How to customize batteries according to your requirements? It is very challenging to design a battery to satisfy specific loading. For example, you may need to have a battery that can outup certain current when connected to an electric-driven actuator with a certain resistance. Similarly, for our printable robots, I need to customize the battery since each robot may have a different set of parameters. For the next step for our printable robots project, I will explore the methods to customize printed batteries, which may involve modeling, design, fabrication, and characterizations.
