Rep. Barbara Lee, D-Oakland, was up in Berkeley this morning to visit PolyPlus Battery Company, which is developing lightweight, nontoxic lithium batteries that use seawater or air to produce clean energy.
Chief Technical Officer and Vice President Steven Visco demonstrated one by dropping a battery attached to an LED light bulb into a glass of water; that light would stay on for two and a half to three months, he said. A bundle of the batteries weighs only 24 grams, he noted, while the dozen or so standard AA batteries required to produce an equivalent amount of energy would weigh 340 grams and a standard lithium cell would weigh 240 grams.
These batteries are going to revolutionize marine energy needs including deep-sea exploration, Visco said; they’re getting close to commercial production techniques for another version of their battery that uses air rather than seawater.
PolyPlus just a few weeks ago landed a grant of almost $5 million from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E), funded through the American Recovery and Reinvestment Act, to develop a rechargeable version of the lithium-air battery for use in electric vehicles.
“It will take time,” Visco cautioned. “Any new battery chemistry is going to take a while to get from small devices – laptops, cell phones – to electric vehicles.”
And there will be applications beyond that, he promised, noting the 35 pounds of batteries U.S. troops often must carry now could be reduced to one-tenth that weight.
PolyPlus, founded in 1991 as a spinoff from Lawrence Berkeley National Laboratory, remains a small firm but has trained people with little or no scientific expertise to undertake the company’s work, Visco said; now they’re seeking venture capital to launch a production facility, also in Berkeley, that could create a host of new jobs.
After PolyPlus, Lee visited the Joint Bio-Energy Institute in Emeryville, a partnership led by the Lawrence Berkeley National Laboratory that has received $7.6 million in federal funding for development of next generation bio-fuels. And then she visited Amyris Biotechnologies in Emeryville, which has received $24 million in stimulus grants to support its efforts to create renewable fuels and chemicals.
After that, Lee spoke this afternoon at the Alameda County Transgender Health and Resource Conference in Oakland’s Preservation Park, an event is designed to connect the transgender community with community resources outside of the scope of HIV/AIDS testing.
