Thin-film lithium secondary batteries that are produced by thin-film deposition technology have special advantages thanks to their unique thin-film shape. They are not only safe to use as a result of their being allsolid-state, but are also thin, lightweight and flexible. They can be employed in small electronic devices and biomedical device ...
Fabrication of the thin-film batteries has been described in earlier publications and on our website , , . The battery is built by a sequence of physical vapor deposition processes. Experimental cells are generally fabricated onto a ceramic alumina substrate. Metal current collectors are deposited by dc magnetron sputtering.
The products produced during this time are sorted according to the severity of the error. In summary, the quality of the production of a lithium-ion battery cell is ensured by monitoring numerous parameters along the process chain.
Production steps in lithium-ion battery cell manufacturing summarizing electrode manufacturing, cell assembly and cell finishing (formation) based on prismatic cell format. Electrode manufacturing starts with the reception of the materials in a dry room (environment with controlled humidity, temperature, and pressure).
Thin-film solid-state rechargeable lithium batteries are ideal micropower sources for many applications requiring high energy and power densities, good capacity retention for thousands of discharge/charge cycles, and an extremely low self-discharge rate.
As the discharge capacity increases, the volume change in the Li anode becomes very large. If the contact area decreases, the utilization of the thin-film battery also decreases. An indium film was introduced as a buffer layer between the Li and Li3 PO 4. However, there was no improvement in the capacity of the thin-film battery.
The morphologies and thicknesses of the thin-film batteries were investigated by field-emission scanning electron microscopy (FE-SEM, SU6600, Hitachi). After the electrochemical tests, the cross sections of the thin-film batteries were observed by FE-SEM. Fig. 1.

Usually, lithium coatings are produced in the form of thin films by roll-to-roll-technologies, which also require the use of lubricants. At Fraunhofer FEP, however, the lithium coatings are produced in a thickness range of 1 – 20 micrometers by thermal vapor deposition in vacuum without any contaminating substances. This allows very pure and ...
