A team of researchers have found a way to create lithium batteries that minimally affect the environment: they use viruses to make them. The viruses use no high temperature and pressures, and therefore very little energy: all they need is water. They have been genetically engineered to form the negative and positive ends of batteries by coating themselves with cobalt oxide and gold (negative), and iron phosphate and silver (positive). The species used is a bacteriophage, not harmful to humans.
Lithium is also playing a part in several green ventures, such as the lithium-air batteries that scientists hope will replace gasoline some day.
