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

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…
