Lithium cells the size of rice

A video on Treehugger shows how scientists have produced lithium-ion batteries from a nozzle the width of a human hair. Although only ever likely to be used for small, low power gadgets, these minute batteries actually deliver enough current to be of real use, unlike previous attempts using thin-film printing.

The team that produced this marvel of miniaturisation works at the Wyss Institute for Biologically Inspired Engineering at Harvard University.

Harvard gets funding for organic flow battery

The US Advanced Research Projects Agency Program-Energy (ARPA-E) will be providing a team from Harvard University with USD$600,000 to develop a rechargeable flow battery whose chemistry will be based on organic molecules derived from plants, reports Knovel. In total, ARPA-E is allocating USD$130 million for 66 energy storage grants.

The largest of these was given to the PolyPlus Battery Company, to develop an aqueous rechargeable lithium-sulfur battery. Besides this, the company also received USD$9 million from the Department of Energy’s Advanced Manufacturing Office this summer, The Green Optimistic says.
