24M announced the latest addition to its disruptive battery technology portfolio Eternalyte, a transformative new electrolyte developed specifically for lithium-metal batteries. The proprietary, liquid electrolyte formula will enable significant improvements in the cycle life and rate capability of lithium-metal batteries for electric vehicle, energy storage and consumer applications.
This new innovation builds on the recent technology breakthroughs from 24M including 24M ETOP™, its electrode-to-pack battery technology, and 24M Impervio™ its new battery separator. When combined with Eternalyte™ the three new technologies go beyond 24M’s SemiSolid™ and Unit Cell manufacturing platforms and offer a battery technology suite that enables a sustainable energy future.
Until now, solid-state electrolyte technology has been the preferred choice for those trying to commercialize lithium-metal batteries, which have long offered the promise of dramatically higher energy densities. However, safety concerns and short and inconsistent cycle life, caused by lithium or other metal dendrites, continue to limit the commercial viability of lithium-metal cells, including those using SSE-based technologies.

Challenges with SSE’s scalability, cost, fragility, and changes in electrical resistance with cycling are additional issues that need to be solved. 24M’s unique liquid electrolyte, Eternalyte™, combined with Impervio solves these challenges. The combination is a low-cost way to prevent all metal dendrites and achieve excellent cycle life with consistent and low electrical resistance to cathode active materials. Historically, liquid electrolytes used with lithium-metal anodes had poor cycle life, particularly, with rapid charging. Eternalyte™, however, has demonstrated outstanding cycle life even under rapid charging conditions, paving the way for new lithium-metal solutions.
“We are on a mission to deliver transformative battery solutions that overcome critical industry challenges. Eternalyte plays a key role in making that transformation happen by enabling high cycle life lithium-metal batteries,” said Naoki Ota, 24M President and CEO. “While our solutions can be individually integrated into conventional battery products, we believe the most significant benefits are achieved when they are combined. Together, they can deliver a cost-effective and safe 1,000-mile-per-charge battery pack enabling electric vehicles to be fully competitive with combustion engine vehicles.”
