Georgia Tech team develops conversion-type iron-fluoride Li battery cathode with solid polymer electrolyte

Green Car Congress

Researchers at Georgia Tech have developed a promising new conversion-type cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte. The Georgia Tech team sought to overcome those obstacles by using the solid polymer electrolyte.

The Battery Revolution Is Just Getting Started

Cars That Think

Thirty-two years later, our laptops are powered by much, much lighter lithium-ion or lithium-polymer batteries. Not only will batteries be needed for our phones, laptops, power tools, cars, ships, and planes, but also to store energy from renewable sources. Within each of those cells is a chemical paste that stores the charges.

ARPA-E announces $98M in funding for 40 OPEN projects; two opposed-piston engines projects receive $10M total

Green Car Congress

A motor-generator integrated on each engine crankshaft will provide independent control to each piston and eliminate all torque transmitted across the mechanical crankshaft connection, thus reducing engine size, mass, cost, friction, and noise. Novel Polymer-enhanced Rechargeable Aluminum-Alkaline Battery Technology – $2,000,000.

OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

Green Car Congress

The shelf-life of stored charge in rechargeable devices does not scale linearly with maximum SP and has led to trends referred to as ‘range-anxiety’, ‘compulsive charging’, etc. Applying an electrical potential to the conducting polymer membrane alters the redox state, allows it to conduct ions across the membrane.
