Today, scientists are working to design batteries to build into a variety of objects. In 2012, researchers developed a paint-on lithium-ion battery consisting of five layers, just like conventional lithium-ion batteries. This technology could change the way batteries are manufactured and enable more surfaces to be used for energy storage. In 2014, researchers in China developed lithium-ion batteries that can be stretched as much as 600 percent, as stated in Scientific American. Fiber-shaped batteries based on this technology could be woven into textiles for wearable devices of the future. Still other teams are working on making thin and flexible lithium-ion batteries.
