EVE's 4695 Large Cylindrical Battery Fits 37 Models, 280Wh/kg Product Enables 1,000km Range

At the conference, Dr. He Wei, vice president of EVE Energy, delivered a keynote speech titled 'Technological Innovation and Full-Scenario Application Progress of Large Cylindrical Batteries,' introducing the technological breakthroughs and application scenarios of large cylindrical batteries. Large cylindrical batteries feature three key characteristics: standardization, zero expansion, and high strength. In terms of standardization, a single 4695 large cylindrical battery has been adapted for 37 vehicle models, covering everything from A-segment compact cars to full-size SUVs, commercial vehicles, and energy storage sectors. Regarding zero expansion, the circular cross-section of the cylindrical structure offers mechanical advantages that suppress expansion, keeping cell dimensions consistent throughout the entire lifecycle. In terms of high strength, the steel casing is more than six times stronger than aluminum casings, and combined with a gas-electric separation design, it can trigger directional pressure relief within 4 milliseconds, release 50% of heat within 5 seconds, and control the temperature rise of adjacent cells to within 70°C during thermal runaway. In terms of energy density, products at 260Wh/kg and 280Wh/kg have both achieved large-scale vehicle installation, with the 280Wh/kg product enabling a 1,000km range in mass-produced models; the 300Wh/kg product will enter vehicle mass production in 2026; and the 320Wh/kg product is applied in the low-altitude economy sector. For in-situ upgrades, the same cell, with unchanged production lines and structure, can be iterated by switching only the chemical system to produce battery packs of different specifications, such as 80kWh, 98kWh, and 114kWh, allowing automakers to complete performance iterations without altering vehicle structures. EVE Energy adopts a '3+2' chemical system layout, comprising three oxide systems— high-nickel, medium-nickel, and lithium-rich manganese-based, plus two phosphate systems— lithium iron phosphate and lithium manganese iron phosphate. Currently, large cylindrical batteries have been deployed in multiple models, including those for BMW, and large-scale application continues to advance. Beyond passenger vehicles, large cylindrical batteries have expanded into scenarios such as HEV and 12V/48V systems, with the 100C ultra-high-rate technology validated in top global racing events.
