Printed Batteries

Printed Batteries

Printing batteries, on paper or plastic or other substrates, has moved out of the lab and into commercial application. Processes that are more like spray painting or printing are replacing the older and more costly vacuum deposition process. This also increases the production speed.

The key advantages of Power Paper’s fully printable batteries include:

Thin and flexible allowing for custom design: At a thickness of only 0.6 – 0.7 mm. The thin battery is flexible and can be bent or twisted repeatedly at sharp angles. The printed batteries have the same elasticity and flexibility as the paper or plastic surface onto which they are printed, and can be shaped to fit the size, thickness, and form of a wide range of products for cosmetic, consumer, medical, industrial and defense applications.

Printing promises to make electronics cheap, flexible, and scalable. Printed solar cells, sensors, and displays are already close to market, and makers of energy-storage devices are now starting to catch on. Two printable battery start-ups, with different technologies targeting different applications, described their devices at the Printed Electronics conference in Santa Clara, Calif., on 2 December.

Planar Energy Devices, an Orlando, Fla.–based spinoff of the U.S. Department of Energy’s National Renewable Energy Laboratory, has developed a technique to print solid-state lithium batteries for electric vehicles. Its printed batteries store more energy, last longer, and are safer than their commercial counterparts, according to the company.

Troy, N.Y.–based Paper Battery Co., meanwhile, is making flexible 100-micrometer-thick energy-storage sheets that could be molded onto electronics and medical devices or laminated beneath flexible solar panels. Both companies claim they should be able to print meters of batteries at a low cost.

Cutting-edge consumers eagerly awaiting their chance to purchase a Chevy Volt or a Nissan Leaf will put their trust in lithium-ion batteries that have been scaled up to electric-vehicle proportions. By the time second-generation plug-in hybrid and all-electric vehicles reach the masses, they will contain much more powerful batteries sporting a new technology. But what that technology will be is still not known.

The future of electric-car batteries is a wide-open research and development space and a huge opportunity for U.S. science and manufacturing, experts say. For the U.S. to emerge in front of its global competitors, however, one or more of a host of possible advanced technologies must prove its mettle.
