based Envia Systems to provide GM’s battery engineering team with access to advanced lithium-ion cathode technology that delivers higher cell energy density and lower cost. Envia’s cathode technology also will offer benefits for other devices and applications where low-cost, high-energy density storage solutions are needed. MORE >>

The military is interested in replacing lead-acid batteries with higher performing Li-ion systems. A123 Systems has introduced the Military 6T Battery, a robust Li-ion battery system engineered specifically to meet the demanding requirements of military vehicles. From a 2011 TARDEC presentation.

Benson from Stanford University and Stanford’s Global Climate and Energy Project (GCEP) has quantified the energetic costs of 7 different grid-scale energy storage technologies over time. We find that annual material resource production places tight limits on Li-ion, VRB and PHS development and loose limits on NaS and CAES. MORE >>

SK Energy, Asia’s fourth largest energy provider and Korea’s first oil refining company, develops and manufactures lithium-ion battery separators (LIBS) as well as lithium-ion batteries for applications ranging from consumer electronics to transportation. SK cells have a specific energy density of around 140 Wh/kg. MORE >>

Australia-based Galaxy Resources Limited has signed a technology license agreement with US-based lithium-ion battery producer K2 Energy Solutions Inc. Galaxy will have the unrestricted and unlimited use of specific K2 Energy lithium battery technologies, valuable for the E-bike and other battery markets. Earlier post.) Cattlin. MORE >>
