Super rechargeable batteries

The good folks at Rolltronics have licensed some oh-so-clever technology from MIT to develop roll printed lithium batteries which will deliver 2x to 4x the power density of today’s lithium versions. The idea is that you produce your batteries using a high speed roll feed like a newspaper, rather than laboriously making individual units.

If this new VoltaFlex technology takes off, it should be really good news for all small device manufacturers, not to mention power hungry consumers. Company presentation here.
