Scientists Develop Flexible Batteries That Could Make Implants & Wearables Safer

Imprint Energy aims to reshape the battery landscape. Currently available battery technologies limit the pace of improvement in design and functionality of portable electronic devices. Imprint Energy will address these shortcomings with its breakthrough zinc-based rechargeable battery technology, Zinc Poly™.

Zinc Poly™ battery technology removes longstanding limitations on the rechargeability of zinc-based batteries and enables the production of ultrathin, flexible, high energy density rechargeable batteries for significantly lower cost and without the design limitations or safety concerns of other battery technologies.

Using many of the same ingredients found in traditional zinc batteries, our team has developed a chemistry that was initiated by focusing on the electrolyte itself, after which electrodes and current collector layers were optimized to be complementary.


The thinness and flexibility of these batteries make them ideal for implants, the researchers noted, and they could be hugely beneficial to the development of brain-computer interfaces, which are, obviously, implanted into one of the most sensitive organs inside the human body.

Since the electrolyte is the component of zinc batteries that touches everything, stability of the electrolyte affects the performance and longevity. We’ve created a proprietary High Conductivity Polymer Electrolyte (HCPE) that is stable, allows the battery to recharge, can transport ions at a rapid rate, and most importantly, it’s printable to a solid state. No container necessary.
