As people use small electronic devices, even smaller energy storage systems are needed. The key challenge is to make microbatteries able to store large amounts of energy in a small space.

Aalto University researchers have demonstrated the fabrication of electrochemically active organic lithium electrode thin films, which make microbatteries more efficient than before.

Researchers used a combined atomic/molecular layer deposition technique to prepare lithium terephthalate, a recently found anode material for a lithium-ion battery.

The new method is suitable for making battery materials fit for 3D microstructured architectures. Manufacturing the batteries based on three-dimensional microstructured architectures is one way to improve the energy density.
