So far, the variety of possible forms is very limited. This is because effective batteries are best produced as a lithium-ion systems, which depend on a liquid electrolyte. Solid techniques that are much more flexible, had been several serious drawbacks – especially the much shorter service life. But in the field, there was considerable progress in recent times.
“There are simply no lithium-ion batteries from solids in the market,” said Corie Cobb by the renowned research laboratory Xerox PARC. Currently leads in this technology but ultimately passed hardly a way. On South Korean research institute in Ulsan is a method now has yet found how to more durable solid-state lithium-ion batteries produce in various forms.
‘) as the electrolyte here is a material is used which is essentially composed of aluminum nanoparticles and lithium. This is in this case treated with a specific polymer that is capable of curing with ultraviolet light. As a result, can be very flexible so that batteries build and paste the desired shape in products.
The material also has the advantage that it has approximately a fluidity of ketchup before curing, explained project manager Sang-Young Lee. Thus it can be placed ideally in the form of a print head. Directly behind the nozzle then provides a UV lamp for curing. This allows, for example batteries in the 3D printing manufacture which can provide data glasses with energy in the form of a spectacle arm. Basically, the imagination knows no limits also for various other applications.>
