Scientists have developed a lithium ion battery shaped like the human spine that can power flexible and wearable electronics. Up to now, however, researchers have had difficulty obtaining both good flexibility and high energy density concurrently in lithium-ion batteries. Researchers at Columbia University in the US developed a prototype battery shaped like the human spine that addresses this challenge. The battery allows remarkable flexibility, high energy density and stable voltage no matter how it is flexed or twisted, researchers said. "Because of the high proportion of the active materials in the whole structure, our spine-like battery shows very high energy density higher than any other reports we are aware of," he said.
