NEC develops prototype 4.5V, long-life manganese Li-ion battery; 30% more energy density, high capacity and light weight

Green Car Congress

NEC presented the new cell at PRIME 2012, the Pacific Rim Meeting on Electrochemical and Solid-State Science, in Honolulu. To enable this, NEC changed the solvent of the electrolyte solution from a conventional carbonate-based solvent to a fluorinated solvent that is highly resistant to oxidation. from the 3.8V

ARPA-E to award $22M to 18 projects to accelerate production of macroalgae for energy and other uses; MARINER

Green Car Congress

Macroalgae can be utilized as a feedstock for domestic transportation fuels, chemicals and other commercial products without competing with food crops for land and water. Today, nearly all domestic biomass produced for electricity generation and liquid fuels occurs on land. —ARPA-E Acting Director Eric Rohlfing.

Alcoa and Phinergy enter joint development agreement for high energy-density aluminum-air batteries

Green Car Congress

Aluminium–air cells are high-energy density primary (non-rechargeable) batteries originally developed in the 1960s. Phinergy says that it has developed a proprietary process of anode production resulting in increased use of aluminum energy, while reducing the unwanted chemical reactions. Earlier post.).
