A new kind of "smart ink" developed by Harvard scientist Jennifer Lewis, head of the university's Lewis Lab, could enable traditional 3D printers to print tiny battery electrodes the size less than a human hair.
To make the ink, nanoparticles of lithium titanium oxide are added to a vial of deionized water and ethylene glycol. Ceramic balls are used as agitators to break down the particles. The mixture is spun for 24 hours, after which the balls and larger particles are removed using filters and a centrifuge. The resulting ink is placed in a syringe, which is then inserted into a high-pressure dispenser housed in a traditional 3D printer. The custom-made syringe's nozzle tips, as small as one micrometer wide at the opening, allow precise patterning.
The ink is solid under normal conditions, but liquefies under high pressure, so it returns to solid form once it leaves the syringe. The ink is used to print the battery's anode and cathode layer by layer following digital instructions. Finally, a case filled with electrolyte solutions encloses the electrodes to create a working lithium-ion microbatteries.
Using this technology, microbatteries could be in between other components to help reduce the size of the gadgets. The microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that currently only exist in labs because batteries currently available on the market are either not small enough or lack sufficient energy to power them.

一種新的“智能墨水”由哈佛大學的科學家珍妮弗·劉易斯,大學的劉易斯實驗室的負責人發達,可以使傳統的3D打印機打印微型電池電極尺寸比人的頭髮少。
為了使墨中,納米粒子的氧化鋰的鈦加入到去離子水和乙二醇的小瓶。陶瓷球被用作攪拌器來分解的顆粒。將混合物紡絲24小時,球和較大的顆粒在使用的過濾器和離心機之後取出。將所得的油墨被置於注射器中,然後將其插入到容納在一個傳統的三維打印機的高壓分配器。量身定制的注射器的嘴,小到一個微米寬的開口,讓精確的構圖。
油墨是在正常條件下的固體,但在高壓下液化,所以它返回到固體形式一旦離開注射器。使用油墨的通過層以下數字說明打印電池的陽極和陰極層。最後,充滿電解質溶液的情況下封閉電極以創建工作的鋰離子微電池。
採用這種技術,微電池可以是在其他組件之間,以幫助減少小工具的尺寸。該微電池可以從醫學的領域提供電力,以微小的設備的通信,其中包括許多目前僅在實驗室存在,因為目前市場上的電池要么不夠小,或缺乏足夠的能量來為其供電。
