Techniques that produce holograms have helped researchers create little lithium-ion batteries that could power microelectronic devices, such as sensors, medical implants, and radio frequency transmitters.

As engineers continue to shrink the size of electronics, they stoke a growing demand for miniaturized power supplies. Although researchers have already created millimeter-sized microbatteries, these generally fail to store sufficient energy or produce enough power for devices.

Engineers at the University of Illinois, Urbana-Champaign, recently demonstrated that porous, three-dimensional . . .
