Infinite Power gears up with $13M for thin-film batteries

Infinite Power Solutions, a developer of rechargeable thin-film batteries, has announced that it took $13 million in second-round financing to scale production of its Thinergy line of cells — said to be thinner, more flexible and more energy-efficient than other solid-state batteries on the market.

The Littleton Colo. company says its long-lasting Thinergy technology is best used to store power derived from solar, thermal, magnetic and vibrational sources — making it a potentially key component for some cleantech strategies. To establish itself in this space, Infinite Power will use the new money to build out its sales operations and to support engineers developing new applications for its lithium batteries.

To give you a sense of the size and life-span of these cells, popular uses for Infinite Power’s products include implanted medical devices, radio frequency identification (RFID) tags, biometric sensors, and self-destruct circuits in smart munitions for the military. Their heat resistance in particular makes them ideal for medical and military purposes, the company has said.

There are several other major players innovating in the space as commercialization heats up, including Solicore, Cymbet and Excellatron.

Infinite Power used its last round of investment, which amounted to $35.7 million, to fund construction of its thin-film manufacturing plant in Colorado, the first of its kind. That money came from Core Capital Partners, Applied Ventures, D.E. Shaw & Co., and In-Q-Tel, the venture arm of the Central Intelligence Agency.

The recent round came from Polaris Venture Partners and an unnamed strategic backer, in addition to these existing investors.
