Scientists have generated high resolution images of lithium ions being deposited on a single nanowire anode, revealing how the material grows and flexes in response to charge. The US and Chinese researchers say the technique will help in the development of more advanced battery systems in the future. Lithium ion batteries are widely used, but as they are charged and discharged the anode material inside the batteries undergoes large volume changes, which leads to strain in the material causing it to break up. Nanowire anode materials are able to charge and discharge without this breaking thus prolonging the battery's life, but...
