Nanowired anode

The Amprius cell is a reality, not vapourware

Here's a battery start-up that has real product in the market.

Amprius, yet another start-up from Stanford University isn't actually making batteries but it is producing vital components for them.  Amprius has developed a very special electrode made from silicon nanowires.  Rather than try raising the huge capital needed to build a manufacturing capability, Amprius has partnered with asian based battery producers.

As with many of these next generation technologies, actual information about them is scant.  We do know that the nanowire anode can improve energy density by up to 10 times over the current capability of top of the line lithium ion.  This makes them highly desirable in the electrical vehicle sector.  The maximum recharge cycles could also be greatly higher than current technology with a jump from around 500 cycles to 6,000.  This technology will be based on using carbon nanotubes.  The nanotube structure could allow the device to eventually be printed using a special cellulose paper.  It has the potential to give us 'paper batteries'.

Amprius seems to be doing everything right at the moment, having recently raised $25 million from various sources.
