3D Microbattery Architectures with a Discontinuous Element

The microbattery architectures discussed in this section, summarized in Figure 7.17, are composed of at least one electrode phase that is made of discrete elements, usu­ally arranged in an array. Each of the electrode components must be electronically connected using a current collector network. As an electrode arrangement becomes more elaborate, the current collector configuration will need to equally become as intricate. Most of the methods described involve constructing a 3D mold and then filling it with the active components by vapor deposition, electrodeposition, or col­loidal methods. However, alternate fabrication processes, for example direct-write printing, have also been used to construct three-dimensional geometries.
