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.
