“This is a very exciting project with ESA under the Building Blocks General Support Technology Program (GSTP), that will enable Xerotech to stay at the forefront of battery pack design,” says Xerotech founder and CEO Barry Flannery, “demonstrating that our proprietary PPR solution exceeds the extremely stringent requirements for space applications will provide tremendous technical validation of a core pillar of Xerotech’s battery safety concept which has already been proven in ground-based applications.’
Xerotech already utilizes its proprietary PPR technology in the Hibernium product line for Off-Highway Vehicles and Non-Road Mobile-Machinery, that was launched in Q4 2020.
The technology, known as passive propagation resistant (PPR) design, is a critical safety requirement of future space missions including manned spaceflight.
Xerotech’s PPR technology is capable of preventing single and multi-cell thermal runaway within a battery pack by utilizing an ultra-lightweight fire-retardant structural foam which is 90% lighter than competing PPR technologies.
The technology can be applied to all current space battery designs and has the potential to enable previously impossible mission profiles and applications.
