Japanese Researchers Create Printable Lithium Batteries

A Japanese research group has just begun developing lithium polymer batteries that can be manufactured en masse--with roll-to-roll printing technology. The new lithium battery, designed for use with "a flexible solar battery or display," will be fully printable--and therefore thinner, and subject to cheaper, more efficient production. The research group responsible for the discovery is lead by the Japan-based Advanced Materials Innovation Center (AMIC) of Mie Industry and Enterprise Support Center (MIESC).

According to TechOn,

The sheet-shaped battery is expected to be used with a flexible solar battery or display and to be attached to a curved surface. If the battery is integrated with a solar battery formed on a flexible substrate, it is possible to realize a sheet that can be used both as a power generator and a power storage, AMIC said.
And since it makes use of printing technology, it will be thinner, though larger in area, and will be laminated. The roll-to-roll production will make for cheaper production, though one worries about potential waste generated by such mass printing endeavors.

TechOn continues:

They prototyped two types of batteries. One has an output voltage of about 4V at a room temperature while the other has an output voltage of about 2V. The thickness of the battery is about 500μm [!], but the battery capacity was not disclosed. Its negative and positive electrodes were formed on a flexible substrate by using printing technology.
The researchers say that by 2011, the studies will be complete, and the group will turn to commercial and manufacturing considerations. Indeed--as soon as 2011, we could see lithium batteries rolling out of printing presses.
