Nanotubes Boost Battery Capacity by 50 Percent
South Korean researchers have developed a nano-structure that could spike the power of rechargeable lithium-ion batteries, which are increasingly used in electronic devices and cars.
In lithium-ion batteries, which are rechargeable, lithium ions move between the battery's anode and cathode. The high energy density of the batteries accounts for their common use in consumer electronics products, especially portable devices. Their popularity in automotive and aerospace applications is growing and nanostructured, or nano-enabled, batteries are emerging as the new generation of lithium-ion batteries for their edge in recharging time, capacity and battery life.
A team of scientists led by Korea Advanced Institute of Science and Technology (KAIST)'s Song Hyun-joon said they developed a nano-structured material using copper oxide (CuO), which could produce lithium-ion batteries with some 50 percent more capacity than conventional products.
