Abstract:
Additive manufacturing strategies are gaining more importance in the context
of lithium-ion batteries. The rapid prototyping, reduced waste and complex
3D structures achievable are powerful and attractive tools that are out of the
reach of current fabrication techniques. Additionally, thanks to the potential
that these manufacturing techniques hold for the fabrication of micro-energy
storage devices, they are gaining increasing attention in the literature. Here,
some of the more common additive manufacturing techniques are compared
to standard methodologies by systematically evaluating their electrochemical
performance and correlating it with the physical changes induced by the
printing process. By using LTO/CNT-based inks, it is observed that the inner
arrangement of the conductive additive is significatively altered depending on
the technique used and that this has an impact on the rate performance of
the device. By using a model that links the capacity-rate data to the physical
properties of the batteries, it is possible to find the limiting factor on the
printed electrodes and correlate it with the material arrangement that each
technique produces.
