[quote]3D printing can be used to print lithium-ion micro-batteries the size of a grain of sand which could sufficiently power miniature devices, reveals a study from a team of scientists at Harvard University and the University of Illinois at Urbana-Champaign.To make the micro-batteries, the team printed precisely interlaced stacks of tiny battery electrodes, each less than the width of a human hair. Manufacturers have until now generally had to use solid-state batteries, created by depositing films of solid materials to build the battery electrodes. These batteries were often as large, or larger, than the devices themselves, defeating the purpose of miniaturisation. The solution was to design ultra-thin solid-state batteries, which then proved insufficient in powering the tiny devices. The scientists in the study realized they could shove more energy into a micro-battery by creating stacks of tightly interlaced, ultrathin electrodes that were planar-built, for which they turned to 3D printing.[/quote] [URL]http://eandt.theiet.org/news/2013/jun/micro-batteries.cfm[/URL] [URL]http://www.treehugger.com/clean-technology/3-d-printing-tiny-lithium-batteries-video.html[/URL] (Video) Seems like a new way of creating batteries has been developed, allowing for absolutely tiny batteries that last as long as the big batteries we're used to now. This could have massive implications in all fields of technology. Also, first time ever posting a news article. Hope I didn't mess it up/am late with this news.
Man, 3D printing can go far, especially to make things such as batteries.

Ah damnit, I searched for battery and tiny, and another few terms, but none used in that thread title. Mod can close this. I tried. :(
