A battery separator that prevents fires by obstructing dendrite propagation

By Michelle Froese | October 24, 2024

24M Technologies announced the delivery of commercial-sized lithium metal battery cells, integrated with its Impervio separator and Eternalyte electrolyte, to a major automotive original equipment manufacturer (OEM). This milestone marks a significant step toward large-scale production of safer, more reliable, electric vehicle (EV) batteries.

Momentum is building for 24M’s breakthrough Impervio technology, a battery separator that prevents fires by obstructing dendrite propagation. The technology controls the cell at the individual electrode level, preventing dendrites from propagating and enabling early fault detection.

Impervio can prevent a thermal runaway by monitoring the cell’s electrochemistry and enabling a failsafe in the event of a potential short.

The Impervio separator works with all battery formats and easily integrates into existing manufacturing processes. Because of this, OEMs can test and ultimately integrate the technology in their facilities without making significant changes to their current production lines, whether using conventional battery production methods or the 24M SemiSolid process.

With the available 24M prototypes, OEMs can test the innovations for rapid integration and deployment across the automotive industry.

In addition to addressing critical safety challenges, 24M is at the forefront of overcoming other barriers to widespread EV adoption. When combined, 24M innovations like Eternalyte, 24M ETOP, and Liforever, enable a new era of EVs that can achieve up to 1,000 miles of range with batteries that are 100% recyclable.
