"Scientists have created a microbattery that packs twice the energy compared to current microbatteries used to monitor the movements of salmon through rivers in the Pacific Northwest and around the world.

The battery, a cylinder just slightly larger than a long grain of rice, is certainly not the world's smallest battery, as engineers have created batteries far tinier than the width of a human hair. But those smaller batteries don't hold enough energy to power acoustic fish tags. The new battery is small enough to be injected into an organism and holds much more energy than similar-sized batteries.

Details of the battery, created by scientists at the Department of Energy'sPacific Northwest National Laboratory, were published online recently inScientific Reports, a member of the Nature collection of journals. Research about the battery's materials was also featured last year in the Journal of Materials Chemistry A." ---- Tom Rickey, PNNL, (509) 375-3732

Microbattery JellyRoll Technique

The battery is created by hand by rolling up layers of materials in a “jellyroll” technique. [Tom Rickey, PNNL, (509) 375-3732]
