TimeMachine: Micro batteries made with 3D printing unibody damage New applications of 3D printing could enable the development of miniaturized medical systems, miniaturized electronics, small robots and more.
In a previous article we've already dealt with this topic, now scientists have published this work with interesting construction details. A recent use of 3D printing has allowed the creation of micro lithium-ion battery the size of a grain of sand. These batteries can provide power for very small devices, in particular in the field of medicine or communications; many of these are still on the benches of laboratories since there is a power source small enough to fit the device and able to provide the energy needed for its operation. To realize the micro batteries a team of researchers, based at Harvard University and the University of Illinois at Urbana-Champaign, are able to print with precision the stacks of interleaved comb-shaped electrodes. "Not only do we have demonstrated for the first time that we are able to 3D print a battery, but we have demonstrated unibody damage in a more rigorous way," said Jennifer unibody damage A. Lewis, senior author of the study. unibody damage In recent years, engineers have invented many miniaturized devices, including medical equipment, flying unibody damage insect-like robot and small cameras and microphones that fit on a pair of glasses. But often the battery power as large as or larger than the devices themselves, unibody damage which conflicts with the objective of building micro-devices. unibody damage To overcome this problem, manufacturers have traditionally deposited thin films of solid materials to build the electrodes. However, due to their ultra-thin design, unibody damage these solid-state micro-batteries unibody damage do not provide enough energy to power miniature devices of tomorrow. Scientists have figured out that they could accumulate more energy if they could create stacks of ultra-thin electrodes closely intertwined. For this they turned to 3D printing; these tools by depositing successive layers of material (a special ink) to build a physical object from scratch, a little 'how to stack a deck of cards one at a time. The Lewis Group has significantly expanded the capabilities of 3D printing; have designed a wide range of inks with electrical and chemical characteristics useful for the creation of structures with precise electronic, optical, mechanical. Unlike a traditional printer ink, which comes out as liquid drops that bathe the page, inks developed for 3D printing must meet two challenging requirements: - out of thin nozzles, like toothpaste from a tube; - Harden immediately in their final form. To achieve these objectives, the researchers unibody damage created an ink composed of nanoparticles of lithium oxide (used for the anode), while the cathode unibody damage using nanoparticles of another metal. The printer deposits inks onto the teeth of two combs in gold, creating a stack of closely interlaced anodes and cathodes. To complete the battery electrodes are immersed in an electrolyte solution. The result, the researchers say, it is a battery unibody damage of extremely small size but has the same performance as in the commercial batteries charge levels, life cycle and energy density accumulates. Below you can see a nice movie of the 3D printer in action:
