We recently looked at Infinite Power Solutions’ THINERGY batteries and, no sooner had it gone to “print” when IPS came out with another release that, on the surface, seemed to describe what I had written – if you didn’t pay attention to the details. Fearing that I had talked about stuff that hadn’t been released yet (yes, I glossed over the details), I checked in to figure out what was up.

The deal is that there are two new developments, along with a whitepaper describing the technology and the cost situation. The latter covers the technology from scratch, which is why I came away thinking that either this was old news or I had blown through the gate ahead of time. But the new bits are incremental, to an extent.

First, they increased their capacity density to 1.25 mAh/cm². Second, they implemented double-sided roll-to-roll printing of the cell, effectively doubling that. And, while the whitepaper does indeed reprise the technology, it asserts that, with these developments, they can compete on cost with standard lithium-ion batteries, manufacturing for less than $1 per Wh in volume. Packaged up, they say they can offer the equivalent of 700 Wh/liter, an energy density they claim is 25% above that of standard lithium-ion cells.

And this, of course, without the risk of laptop fireworks (even if that risk has been managed to a low level by lithium-ion cell makers).

You can find more details in their release…
