Finnish researchers develop more efficient microbatteries
Researchers of Aalto University in Finland have developed manufacturing method for microbatteries with organic electrode materials.
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.
