24M Technologies, a US-based battery firm, says it has developed a next-generation electrolyte that could dramatically improve the range and charging speed of electric vehicles (EVs), while performing reliably even in extreme temperatures.
24M Technologies has unveiled “Eternalyte,” an advanced electrolyte it claims delivers a step change in ionic conductivity — the key factor in how quickly a battery charges and discharges.
The company says the breakthrough could power future lithium metal batteries capable of over 1,000 miles of driving range and add 190 miles of charge in under four minutes.
Unlike some cutting-edge battery technologies that require overhauls to charging infrastructure, 24M claims its solution does not rely on high-cost MegaWatt charging stations.
Instead, Eternalyte enables ultra-fast charging using today’s setups.
The electrolyte also promises to solve one of the most persistent EV concerns: performance in extreme cold.
According to test data shared by 24M, the battery tech retains full capacity at 0°C and more than 80% at -40°C, addressing winter-related range drops that plague many current EVs.
Eternalyte is compatible with a range of battery chemistries — including lithium metal, silicon and graphite-based cells — and can be integrated into existing manufacturing processes, reducing adoption costs for producers and automakers.
24M Technologies, which has largely operated under the radar, is now positioning itself at the forefront of next-gen EV development — offering a potential breakthrough without demanding widespread infrastructure changes.
Though the company has not revealed full technical details of Eternalyte, it claims the solution is designed not just for today’s EVs but for the battery demands of the next decade.
