solar, and battery storage will be as low as 6-8 years – triggering global changes in the energy industry. The report…
