High-performance miniature power sources could enable new microelectronic systems. Here we report lithium ion microbatteries having power densities up to 7.4 mW cm −2 μm −1, which equals or exceeds ...

The concept of storing charge in three-dimensional (3D) architectures has been pursued for more than a decade 1. Such devices can however only be built by patterning complex interdigitated structures ...

3D printing can be used to manufacture porous electrodes for lithium-ion batteries -- but because of the nature of the manufacturing process, the design of these 3D printed electrodes is limited to ...

Dielectric cure monitors can quantify the capacitance (C) and resistance (R) of a material between two electrodes. These electrodes can be modeled as a resistance in parallel with a capacitance, as ...
