Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) are turning to extremely tiny tubes and rods to boost power and durability in lithium-ion batteries, the energy sources for cell phones, laptops, and electric vehicles. If successful, the batteries will last longer and perform better, leading to a cost advantage for electric vehicles.
Transportation and communication around the world increasingly rely on lithium-ion batteries, with cell phones ubiquitous on six continents, and electric vehicles on pace to accelerate from a $1 billion worldwide market in 2009 to $14 billion by 2016, according to analysts Frost and Sullivan.
NREL's Energy Storage group is working with the Energy Department, automotive battery developers, and car manufacturers to enhance the performance and durability of advanced lithium-ion batteries for a cleaner, more secure transportation future, said Energy Storage Group Manager Ahmad Pesaran. "The nanotube approach represents an exciting opportunity—improving the performance of rechargeable lithium-ion batteries while make them last longer," Pesaran said. "Increasing the life and performance of rechargeable batteries will drive down overall electric vehicle costs and make us less reliant on foreign sources of energy."
