Abstract
Microbatteries have been gained a lot of importance since the development of micro- and nanotechnologies. Integrating the microbattery system will enable a variety of applications, such as implantable biomedical devices and wireless sensor networks. In this paper, we demonstrated a new method to fabricate three dimensional lithium-ion microbattery using stereolithiography. A UV-curable gel polymer electrolyte resin is first synthesized and characterized. The electrolyte resin is then applied to build into 3D architecture by stereolithography. The gel electrolyte structure is designed into a zigzag shape in order to improve the contact area between electrode and electrolyte. Battery's active material, LiFePO4 (LFP) and Li4Ti5 O12 (LTO), are mixed with the gel electrolyte resin and then flow into the gel electrolyte structure. The result demonstrates a feasibility of lithium-ion microbattery fabricated by stereolithgraphy.
