There may have just been a revolutionary development in electric vehicle batteries.
Eternalyte, an electrolyte developed by 24M Technologies, is expected to completely transform the operation of batteries in electric vehicles. It may be onto something, but it’s big claims.
Instead of using a solid-state electrolyte, this unique sauce (the formula is exclusive) speeds up and increases the rate at which ions travel between the anode and cathode.
The outcome? Using regular charge points, this battery can be charged four times faster than traditional batteries, providing approximately 186 miles of juice in less than four minutes. Yes, ultra-fast charging infrastructure is not required. Granted, according to 24M’s own specification sheet, the battery cell’s gravimetric energy density is 350 Wh/kg, and Merc is developing solid-state batteries with a power density of 450 Wh/kg.
Nevertheless, 24M’s patented liquid electrolyte genuinely has other fascinating qualities. According to the boffins at 24M, Eternalyte helps a battery maintain all of its usability at 0°C and more than 80% capacity if you get down as low as -40°C. At freezing point, cold weather can diminish current battery capacity by roughly 25%. We’ll believe them since we don’t have any polar expeditions scheduled.
Although Eternalyte was created for lithium-ion batteries, lab testing on lithium-metal, silicone-based, and graphite-based batteries has also produced comparable outcomes. Additionally, the battery lifespan has improved.
The CEO of 24M Technologies, Naoki Ota, stated, “Some of the largest problems facing lithium-ion batteries today are resolved by 24M’s Eternalyte electrolyte innovation. Eternalyte offers exceptional performance for applications ranging from EVs to consumer goods thanks to its quick charge, exceptional low-temperature performance, and long cycle life with lithium metal and other high energy density chemistries. It opens the door for next-generation batteries with a 1,600-kilometre driving range and years of dependable performance, such as lithium metal.
It seems like progress to go over 1,000 miles on a single charge, doesn’t it?
