Abstract Scope |
This work will show the development of three-dimensional complex battery electrode structures of high-energy density LiNi1/3Mn1/3Co1/3O2 ceramic material by means of a vat photopolymerization process combined with a precursor approach. This approach involves the solubilization of metal precursor salts into a UV-photopolymerizable resin and the in-situ synthesis of the battery material upon thermal post-processing of the printed item. The particular innovation relies on the introduction of soluble salts into the resin, instead of solid particles, which reduces detrimental light scattering and increased viscosity. Formulation of the composite resin and 3D printing of complex structures, followed by an optimization of the thermal post-processing will be thoroughly described. Moreover, this work will address the need for a compromise between the electrochemical performance and mechanical one in order to obtain fully functional additively manufactured battery electrodes. Finally, it will discuss the gaps that limit the multi-material 3D printing of batteries via the vat photopolymerization process. |
