ZSW develops process for Li-ion batteries with extended cycle life; 10,000 charge cycles

Green Car Congress

Scientists at the Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg (ZSW) (Center for Solar Energy and Hydrogen Research Baden-Württemberg) have developed Li-ion batteries that have already demonstrated a very high cycle life of more than 10,000 full cycles with retention of more than 85% of original capacity.

Project shows maritime fuel cell generator can increase energy efficiency by up to 30% at part load; reliability and cost issues

Green Car Congress

A report authored by Sandia National Laboratories on the project found that the project showed that it is possible to increase energy efficiency by up to 30% at part load and reduce emissions to zero through the use of hydrogen fuel cells. One opportunity to do so was identified in Honolulu Harbor at the Young Brothers Ltd. (YB)

Top 15 Nissan LEAF markets in US in 2013

Green Car Congress

Another three are on the West Coast and in Hawaii: Seattle (4), Portland (5), and Honolulu (6). LEAF performs well because of a good charging infrastructure, a dense urban footprint and congestion. Honolulu, with 26 quick chargers, has one of densest charging grids in the US. Los Angeles.

More details on work supporting NEC prototype 4.5V Li-ion battery; modified LiNiMnO cathode and fluorinated electrolyte

Green Car Congress

The new cathode and electrolyte solution improve battery energy density by approximately 30%. O 4 is a promising next-generation cathode material that has attracted the interest of multiple research teams because of its large capacity and its high charge-discharge potential of around 4.65V versus Li.

USC team uses mixed conduction membranes to suppress polysulfide shuttle in Li-S batteries

Green Car Congress

One of the major issues hobbling the commercialization of high energy-density lithium-sulfur batteries is the “polysulfide shuttle”—the shuttling of polysulfide ions between the cathode and anode.
