National University of Singapore researchers devise membrane-based supercapacitors; possible new route to high-performance supercapacitive energy storage

Green Car Congress

Unlike more conventional supercapacitor electrode materials with large surface areas and high porosities, the new hydrophilized polymer network uses ion-conducting channels for fast ion transport and charge storage. When sandwiched between and charged by two metal plates, the membrane can store charge at 0.2 —Xie et al.

Sandia researchers developing new family of metal-based ionic liquids for low-cost, efficient flow batteries

Green Car Congress

Sandia researchers have developed a new family of electrochemically reversible, metal-based ionic liquid (MetILs) that could lead to non-aqueous redox (reducing-oxidizing) flow-battery energy storage systems ( earlier post ) able to cost-effectively store three times more energy than today’s batteries.

24M emerges from stealth mode with new semi-solid Li-ion cell; <$100/kWh by 2020

Green Car Congress

Co-founded by MIT’s Dr. Yet-Ming Chiang, 24M’s Chief Scientist, the company is leveraging existing, preferred energy storage chemistry but using a new cell design with semi-solid (a mixture of solid and liquid phases) thick electrodes and manufacturing innovations to deliver what it says will be up to a 50% reduction in current Li-ion costs.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

Electricity is a commodity that is bought and sold, and yet unlike most other commodities, it cannot easily be stored. The need for large-scale electrochemical energy storage as a grid-stabilizing source of demand disappeared. Once electricity is generated and passes into the grid, it is typically used almost immediately.

Axion supplying PbC batteries to Norfolk Southern for all-battery switcher and working on line-haul hybrid locomotives; micro-hybrid and stationary expansion

Green Car Congress

PbC batteries are multi-celled asymmetrically supercapacitive lead-acid-carbon hybrid batteries. Like a lead-acid battery, it comprises a series of cells. NS originally built NS-999 in early 2009 with leadacid batteries; however, the leadacid system consistently failed field testing.
