Researchers Create Paintable Battery
Researchers at Rice University have developed a lithium-ion battery that can be painted on virtually any surface. The rechargeable battery created in the lab of Rice materials scientist Pulickel Ajayan consists of spray-painted layers, each representing the components in a traditional battery. In an experiment, nine bathroom tile-based batteries were connected in parallel. One was topped with a solar cell that converted power from a white laboratory light. When fully charged by both the solar panel and house current, the batteries alone powered a set of light-emitting diodes that spelled out ?RICE? for six hours; the batteries provided a steady 2.4 volts. The researchers reported that the hand-painted batteries were remarkably consistent in their capacities, within plus or minus 10 percent of the target. They were also put through 60 charge-discharge cycles with only a very small drop in capacity. In this video, graduate student Neelam Singh describes the team's process.
