Creates dense, ultra-compact batteries from a 3d printer

Battery generated from a 3D printer is 0.1mm but hidden energy equivalent battery on the smartphone.

Recently, researchers from Harvard University and the University of Illinois, said they have found a 'powerful' battery solution with a 3D printer: 'It's just 0.1mm in size, Even smaller than a grain of sand, but with dense power density and the equivalent of today's mobile battery.

The team used a custom 3D printer with 0.03mm wide jets and nanoparticles. The shape of this battery is quite similar to the comb with the last interwoven nodes creating anode and cathode. After the electrode layers are hardened, they are added to the electrolyte.

Scientists say that thanks to its small size, batteries made from 3D printers can be widely used in the robotics industry, medical devices, and electronics. In particular, 3D batteries will open up prospects to increase the battery life for mobile devices such as laptops, tablets and smartphones today.
