3D Printed Battery

The evolution of smart wearables ranging from healthcare to fashion, has provided customers an immense space to access data easily. In general, conventional Li-ion batteries (LIBs) are generally used to power such devices but they often come in a predefined geometry which limits their easy incorporation. In our lab we have used a highly efficient 3D-printing technology to design and fabricate LIBs especially for smart wearable applications. Our focus lies not only on the electrodes but also on other prime components of a battery like separator membrane, solid-state electrolyte, and packaging material.
